Note: The next 2 LED indications apply to the 20GB drive ONLY Flashing Flashing Flashing When all 3 leds are flashing same as 3 LEDs ON (All LED's can Flash if the drive is powered on and the system to which the drive is connected is powered off or the SCSI cables and terminator are connected to the drive but not to a system.). Flashing * * The tape drive has detected an internal fault that can either indicate an error, as above, or the system is powered off and the tape drive is powered on and connected to the SCSI cable and terminator, same as 3 LEDs ON condition. The LCD will be showing the last 3 errors Where * is On, Off, or Flashing 20GB 8mm tape drive LCD messages: The 16-digit alphanumeric LCD display information: DISPLAY MEANING RESET During the Powerup Sequence the RESET Message comes up first to indicate that the drive is going thru the boot sequence. Then after about 5 seconds, the following messages appear in sequence for 3-4 seconds each. These messages indicate the MODEL: IBM-20GB MODEL SUBMODEL: xxxxxxx SUBMODEL: EEimage in the drive SN: xxxxxxxxxx SN: drive serial number CODE: aaaaaaa CODE: microcode level in the drive LAST CLEAN: xxxhr LAST CLEAN: hours since last cleaning COMPRESSION: ON COMPRESSION: indicates whether data compression mode is ON or OFF SINGLE ENDED SINGLE ENDED or DIFFERENTIAL interface. WIDE WIDE interface only SCSI ID: xx SCSI ID: number 0-15 While the drive is completing the reset the LEDs show that the drive is in the RESET(Power up or Reset) mode. The drive usually completes the reset before all messages complete. LANGUAGE If the eject button is held down during the sequence, English the "Language" prompt appears after the "SCSI ID" Deutsch message, followed by a list of the languages in a slow Espanol scrolling sequence. When the desired language appears Francais on the display, the operator releases the button. The Italiano drive RESETS again, even if it is the same language, Portugues and begins with the new/same language. CLEAN SOON * If the drive cleaning criteria has been reached, the MUST CLEAN CLEAN SOON message displays. with the ICON flashing, CLEANING... during the time that the drive is normally idle, DEPLETED when READY is typically displayed. The Disturbance, AMBER CLEAN LED, is also ON. When the drive has recognized that a clean is in process the word CLEANING... will be displayed during the cleaning process. If the Cleaning Cartridge is at the end of it length, the cartridge is ejected and the DEPLETED message is displayed until a new cleaning cartridge is used or a data tape is installed. When a tape motion command is given, that new message is displayed even though the AMBER CLEAN LED is still on. Then, until the drive is properly cleaned, at each idle opportunity, CLEAN SOON is displayed. Note: MUST CLEAN - The MUST CLEAN message is displayed when the tape is switched from MP to AME and the drive cannot be used to write to the AME tape without first cleaning the tape drive. Any AME TAPE WILL BE EJECTED until the tape drive is cleaned. DISPLAY MEANING READY-NO-TAPE This message appears at the end of the RESET sequence if no tape is loaded. LOADING * This message appears when tape is loading. The ICON will flash during this time. READY-TAPE * This message appears at the end of Loading Tape. ILLEGAL TAPE If a customer inserts an ILLEGAL TAPE, like a cloth cleaning tape, then the tape will be ejected and the ILLEGAL TAPE message will be displayed until a suitable tape is loaded. Note: ILLEGAL TAPE - Only tapes labeled AME(22m or 170m) can be written by this drive. Tapes labeled 15m, 54m, 112m, or 160m are Metal Particle(MP) and cannot be written(e.g. read only). After reading an MP tape, the drive MUST BE CLEANED before being able to write to an AME tape, refer to the MUST CLEAN message. Cleaning tapes supported by the 2.3GB, 5GB and 7GB 8mm tape drive are NOT supported in this drive, if these cleaning cartridges are inserted the "ILLEGAL TAPE" message will be displayed, and the tape ejected. EJECT ** * This message will be displayed, with the ICON flashing whenever the eject button is pressed and the eventual result is to eject the tape. For example, this message will appear even thought the tape drive is continuing to flush the buffer during a READ or a Write, because the eventual result is to rewind and eject the tape. This will give instant acknowledgement to the operator that the button press was received by the drive. The ICON will change to < < (same as Rewind) when the rewind phase is in process. EJECT PREVNT * This message will be displayed if the system has issued a "prevent media removal" command and the drive unload button is pressed. The tape will rewind and unload into the tape cartridge, but the cartridge will not eject from the drive. READ + ** * The + sign appears whenever the drive is in compression mode. The boxes show the amount of tape used as a percent of the total tape length. The empty area is shown as equal sign so that the line is complete. There are up to 6 solid squares to follow the message as shown in the following 5 messages. WRITE + ** * The + sign appears whenever the drive is in PROTECTED compression mode. If a write is attempted on a Write ILLEGAL WRT Protected tape, the PROTECTED message is displayed. The ILLEGAL WRT message is displayed if write is attempted to a for which writing is not supported on this tape drive. This message remains until another tape is inserted that is the correct type or another legal command is issued such as a READ, REWIND, or the eject button is pushed. Note: ILLEGAL WRT - Only tapes labeled AME(22m or 170m) can be written by this drive. Tapes labeled 15m, 54m, 112m, or 160m are Metal Particle(MP) and cannot be written(eg. read only). After reading an MP tape, the drive MUST BE CLEANED before being able to write to an AME tape, refer to the MUST CLEAN message. DISPLAY MEANING SEARCH ** * Used for high speed searching to indicate the position on the cartridge. The display bar will increase or decrease for forward or backward searches. REWIND ** * Self explanatory. Display bar reduces in size as rewind occurs. ERASE ** * Self explanatory. This occurs very quickly for a short erase. WORN TAPE This message is displayed when the tape in the drive is beyond the end of its usefull life(20,000 passes of the tape drive head over any spot on the tape). This counter is an internal counter that is not accessible to the user. This counter was implemented starting in microcode level 40HA. To avoid the possibility of data loss, copy the data you need from this tape to a new tape as soon as possible. LOADING CODE.. If a code load tape is inserted and the tape is CODE LOAD FAIL recognized as such, or a code load is in process via RETRY CODE LOAD the SCSI or Monitor port, then the LOADING CODE.. message is displayed. At the completion of the code load, if there was a failure, CODE LOAD FAIL and RETRY CODE LOAD messages scroll. Otherwise, if the code load was successful, the drive will automatically RESET and come READY again. DIAG-LOAD TAPE If a SCSI Send Diagnostic command is received, or a DIAG-TESTING Diagnostic tape is used, then this series of messages DIAG-PASSED appears. DIAG-LOAD TAPE is used if the command is via DIAG-FAILED SCSI and no tape is present. DIAG-TESTING appears DIAG-WRT xx.x% during this test. DIAG-READ xx.x% If the test passes OK, then the DIAG-PASSED appears DIAG-ECC xx.x% for 15 seconds. If there is a failure, then DIAG-FAILED appears and the 3 statistics messages appear for 2 seconds each in a rotating loop. Pressing the Eject button to remove the tape will clear this display. Otherwise this message will continue to display DIAG-FAIL(plus the 3 statistics messages) until the drive is RESET. ERR 1: xx yy zz Failing error codes displayed when the drive is first ERR 2: xx yy zz powered on or during tape drive operation. ERR 3: xx yy zz Where xx is the fault symptom code. Where yy is the primary error code. Where zz is the secondary error code.

Tape Drive Performance/Reliability Checklist The Tape Drive Performance/Reliability Checklist is an overview of how to evaluate and prevent tape drive problems. Media Selection Use only the tape cartridges supported by your tape drive. These must be high quality data grade media, such as the IBM data grade cartridge originally supplied with your drive. Don't attempt to write on previously written software distribution tapes. Often these tapes will not support being rewritten without modifications to the cartridge. If the cartridges are modified it is possible to cause tape jams or misalignment. The following is specifically addressing 8mm media: - 8mm media of 15m, 54m, 112m, or 160m length is Metal Particle(MP) media. - 8mm media of 22m, 125m, or 170m length is Advanced Metal Evaporated(AME) media. - 8mm AME 125m media is not supported in the IBM 20GB 8mm tape drive. This media will be ejected if inserted. - 8mm drives with 2.3GB or 5.0GB capacity Read/Write 15m, 54m, or 112m length "MP" media only. - 8mm drives with 7.0GB capacity Read/Write 15m, 54m, 112m, or 160m length "MP" media only. - 8mm drives with 20.0GB capacity are Read-ONLY on 15m, 54m, 112m, or 160m length "MP" media. - 8mm drives with 20.0GB capacity can Read/Write ONLY on 22m, or 170m length "AME" media. - 8mm media of 22m, 160m, and 170m should bear the Recognition System Logo. The following chart shows the various 8mm tape drives and their supported media with cleaning cartridge, recommended minimum cleaning frequency, and corresponding IBM Media part numbers(P/N): Drive Type 15m MP 22m AME 54m MP 112m MP 160m MP 170m AME Cleaning ----------------------------------------------------------------------------------- | 2.3GB | R/W | N/S | R/W | R/W | N/S | N/S | 30hr/Monthly| | | N/A | | N/A | 21F8575 | | | 16G8467 | |---------+---------+---------+---------+---------+---------+---------+-------------| | 5GB | R/W | N/S | R/W | R/W | N/S | N/S | Amber LED | | | N/A | | N/A | 21F8575 | | | 16G8467 | |---------+---------+---------+---------+---------+---------+---------+-------------| | 7GB | R/W | N/S | R/W | R/W | R/W | N/S | Amber LED | | | N/A | | N/A | 21F8575 | 87G1603 | | 16G8467 | |---------+---------+---------+---------+---------+---------+---------+-------------| | 20GB | Read* | R/W | Read* | Read* | Read* | R/W |LCD/Amber LED| | | N/A | 59H2671 | N/A | 21F8575 | 87G1603 | 59H2678 | 59H2898 | ----------------------------------------------------------------------------------- * This media is Metal Particle(MP) the 20GB drive MUST BE CLEANED after reading this media prior using Advanced Metal Evaporated(AME) media. R/W - This drive can both Read and Write this media. Read - This drive can ONLY Read from this media. The drive cannot write on this media. N/A - IBM does not have a P/N for this media. N/S - The tape drive does Not Support Reading or Writing on this media. Media Replacement Cartridges which are used regularly (e.g. daily/weekly backup tapes) should be discarded after about a hundred uses. Cartridges which are in use when media-related errors are reported by your backup application, or are physically dropped, or are exposed to extremely harsh envi- ronments should be discarded. Media Storage Protect your cartridges from particulate contam- ination when they're not in use. Put each car- tridge in its protective case or place the cartridge in a dust-tight container designed for tape cartridge storage. Keep your cartridges in an area where the temperature and humidity are comfortable for you and are relatively constant. Orient cartridges in storage so that their cases are on an edge (vs flat). If cartridges are moved between areas whose temperature or humidity differ greatly, let the cartridge adapt for several hours prior to use. Cleaning Cartridge Selection/Usage Use only the cleaning cartridges supported by your tape drive. These must be high quality car- tridges, such as the IBM cleaning cartridge ori- ginally supplied with your drive. Refer to the "Media Selection" for proper cleaning cartridge part numbers and their minimum recommended usage. Cleaning Cartridges used in the 2.3GB, 5.0GB, and 7.0GB drives are different from those used in the 20.0GB drives. Clean your drive once a month or whenever the AMBER LED is turned on solid(not applicable to the2.3GB drives). Clean your drive after any media related error is encountered. Often software distribution tapes are MP media. The 20GB drive MUST BE CLEANED after using MP media (15m, 54m, 112m, or 160m length media) before any subsequent write operation will be allowed. Clean your 2.3GB drive after every 30 hours of reading and writing activity. Observe the remaining cleaning material through the cartridge's window and discard the cartridge when fully used. Environment Locate your tape drive at table top level or higher and away from sources of particulate contamination such as outside doorways, high foot traffic areas, printers, and copiers. Maintain comfortable tem- perature and humidity (ideally 30-40% Relative Humidity) when the tape drive is in use. Note that this may require a timing adjustment of nighttime setbacks. Minimize the amount of time cartridges spend in the drive when not in actual use. Troubleshooting If a backup failure occurs, try cleaning the drive and retrying the operation with a new cartridge. Verify that this checklist's recommendations are being followed by the system's operators. Look for trends, process changes, and/or environmental changes. Avoid mechanical loading problems by placing labels only in the designated cartridge spine and top locations and assuring that they are not peeling off or more than two layers thick. Contact your IBM CE if problems persist.

Note: 8mm 2.3GB, 5GB, 7GB, & 20GB tape drives will log a TAPE_ERR3 when: Rewrite % is equal to or greater than 2% with at least 100mb of data written, or Reread % is equal to or greater than 1% with at least 20mb of data read. Note: The 20GB drive MUST BE CLEANED after using 15m, 54m, 112m, or 160m length media before any subsequent write operation will be allowed. Note: TAPE_ERR3 and TAPE_ERR6 are "soft errors" that are posted to the AIX error log. In other words, neither error terminated the tape operation. They are informational errors that may cause AIX to send an informational message to the user. Note: TAPE_ERR4 errors are often found to be caused by noise on the SCSI bus. Noise on the SCSI bus can be caused by one or more of the following: - Loose SCSI Cables (reseat and tighten all SCSI connections). - Bent pins in the SCSI connection (check all SCSI connections for bent pins). - Device is not supported on the SCSI adapter/system(insure device is supported by the SCSI adapter/system). - Improper, missing or multiple SCSI bus termination(check SCSI bus termination). - SCSI cables(insure the proper IBM SCSI cables are used). - SCSI cables exceed the supported length for the bus(check the IBM information on SCSI bus length). - Other SCSI devices on the bus(it may be necessary to remove the other SCSI devices one at a time to determine device causing the problem). Tape Drive Problem Determination Details the steps that should be taken to resolve user reported problems. Tape drives are very expensive and often are not the reason a customer cannot read or write a tape. Often the problem is caused by one or more of the following: - Bad blocksize, the customer attempts to read at one blocksize and the tape is written at another. Or the blocksize the customer is attempting to write at is preceded by a 0 (ZERO), 0512 is not the same as 512. The zero is recognized by the system as Octal and some applications do not support Octal values. - Device buffering turned off causing the drive to write every block of data as it is received. Normal operation is to buffer the data allowing the drive to stream the data to the tape as a continuous operation. - Writing a tape with one command then attempting to read the tape with a non compatible command, such as: writing the tape with a "tar" command and attempting to read the tape with a "restore" command. - Poor Quality media, or worn out media being used. Clean the drive and retest the customer operation with a new IBM data cartridge recommended for the drive. - Misunderstanding of the meaning of the LED's on the tape drive. - Customers not cleaning the tape drive, using cleaning cartridges that are used up, or not following the recommended cleaning frequency or cleaning instructions. - Not cleaning the tape drive after an I/O error prior to retrying the failing operation. - Improper SCSI bus termination. - Conflict of tape drives SCSI address with another device on the bus. - Other device causing "noise" on the bus. - Environment not suitable for tape drive operation. - PTF's level of the system does not support the tape drive. If a customer is experiencing problems with IBM tape drives, 1/4", 4mm, 8mm, or DLT tape drives you should do the following before replacing any parts: Note: There may be times when you want to reset a tape drive to clear an error condition(including stuck tape) without powering off the tape drive. It is possible on most IBM 1/4", 4mm, 8mm, and DLT tape drives to reset the tape drive by pressing and holding the eject button depressed for 15-30 seconds(drive power must be ON). Another way to reset the tape drive is to sign on the system with root authorizaion and issue the AIX command: diag -c -d 1) Clean the tape drive using the IBM Cleaning Cartridge: 1/4" Tape Drives Cleaning Cartridge P/N 16G8572(Not for 7207-122/315) 50 Cleanings 1/4" 7207-122/315 Tape Drive Cleaning Cartridge P/N 59H4366* (Only for 7207-122/315) 50 Cleanings *Replaced P/N 46G2674 4mm Tape Drives Cleaning Cartridge P/N 21F8763* 50 Cleanings *Replaced P/N 59H3090 8mm 2.3GB, 5GB, and 7GB Tape Drives Cleaning Cartridge P/N 16G8467 (Do not use this cleaning cartridge on the 20GB 8mm Drive) 12 Cleanings on 2.3GB Drive 22 Cleanings on 5GB & 7GB Drive (On the 5GB 8mm tape drive Microcode 6S0 or higher is required, the 2.3GB and 7GB 8mm drives support this cleaning cartridge with no microcode dependency.) 20GB Tape Drives Cleaning Cartridge P/N 59H2898 (Only use this cleaning cartridge on the 20GB 8mm Drive) 18+ Cleanings (18+ because drive varies cleaning tape used based on cleaning from MP tape or AME tape, etc.) DLT Cleaning Cartridge P/N 59H3092 20 Cleanings 2) Determine that there is no conflict of SCSI addresses between the tape drive and any other SCSI device. lsdev -Cs scsi 3) Check all SCSI connections. Insure all connections are secure, screws or clips are tightly attached. 4) Insure the proper terminator is in use. Check the P/N. Insure the terminators are securely attached. 5) Run the tape drive diagnostics using the IBM test tape or diagnostic tape: 1/4" Tape Drives Test Tape P/N (Diagnostics will fail if the wrong tape is used in the 1/4" drive) 150mb drive, 7207-001, QIC-150 92X7510 520mb drive, 7207-011, QIC-525 21F8586 1.2GB drive, 7207-012, QIC-1000 21F8734 4GB drive, 7207-122, SLR5-4GBSL 59H3661 13GB drive, 7207-315, QIC-5010-DC 87G1626 4mm Tape Drives Diagnostic Tape P/N 4mm 2GB drive, 7206-001, DDS|||| 21F8762 (Usage is counted and there is a maximum of 50 uses) 4mm 4GB drive, 7206-005, 7332-005 DDS2 8191146 (Usage is counted and there is a maximum of 50 uses) (Bug in diagnostics can produce false 915-200 error, refer to RETAIN tip H126264) Test Tape P/N 4mm 12GB drive, 7206-110,7332-110 DDS3 59H3466 4mm Internal Autoloader ONLY(DDS||||) 73H3467 8mm Tape Drives Test Tape P/N 2.3GB drive, 7208-001 21F8577 5GB drive, 7208-011 21F8577 7GB 7331-205 21F8577 20GB drive, 7208-341, 7331-305 59H2677 DLT Tape Drives Test Tape P/N 35GB 7205-311 59H3039 6) Review the AIX Error Log for all errors around the time the customer is unable to process the tape. The AIX command to review the log is: errpt -a | pg 7) Do a dd of the tape to determine if there is data on the tape and also determine the blocksize the tape was written at. - Determine the blocksize currently set for the tape drive on the system. Remember this blocksize: lsattr -El rmt0 - Set the tape drives blocksize to 0 (if not already at 0): chdev -a block_size=0 -l rmt0 - Determine the blocksize the tape was written at: dd if=/dev/rmt0 bs=128k count=1 | wc -c - Use the chdev command to set the blocksize for the tape. - Process the tape. - Set the tape drives blocksize to the previous setting(you remembered 8) If another system is available attempt to read the customers tape on the other system. If it can read the tape then check the blocksize set in the "good" system to insure it matches the system where the tape could not be read. 9) Often customer media problems cause drive replacements. Media problems can be identified by having the customer clean the tape drive several times and write and read from new IBM media. This will often result in a customer replacing a single tape that solves the customer problem. Check what brand of media the customer is using and insure it is supported on the device.

These systems require internal tape drives to have isolators on the sides of the tape drives. When replacing a tape drive it is important to insure the 7013 systems that require tape drive isolation have the isolator installed on the tape drive. Insure the isolators are installed on the customers 7013 if required. Isolators are shipped with the FRU. The following are the isolators required: Isolator P/N's 4mm Tape Drives Right P/N Left P/N Rear P/N 4mm 4GB drive 43G0803 43G0804 None Required 8mm Tape Drives 2.3GB drive 00G3294 00G3295 None Required 5GB drive 43G0803 43G0804 51G9698 20GB drive* 43G0803 43G0804 51G9698 * 7013-595 and higher Only 12)Only after all this is done should the tape drive be exchanged. 1/4" Tape Drives FRU P/N 150mb drive, 7207-001, QIC-150 16G8423 520mb drive, 7207-011, QIC-525 46G2700 1.2GB drive, 7207-012, QIC-1000 21H5155 4GB drive, 7207-122, SRL5-4GB 59H4434* 13GB drive, 7207-315, QIC-5010 87G4858 * FRU for 7207-122 is whole enclosure including drive and P/S. 7013-Jx0 4mm Tape Drives FRU P/N CRU P/N 2GB drive, 7206-001, DDS|||| 8191193 4GB drive, 7206-005, DDS2 59H3481 19H0213 4GB 7248-43P drive DDS2 59H3480 12GB drive, 7206-110, DDS3 59H3879 Black/White Bezel 4GB Internal autoloader Horizontal 76H0474 DDS2 4GB Internal autoloader Vertical 76H0473 DDS2 7332-005, DDS2 59H3553 7332-110, DDS3 59H4168 7336-205, DDS2 59H2823 7013-Jx0 8mm Tape Drives FRU P/N CRU P/N 2.3GB drive, 7208-001 16G8421 5GB(SE) drive, 7208-011 59H3159 19H0204 5GB(DE) drive 59H3160 7GB(DE) 7331-205 59H3161 20GB(SE) White Bezel 59H2839 20GB(SE) Black Bezel 59H4120 20GB(DE) 7208-341 59H2835 20GB(DE) 7331-305 59H2842 DLT Tape Drives FRU P/N 35GB 7205-311 59H3121 Note: Retest the failing process. If the customer process still fails put back in the customers system the original tape drive and continue problem determination. If the failing process passes with the new tape drive return the failed tape drive. ==================================================================== Note to CE: You are the person on site at the customer and know what is happening at the customer. The support areas need some specific information to help you diagnose the problem. Please have the resulting information from items: 1, 2, 4, 5, 6, 7, 8, 10, and 11 available to discuss with support when you contact them. The following is normally what will be requested by support: Problem number, branch office, customer name, system type and model, and tape drive type and model. For items: 1) What cleaning cartridge is the customer using, name and description. 2) The results of the lsdev -Cs scsi command 4) What are the terminator P/Ns 5) Diagnostic results 6) Contents of Error Log, for example Tape_Err1 etc. 7) What blocksize is the customer using 8) Results, worked or did not work. 9) What media is the customer using, specifically what media did the tape drive fail to properly handle. 10) The Z1 field information. 11) Were the isolators installed if the system is a 7013-560 thru 7013-59x ? ==================================================================== Help Desk Guidelines The following is an outline of how a customer help desk should operate with regard to tape drive operations: The key to resolving the problems is to determine what is different between success and failure at one site or between sites. To do this the following will help: - Establish and publish backup practices. This helps all understand the importance of the data being backed up, what is expected to be done, and who is responsible for doing each item. - Establish and publish help desk procedures. This is helpful to both the help desk and the customer sites. This helps both understand what is expected of each other plus identify what is to be done by each. - Media must be standardized, sites should get media, both data cartridges and cleaning cartridges from the same source. Provide the sites a simple way to get the data cartridges and cleaning cartridges they need. This reduces the risk of unsupported media from being used. - Label each data cartridge with the day of the week(on the data cartridge). Each site should always have a new sealed spare data cartridge. - Label each data cartridge and cleaning cartridge with the date the customer first put it in service. - Manuals shipped from IBM with the system or tape drive need to be kept with the system for Customer and CE use. - Each tape drive is shipped from IBM with a Diagnostic/Test cartridge. This cartridge needs to be kept with the drive for Customer and CE use. - Monitor cleaning to insure the tape drives are cleaned on a regular basis. Tpusage - can be used for the 4GB 4mm tape drive. Cleanchk - can be used for the 5GB and 7GB 8mm tape drive. Utape - can be used for the 13GB 1/4", 12GB 4mm, 20GB 8mm, and 35GB DLT tape drives. Utape is part of the AIX diagnostic package. Tpusage and Cleanchk are available from your IBM CE or IBM marketing as "use as is programs". - Determine cleaning cartridge status and discard used up cartridges. Each site should always have a new sealed spare cleaning cartridge. - Monitor backups to determine the following: - Insure backup completed successfully - Determine the type of backup failure and track the following for that site: - Was the backup attempted? - Did the backup put an error in the AIX error log. - TAPE_ERR1 is likely a media failure. Did terminate the backup. - TAPE_ERR2 is normally a drive failure, but can be caused by a media failure. Did terminate the backup. - TAPE_ERR3 is likely media starting to fail. Did NOT terminate the backup. - TAPE_ERR4 Unknown cause requires further analysis. Did terminate the backup. - TAPE_ERR5 Unknown cause requires further analysis. Did terminate the backup. - TAPE_ERR6 5/7GB, and 20GB 8mm tape drives log this error when the drive exceeds the preset limit of tape motion hours since the drive was last cleaned. Did NOT terminate the backup. Note: The 20GB 8mm will also set the cleaning indicator and log the TAPE_ERR6 on most media errors. - Log the day of the week, and track this to determine if one tape is failing or are all failing. This will identify media or drive problems. - Over cleaning a tape drive will not normally damage most tape drives when the approved cleaning cartridge is used. On every backup failure where backup was attempted and failed, the tape drive should be cleaned with the approved cleaning cartridge. Note: On some drives over cleaning may damage the drive, review the drive information on cleaning, on those drives follow the drive recommendation. - Prior to placing a service call attempt a simple backup to another tape cartridge to help determine the cause of the failure. Often replacing a single data cartridge will resolve the problem. - When a service call is required, allow time and access for the CE to do problem determination and problem correction. This includes allowing the CE time and access to run diagnostics prior to and after parts replacement. It is desirable to allow the CE authorization to run concurrent diagnostics, a special id may be required for this as it requires root authorization. This will allow the CE to do problem determination without having to take the system down for dedicated CE diagnostics. - Sites that are dusty should keep the system at least 24" off the floor to reduce the exposure to dirt and contamination. - Sites that show persistent media and drive failures that are following established cleaning and media procedures should be considered for filter enclosures.

Some applications take the blocksize and block the data block into larger blocks for transfer to the tape drive. Some applications call this the blocksize, or the buffer size or blocking factor. Whatever it is called you need to understand that this tape drives performance(data rate)is greatly effected when the system sends small blocks of data. Try setting the tape drive block size to a large block size and large blocking factor. You should test your application to see at what blocksize and need to test your application to see at what blocking you get the best performance for your tape drive. The minimum recommended blocking for this drive is 32k. Some AIX commands already use 32k or larger blocks when writing, some do not. The following are a few of the AIX commands and blocking information: backup <- will either use 32k or 51.2k as default depending if backup by name or not. No customer change required. tar <- default is 10k (error in tar manual stating 512kb) tar needs the customer to use at minimum -N64 mksysb <- uses backup on AIX 4.1 No customer change required. dd needs the customer to use at minimum bs=32k cpio needs the customer to use at minimum -C64 Users should insure the blocksize they select is supported by the users application. 4mm Tape Interchange Information The following is a chart that shows the interchange using the IBM 4mm data grade tape among the IBM 2GB 4mm drive, the IBM 4GB 4mm and the 12GB 4mm tape drive.

Some applications take the blocksize and block the data block into larger blocks for transfer to the tape drive. Some applications call this the blocksize, or the buffer size or blocking factor. Whatever it is called you need to understand that this tape drives performance(data rate)is greatly effected when the system sends small blocks of data. Try setting the tape drive block size to a large block size and large blocking factor. You will need to test your application to see at what blocking you get the best performance for your tape drive. The minimum recommended blocking for this drive is 32k. Some AIX commands already use 32k or larger blocks when writing, some do not. The following are a few of the AIX commands and blocking information: backup <- will either use 32k or 51.2k as default depending if backup by name or not. No customer change required. tar <- default is 10k (error in tar manual stating 512kb) tar needs the customer to use at minimum -N64 mksysb <- uses backup on AIX 4.1 No customer change required. dd needs the customer to use at minimum bs=32k cpio needs the customer to use at minimum -C64 Users should insure the blocksize they select is supported by the users application. As an example: Using a blocksize of 1024 and backing up 32GB of data will take approximately 22 hours. Same 32GB of data backed up at a block size of 32k will take approximately 2 hours. Small blocksizes have a significant impact on performance but only a minimal impact on capacity. However 2.6 format(density) and 6 format(density) are significantly impacted in capacity by using small blocksizes, they don't pack the data in the drives internal 8k block. rmt retension/rewind settings ----------------------- RMT D1/D2 | Retension*| rewind** | D1 = density 1 used -----------------+-----------+-----------| D2 = density 2 used | rmt0.0/4 | no | yes | * 4mm & 8mm ignore this. |-----------------+-----------+-----------| ** Rewind on open, does not | rmt0.1/5 | no | no | control on insertion. |-----------------+-----------+-----------| | rmt0.2/6 | yes | yes | |-----------------+-----------+-----------| | rmt0.3/7 | yes | no | ----------------------------------------- Tape Drive Cleaning Frequency Details the recommended tape cleaning frequencies* and proper cleaning cartridge to use for the 1/4", 4mm, 8mm, and DLT tape drives. Other information you should be aware of: It may be necessary to clean more often then the recommended schedule when using new tapes as new tapes often have generate more debris than tapes that have been used a few times. Whenever a tape drive reports an I/O error the drive should be cleaned prior to retrying the tape operation. The 4mm and 8mm cleaning cartridges move the cleaning media from the supply spool to the take up spool in the cartridge during the cleaning operation. When cleaning is complete the area of the cleaning media used in cleaning is wound onto the take up spool, unlike data cartridges that rewind all the media back onto the supply spool. To determine if a 4mm or 8mm cleaning cartridges is used up users should not only check the number of remaining cleanings as marked on the cartridge but also observe the remaining media on the supply spool. To do this: The user should hold the cleaning cartridge as if they were going to insert the cleaning cartridge into the drive. If all, or most, of the media is on the right hand, take up spool, and very little media is still on the supply spool, the cleaning cartridge is used up and will not clean the tape drive. There are times when it will be necessary to use the recommended cleaning process several times in a row to clean the drive: Tape drives that have not been cleaned according to the recommended schedule. Tape drives where unsupported media or cleaning cartridges were used. Tape drives reporting repeated I/O errors. Tape drives operating in dirty/dust environments. If repeated cleanings and new media do not eliminate the I/O errors it may be necessary to replace the tape drive. 1/4" Cleaning Frequency Type Machine Cartridge #Uses Frequency For Cleaning* 1/4" 150mb 7207-001 16G8572** 50 After 2 hours of tape movement on a new tape or every 20 hours of tape movement on a used tape. 1/4" 525mb 7207-011 16G8572** 50 After 2 hours of tape movement on a new tape or every 8 hours of tape movement on a used tape. 1/4" 1.2GB 7207-012 16G8572** 50 After 2 hours of tape movement on a new tape or every 8 hours of tape movement on a used tape when used in QIC-1000 mode, or every 12 hours of tape movement on a used tape when used in QIC-120/150/525 mode. 1/4" 4GB 7207-122 59H4366*** 50 Every 8 hours of tape movement. 1/4" 13GB 7207-315 59H4366*** 50 Every 50 hours of tape movement or when Amber LED(Disturbance LED) indicates either: - 50 hours of tape motion - Hard Read or Write Error * If tape errors or tape job failures occur the drive may have to be cleaned more frequently. ** Replaced 21F8570, was Isopropyl Alcohol *** Replaced 46G2674 late 1998 4mm Cleaning Frequency Type Machine Cartridge #Uses Frequency For Cleaning* 4mm 2GB 7206-001 21F8763** 50 Every 30 hours of tape movement or 4mm 4GB 7206-005 " once a month, or when Amber LED 4mm 12GB 7206-110 " (Disturbance light) indicates 4mm Internal Autoloader " recording quality problems. 4mm Autoload 7332-005 " 4mm Autoload 7332-110 " 4mm Library 7336-205 " * If tape errors or tape job failures occur the drive may have to be cleaned more frequently. ** Change from 59H3090(20 Cleanings) in early 1999 Note: Starting with microcode level 5AL0 the 4GB 4mm drives will not only put ON the cleaning LED based on soft errors but will also put the cleaning LED ON after 30 tape motion hours without the drive being cleaned. 8mm Cleaning Frequency Type Machine Cartridge #Uses Frequency For Cleaning* 8mm 2.3GB 7208-001 16G8467** 12 Every 30 hours of tape movement or once a month, approximately 30GB of data transfer. 8mm 5GB 7208-011 16G8467** 22 Every 30 hours of tape movement or once a month, or when Amber LED (Disturbance LED) indicates 30 hours of tape movement. 8mm 7GB 7331-205 16G8467*** 22 Every 30 hours of tape movement or once a month, or when Amber LED (Disturbance LED) indicates 30 hours of tape movement. 8mm 20GB 59H2898**** 18+ Every 72 hours of tape movement when using AME media(10 hours with MP media) or once a month, or when Amber LED (Disturbance LED) indicates 72 or 10 hours of tape movement or when the Amber LED indicates recording quality problems or when the LCD says "MUST CLEAN" or when the LCD says "CLEAN SOON'. * If tape errors or tape job failures occur the drive may have to be cleaned more frequently. ** Replaced 21F8593 *** DO NOT USE on the 20GB 8mm drives. **** ONLY USE on the 20GB 8mm drives.

Care must be taken not to set two devices to the same SCSI address as this will cause errors that are often not easy to detect. Sets the priority of the device on the bus. Tape drives are normally slow devices compared to harddisks and the tape drives should be set to a high priority to insure the tape drive gets access to the bus in a timely manner. The SCSI bus priority on a RS/6000: Highest 7 6 5 4 3 2 1 0 15 14 13 12 11 10 9 8 Lowest Most SCSI devices will need to be powered OFF then ON again for the device to recognize the new address if the device address was changed with the device powered ON. In general the SCSI adapter will be set at SCSI address of 7, but this is not always the case, so it is best to determine the SCSI address of the SCSI adapter. To determine the SCSI adapters in the system do the following AIX command: lsdev -C | grep scsi The output will be: scsi0 Available 00-04 SCSI I/O Controller To be sure of the SCSI adapter address do the following AIX command for the adapter you are going to attach to: lsattr -El scsi0 | grep id The output will be: id 7 Adapter card SCSI ID Note: High Availability(HA) systems often use 5 and 6 as the SCSI adapter address. Some systems restrict the SCSI address, refer to your system manuals to determine any system restrictions. To be sure of the addresses of other devices are already using on the SCSI bus do the AIX command: lsdev -Cs scsi Valid SCSI addresses for Narrow devices(8 bit) are 0 thru 7, with 7 usually reserved for the SCSI adapter. Valid SCSI addresses for Wide devices(16 bit) are 0 thru 15 with 7 usually reserved for the SCSI adapter. When a Wide device is attached to a narrow bus the available addresses are the same as if the device was a narrow device. Note: On systems that use the Common Hardware Reference Platform(CHRP), the SCSI address 15 may be used for CHRP address. The backplanes use this address on CHRP boxes to ID backplane FRU locations codes in CHRP Error logs. The ID 15 is hard wired into the I-35 backplane. Any devices tagged with a SCSI address of 15 and attached to the SCSI interface used by the backplanes are going to have a conflict of address, so if in doubt don't use the SCSI address of 15. Some systems use more than 1 CHRP and use more than 1 SCSI address on the same SCSI adapter.. Currently the F50, H50, S70, and SP2 equivalents use CHRP. The lsdev -Cs scsi command will show the following(adapter ID will vary): ses0 10-68-00-15,0 SCSI-Enclosure Services Device There may be multiple SCSI adapters in the system an each may have a SCSI-Enclosure Services Device at address 15. Tape Drive Performance The following information applies to most AIX tools(tar, cpio, backup, restore, dd, etc..) used to write or read data from tape, backup and restore are used as generic names only. Customers backing up the same size data or restoring data can find that the amount of time it takes to backup/restore data may vary from backup to backup or restore to restore. Most tape drives work best when the tape drive can keep the tape moving at a constant speed(streaming). The more the tape drive is able to keep the tape streaming the shorter the backup/restore time will be. The ability of the tape drive to keep the tape streaming is effected by many factors. These factors include: Tape drive rated performance. System performance, fast vs slower system. . System activity can often effect the time it takes to do a backup/restore. Backup/restore are best done during periods of low system activity to reduce the impact on other system operations and on the backup/restore operation. Make sure the backup is not done with other system activity that could effect the ability of the system to deliver the data to the tape drive. Such as other devices on the SCSI bus with high activity, or other system activity. SCSI bus Activity on either the SCSI bus with the disks or the SCSI bus with the tape drives. High activity on either SCSI bus may effect the ability of the system to keep the tape drive streaming. Some tape drives, when used on an AIX system, may provide the best performance when written to in the fixed block mode. If your application writes tapes in variable blocked mode, you may find that by changing your application to write in fixed block mode your backup or restore may take less time. It is recommended that if you are currently using variable blocked mode you try changing your backup to a fixed block mode and compare the backup and restore time to the time it took in variable mode. AIX commands used. Depending on the AIX command used system backup/restore time may vary. Some tape drives are sensitive to the delivery of data to the tape drive. Some applications take the blocksize and block the data block into larger blocks for transfer to the tape drive. Some applications call this the blocksize, or the buffer size or blocking factor. Whatever it is called you need to understand that some tape drives performance(data rate)is greatly effected when the system sends small blocks of data. Try setting the tape drive block size to a large block size and large blocking factor. You should test your application to see at what blocksize and blocking factor you get the best performance for the tape drive you are using. Options chosen on the AIX commands. Some AIX commands have options that can improve performance. Refer to the command reference for the commands you are using for the a description of the options. Buffer size(the size of the data transfer AIX uses to communicate with the tape drive). Often increasing the buffer size will reduce the amount of system overhead required to transfer data to or from the tape drive. Reducing system overhead often results in better performance and faster backup/restore times. Refer to the command reference for the commands you are using to increase the buffer size. Tape drive compression setting On or Off. Not only does the option have to be set but if compression is selected the tape drive and media must both support compression at the recording density specified. The ability of the data to be compressed. Some data, such as text data, is often highly compressible, graphic or binary data is often not very compressible. Data that is more compressible will normally take less time to backup/restore because of the use of specialized compression chips in some tape drives. AIX command compression option. Compressing data before sending the data to the tape drive may increase elapsed time depending on the type of data and system activity. Data compression done by the drive will often result in faster backup/restore, but due to other considerations such as network backup, etc., it may be faster to compress the data prior to sending the data to the tape drive. Clean the tape drive with the approved cleaning method. If the tape head is not clean the drive may have to rewrite/reread the data. To reduce the need to rewrite/reread data the tape drive should be cleaned as recommended in the user manuals. The physical condition of the tape can have a impact on the time it takes to do a backup or restore. If a tape is not in the best condition the tape drive may have to rewrite/reread data in order to do the backup/restore. This will this will increase the time it takes to do the backup/restore. Block size, can effect the time for backup/restore. Using large blocksizes may improve performance. Using small block sizes can increase system overhead but before changing to a large blocksize it is necessary to be sure the user application supports the larger blocksize chosen. Very long restore times due to blocksize. If a backup is done with a fixed block length then the restore should be done with the same fixed block length. If a backup is done with a fixed block length and the restore is done with variable block length, the restore may work successfully but it may take many more hours to restore than it took to back up the data. The reason for this is that when AIX reads fixed block length data in variable block mode, a check condition is issued by the tape drive on every read. AIX must interpret every check condition and determine the proper action to take. This often will put the tape drive into a mode of reading that will require the tape drive to stop tape motion, rewind the tape some distance, then start reading again. This will reduce the life expectancy of the tape and increase the time it takes to backup data. Eliminate as many rewinds as you can. Do not write one file then rewind only to then space out to the end of the last file written to write a new file. Use the .1 parameter on the rmt to reduce tape repositioning. Do not use this option with the AIX mksysb command as mksysb handles tape positioning and rewind itself. Device Driver/Robotics Driver Atape is the device and robotics driver for the 7332-005 and 7332-110. Atape is the robotics driver for the 7331-205, 7331-305, and 7336-205. Note: A minimum Atape level required for microcode download on the 7332-005 or 7332-110 is Atape 2.5.2.10. To check the level of the Atape driver on a system do the following AIX command: lslpp -l Atape.driver The current level of the Atape driver can be obtained(downloaded) via anonymous ftp service. Access the ftp server as you would an anonymous service. The current level of Atape device driver is available from: ftp://ftp.software.ibm.com/storage/devdrvr/AIX You should remove the older Atape driver before installing a newer level. To remove an older level of the Atape driver do the Atape command: /usr/lpp/Atape/lpp.deinst You should remove the RMT's that of the devices supported by Atape before installing a newer level of the Atape driver. To do this use the AIX command: rmdev -dl rmtx <-- where x is the device you wish to remove Do this for each of the RMT's associated with the device. The AIX command to install the Atape driver is: Diskette: installp -acXd /dev/rfd0 Atape.driver Directory: installp -acXd /pathname/filename Atape.driver Note: If after rebooting your system you see a defined device at the same address as the 7332-005 you may need to do an AIX command of rmdev -dl rmtx <--- where the x is the defined device to remove I may then be necessary to then do the AIX bosboot command, refer to your AIX documentation for information on the bosboot command. SCSD Tape/Optical Ucode Download Utility Genucode: Generic SCSI microcode download utility for SCSD devices Note: Do not power the tape drive off immediately after the microcode says it is complete as the tape drive is still doing internal processing that will take a few minutes to complete. On the 7205-311, wait until all LEDs stop flashing and the Green Open Door LED is the only LED on. Microcode installation instructions: You need to have "root" authority to run the Ucode download utility "genucode". Remove any tape from the drive. "genucode", "cpcat", "genucode.cat", "dsdata", and the microcode file must all be put in the /tmp directory. Use the following AIX command to change to the /tmp directory: cd /tmp Put "genucode", "cpcat", "genucode.cat", "dsdata", and the microcode file into the /tmp directory. Make sure the files "cpcat" and "genucode" are marked executable using the following AIX commands: chmod +x cpcat chmod +x genucode Run cpcat to copy "genucode.cat" to /usr/lpp/diagnostics/catalog/default This only needs to be done once per system. ./cpcat "dsdata" is the file name for the drive's specific data file used for customization of the download procedure. Use the "dsdata" file from the microcode package you downloaded. The binary microcode file must be in the form of VENDORNAME.FWLEVEL.LOADID as indicated in the "dsdata" file, such as: IBM-7205.V52.A0B00E24 The load id of the microcode file and the load id in the "dsdata" file must match the load id of the tape drive. The valid load ids are: 12GB 4mm Tape drive Single Ended Load ID is 00000101 White or Black Bezel 13GB 1/4" Tape drive Differential Load ID is A0B00E11 20GB 8mm Tape drive Single Ended Load ID is A0000001 White Bezel Differential Load ID is A0000002 Differential 7331-305 Load ID is A0000003 Single Ended Load ID is A0000004 Black Bezel 35GB DLT Tape drive Differential Load ID is A0B00E24 Run genucode to download the microcode to the tape drive: ./genucode -s rmt0 {rmt0 is Tape drive name} Note: Genucode will not prompt you before executing the download. It is NOT necessary to recycle (powering the OFF then ON) the system or the tape drive to have the tape drive microcode active. If you are going to recycle the system or the tape drive, MAKE SURE the microcode download IS COMPLETE. If the tape drive is recycled prior to the microcode download being complete, damage may be done to the internal programming of the drive requiring the drive to have to be replaced. If you try multiple microcode downloads to the drive without recycling the tape drive the microcode download may fail.
