README: 60GB 8mm Tape Drive Microcode
This package is being provided to allow the update of older IBM 60GB 8mm Tape Drives to the latest level of microcode that is currently shipping from IBM.
Customers are encouraged to install the latest microcode level
themselves. The microcode and instructions are available
at the IBM external web site:
download.html
All levels of AIX that this product was announced on.
The typical time to install this microcode is .5 hrs.
The microcode becomes active when installed and does not require a
system reboot to become active.
Yes, but the tape drive must be available with no tape in the drive, and no other processing running to the tape drive.
A reboot is not needed as the microcode is active in the drive when the drive completes microcode download. But to have the Vital Product Data show the new level you must use the AIX rmdev and mkdev commands.
In order to complete the microcode download to the tape drive
you will need to use the AIX 5.1 diagnostics and higher, or the
Genucode program.
If the system does not have the AIX 5.1, or later, diagnostics you will
need to get the Genucode package from the WEB.
For both the AIX diagnostic package or for Genucode you will
need the microcode and dsdata files in this
package.
This tape drive package will get you to step where
you will need to use the AIX 5.1 and higher Diagnostics or Genucode
to download the microcode into the tape drive.
Do not power off the tape drive during microcode download as this may damage the tape drive microcode requiring the tape drive to be replaced.
Remove any tape cartridge from the drive prior to attempting the microcode download.
All pSeries and RS/6000 machines this product was announce on. In general if the tape drive configures and is available with the VPD showing the Machine Type and microcode level as described in this README the machine is one affected.
The microcode update will bring the IBM 60GB 8mm tape drive
up to the current level which is:
07wR
| Tape Drive P/N | Tape Drive FRU P/N | Microcode Level | Load ID | What does this microcode change
|
|---|---|---|---|---|
| 19P0692 | 19P0708 | 02pR | A1700295 | First Microcode level shipped.
|
| 19P0692 | 19P0708 | 02sR | A1700295 | Fixes failure on diagnostics when diagnostics was run multiple times.
Changes the time for the "Clean Soon" message and the Cleaning Amber LED coming on from 140 tape motion hours to 100. Adds message to messages displayed "Worn Tape"(a tape that exceeds 20,000 passes over any one spot on the tape).
|
| 19P0692 | 19P0708 | 03cR | A1700295 | Fixes one cause of Tape_Err2(Fault Symptom Code 8C)
Machine type changes from IBM-60GB to Mammoth2
|
| 19P0692 | 19P0708 | 03nR | A1700295 | Fixes one cause of Tape_Err2(Fault Symptom Code 8C).
|
| 19P0692 | 19P0708 | 03rR | A1700295 | Improves Mammoth2(60GB 8mm) read time of Mammoth1(20GB 8mm) written
tapes.
|
| 19P0692 | 19P0708 | 03sR | A1700295 | Fixes one cause of Tape_Err2(Fault Symptom Code 8C).
Fixes AIX diagnostics indicating a drive failure when the tape drive was tested under AIX diagnostics and the diagnostic test was done without using the test tape.
|
| 19P0692 | 19P0708 | 07nR | A1700295 | Time between cleanings now 30 tape motion hours.
Drive will now eject tape if the tape path internally in the drive exceeds 47 degrees C. The drive will display a message indicating "OVER TEMP". Improved reading of Mammoth 1 written tapes. Fixes several causes of Tape_Err2(Fault Symptom Code 8C).
|
| 19P0692 | 19P0708 | 07pR | A1700295 | Change some Mammoth1 media errors sense data to properly indicate a
media error
(sense key 03) instead of a hardware error(sense key 04).
Improved rejection of unsupported tape cartridges(VXA). Improved end of tape handling on 22m Mammoth1 tape cartridges.
|
| 19P0692 | 19P0708 | 07uR | A1700295 | Changed some sense data error reporting on Read/Write errors to
more correctly report the type of failure.
Use "Active Negation" when the tape drive operates in Single Ended(SE) mode. This may reduce the chance of SCSI errors on very active SCSI busses. Corrected some causes of Fault Symptom Code(FSC) "8C", Controller firmware logic error, involving SmartClean.
|
| 19P0692 | 19P0708 | 07wR | A1700295 | Improves the tape buffer handling when data is in the compressed mode.
A reliability improvement when data compression is enabled (changes to
the code decrease the number of start/stops resulting in less stress on
the reel servo mechanism and on tape).

Note: In some cases you may already have this microcode update already installed. The following instructions show you how to check the tape drive microcode level.
To display the level of microcode in the 60GB 8mm tape drive do the
following AIX command:
lscfg -vl rmt0 <--- change the drive number to reflect
the actual rmt address of the 60GB
8mm tape drive.
The output of the lscfg command will look like one of
the following with the
"Device Specific.(Z1)" showing the microcode level:

The Machine Type and Model change from IBM-60GB to Mammoth2
starting with the 03cR level of microcode.
Machine Type and Model......Mammoth2
If the Machine Type and Model do not show Mammoth2 it will be necessary to do two(2) microcode downloads to the tape drive. This is necessary because AIX Diagnostics and Genucode check the Machine Type and Model as part of the verification for microcode download to the tape drive.
To determine which microcode file must be installed do the following:
Issue the AIX command:
lscfg -vl rmt0
Manufacturer................EXABYTE
Machine Type and Model......IBM-60GB
Device Specific.(Z1)........02pR
Serial Number...............62019643

If the Machine Type and Model has IBM-60GB
then it is necessary to install both:
microcode file
If the Machine Type and Model has Mammoth2
then it is only necessary to install only:
microcode file
There are 2 ways a user can get the microcode files. Each of these will put the microcode on the user's system but the user may have to move the files to appropriate directory for system use.
When the user downloads the microcode files from the IBM web site the packaged microcode files will be put into the /tmp directory.
Note:
AIX commands and file names are case sensitive.
If the users AIX permission does not allow the copy to the above stated
directory or file then the user will be prompted for a new location.
To insure the file was downloaded without error do the following:
To update the microcode using the AIX diagnostics it is necessary to copy the files to the /etc/microcode directory as AIX diagnostics only looks for microcode in the /etc/microcode directory.
For instructions on using the AIX Diagnostics microcode download
refer to the section of this README titled
"How to Use AIX 5.1 Diagnostics Microcode Download".
If the RPM method was not used then it is necessary for you to
copy the files to the /etc/microcode directory.
The /. (slash dot) in the following commands uses the input name for the
output name of the file.
Use the following AIX commands to copy the files to the
/etc/microcode
directory:
cd /tmp/60GB8mm_web
cp Mammoth2.A1700295.dsdata /etc/microcode/.
cp Mammoth2.A1700295.07wR /etc/microcode/.
To install both microcode files use the following instructions:
If the tape drive Machine Type and Model already is Mammoth2 then it is necessary to install only the new Mammoth 2 microcode file.
The dsdata file for the IBM-60GB and Mammoth2 microcode files are unique to each microcode file, it is necessary to copy the particular microcode file and its associated dsdata file to the /tmp directory just prior to running genucode for that microcode file.
If the tape drive
Machine Type and Model
already is
Mammoth2
then it is only necessary to install the new microcode file.
There are 2 ways to do the microcode download using the AIX diagnostics.
To use the AIX 5.1 diagnostics menu for microcode download do the
following:
diag (enter)
Task Selection (enter)
Download Microcode (enter)
Select the drive you wish to download microcode to and follow the system instructions.
Note: When the system asks where the microcode file is to be found select /etc/microcode, not diskette.
The command line to download microcode will use the highest level of microcode in the /etc/microcode directory for the device selected. To use the AIX 5.1 diagnostics command line input for microcode download do the following:
Note: If the previous level of microcode is not in the /etc/microcode
directory you will need to use the
-f
option(force) as the diagnostics
expect the previous level to be present in the /etc/microcode directory.
diag -c -d rmt0 -T "download" (enter)
or
diag -c -d rmt0 -T "download -f" (enter)
