README: IBM 7332-220 4mm Autoloader Microcode
This package is being provided to allow the update of older IBM 7332-220 4mm Autoloader 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 .4 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, or the Atape program.
If the system does not have the AIX 5.1, or later, diagnostics you will
need to get the Genucode package or the Atape program. Genucode is
available from the IBM external web site:
download.html
The Atape program was shipped with the IBM 7332-220.
It is also available from the web:
ftp://ftp.software.ibm.com/storage/devdrvr/AIX
For the AIX diagnostic package or for Genucode, or for Atape, 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
or Atape 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.
It is normal for this autoloader's AMBER LED to flash during 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 7332-220 4mm tape drive
up to the current level of microcode which is:
H211
| Tape Drive P/N | Tape Drive FRU P/N | Load ID | Microcode Level | What does this microcode change
|
|---|---|---|---|---|
| 35L1170 | 35L1199 | 00000202 | H003 | First Microcode level shipped.
|
| 35L1170 | 35L1199 | A1700293 | H008 | Sets time for cleaning indication to 50 hours.
Fixes cases of variable block read failure. Sets default blocksize of 512. Note: The H008 level of microcode changes the default blocksize to 512 instead of the default of 1024. If the AIX command rmdev -dl rmt0 is used to logically remove this drive then the drive is added back to the system the default block size will be set to 512 instead of the 1024 block size. The CE and customer must verify the default blocksize is correct for the customer.
|
| 35L1170 | 35L1199 | A1700293 | H210 | Sets default blocksize of 1024.
SCSI Parallel Protocol Request related fixes. Removal of the 50 usage limit on DDS2 test tapes. Fixed handing of large number of appending of data causing subsequent space commands over the appended data to fail with an indication of media format corrupted(Sense Key 03, ASC/ASCQ 3100).
|
| 35L1170 | 35L1199 | A1700293 | H211 | Eliminates SCSI error message on the drive LCD when the drive is
powered on with some newer SCSI adapters.
|
Note: In some cases you may already have the most current level of microcode already installed. The following instructions show you how to check the tape drive microcode level.
To display the level of microcode in the IBM 7332-220
4mm tape drive do the following AIX command:
lscfg -vl rmt0 <--- change the drive number to reflect
the actual rmt address of the
IBM 7332-220 4mm tape drive.
The output of the lscfg command will look like the following with
the
"Device Specific.(Z1)" showing the microcode level:
rmt0 00-00-01-2,0 7332 4mm Auto Loader SCSI Tape Device
Manufacturer................HP
Machine Type and Model......IBM-C571303030
Part Number.................35L1170
EC Level....................D19416
FRU Number..................35L1199
Device Specific.(Z1)........H003
Device Specific.(Z0)........0180
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.
Note: The last eight(8) digits of the microcode file name are the
autoloader load id. Prior to the
H008 level of microcode the load id of
the autoloader was:
00000202
With install of the
H008, or higher, level of microcode the load id
is:
A1700293
Both AIX diagnostics and Genucode look at the load id of the drive and
compare it to the load id in the dsdata file and microcode file. Because
of this you have to use one pair of
dsdata file and microcode files for drives
with a microcode level below H008 and another pair for drives with a
microcode level of H008 and above.
To insure the microcode restored correctly do the AIX command
sum on
the microcode file and compare it to the following:
sum IBM*
50665 335 IBM-C571303030.H211.00000202
50665 335 IBM-C571303030.H211.A1700293
You now will need to determine if the Atape device driver is
installed.
To determine if the Atape device driver is installed do the following
AIX command:
lslpp -l Atape.driver
This will show the level of the Atape driver if it is installed. If the Atape device driver is installed skip to the step "Install with Atape".
If the Atape device driver is not installed you now need to use the AIX diagnostics or the instructions in the Genucode package to complete the microcode install process.
AIX 5.1 diagnostics must have a minimum PTF/APAR
level of:
PTF# U477173 and APAR# IY27025.
As of February 15, 2002:
The current level of AIX Diagnostics CDROM 5.1.0.15 does NOT
contain the fixes required to do microcode download to SCSD drives.
The fix required to do microcode download to SCSD drives will be in the
next release of Diagnostic CD when they are announced and released.
To use AIX 5.1 diagnostics with the tape drive microcode use
different naming
conventions and the files must be in the
/etc/microcode
directory.
Do the following AIX commands to copy the files with the
proper naming conventions:
cd /etc/microcode
cp /tmp/7332220_web/dsdata IBM-C571303030.00000202.dsdata
cp /tmp/7332220_web/dsdata.current IBM-C571303030.A1700293.dsdata
cp /tmp/7332220_web/IBM-C571303030.H211.00000202 IBM-C571303030.00000202.H211
cp /tmp/7332220_web/IBM-C571303030.H211.00000202 IBM-C571303030.A1700293.H211
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)
Determine the current level of microcode in the tape drive
is H003 if it is do the following AIX commands:
cd /tmp/7332220_web
cp dsdata /tmp/dsdata
cp IBM-C571303030.H211.00000202 /tmp/IBM-C571303030.H211.00000202
To complete the microcode install follow the instructions in the Genucode package.
Determine the current level of microcode in the tape drive
is H008 or higher, if it is do the following AIX commands:
cd /tmp/7332220_web
cp dsdata.current /tmp/dsdata
cp IBM-C571303030.H211.00000202 /tmp/IBM-C571303030.H211.A1700293
To complete the microcode install follow the instructions in the Genucode package.
You now need to issue the Atape tapeutil command:
tapeutil
Then select Autoloader Service Aids
Then select Microcode load
Then select the tape drive you are going to download microcode
to.
Then enter the file name of the microcode file you are going to
use for the download:
/tmp/7332220_web/IBM-C571303030.H211.00000202
