README: 7207-012 1.2GB 1/4" Tape Drive Microcode
This package is being provided to allow the update of older IBM 7207-012 1.2GB 1/4" Tape Drives to the latest level of microcode that is currently shipping from IBM.
You are encouraged to install the latest microcode level
yourself. The microcode and instructions are available for
your use 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.
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.

To determine if your machine(s) has one of these level tape
drives, type the command on an AIX prompt:
lscfg -vl rmt* | pg
* The "*" will show the Vital Product Data for all tape drives that are in the available state.
The output of the command have the combined Z1 and Z2 fields showing
the microcode level of the drive.

There are 2 different microcode files because
there are 2 levels of the drive in the field.
The 2 different levels of the drive are due to
Engineering Changes(EC)to the internal drive components.
AIX uses the "Load ID" of the tape
drive to determine which microcode goes to which EC level of the tape
drive.
The "Load ID" of this tape drive
cannot be seen by the user with standard AIX commands.
There are 2 ways a you can get the microcode files. Each of these will put the microcode on your system but the you may have to move the files to appropriate directory for system use.
When you download 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 your AIX permission does not allow the copy to the above stated
directory or file then you will be prompted for a new location.
AIX diagnostics requires the microcode files to be in the
/etc/microcode
directory. You must copy the files
from the
/tmp/7207012_web
directory to the
/etc/microcode
directory using the AIX commands:
cd /tmp/7207012_web
cp IBM-4100.A0B00E10.0932 /etc/microcode/.
cp IBM-4100.A0B00E13.0932 /etc/microcode/.
Note: The copy command copies the file to the new directory with the same name when you use the period(.) after new directory name.
To verify the microcode do the following and compare the output of
sum
command:
cd /etc/microcode
sum IBM-4*
22071 129 IBM-4100.A0B00E10.0932
60255 129 IBM-4100.A0B00E13.0932
If your output does not match what is shown here, repeat the process you did to download and expand the files insuring that the binary files are loaded correctly.
Note:
Previously installed microcode not on the system.
The AIX diagnostics will look for earlier versions of microcode for the
device you chose for the install. If you see the message from the AIX
diagnostics about download microcode without the previous level present
reply to the prompt to continue with the install even though the
previous level of microcode is not available on the system.
To start the install enter the following AIX command:
diag
Select Service Aids
Select Microcode Download
Follow the instructions.
To have the tape drive VPD data show the current level of microcode
just installed in the drive do the following AIX commands:
rmdev -l rmtx <--where x is the drive number
mkdev -l rmtx <--where x is the drive number
