README: DAT320 160/320 GB SAS Tape Drive Microcode
This package is being provided to allow the update of older DAT320 160/320 GB SAS Tape Drive Microcode Tape Drives to the latest level of microcode that is currently shipping from IBM.
Users are responsible install the latest microcode level.
The microcode and instructions are available
at the IBM external web site:
http://www.ibm.com/support/fixcentral
All levels of AIX that this product was announced on.
The typical time to install this microcode is .2 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.
In order to complete the microcode download to the tape drive
you will need to use the AIX diagnostics.
The AIX diagnostic package 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 Diagnostics.
Remove any tape cartridge from the drive prior to attempting the
microcode download.
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.
All pSeries systems 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 DAT320 160 GB tape drive
up to the current level of microcode which is:
VS12
| Tape Drive P/N | Tape Drive FRU P/N | Microcode Level | Load ID | Date Released | What does this microcode change
|
|---|---|---|---|---|---|
| 46C1932 | 46C1933 | VS07 | A1700D72 | Feb 15, 2010 |
|
| 46C1932 | 46C1933 | VS11 | A1700D72 | August 24, 2010 |

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 DAT320 160 GB tape drive do the following AIX command:
lscfg -vl rmt0 <--- change the drive number to reflect
the actual rmt address of the 160GB
DAT320 tape drive.
The output of the lscfg command will look like the following with the:
rmt0 U789C.001.DQDA282-P2-D1 SAS 4mm Tape Drive (160000 MB)
Manufacturer................IBM
Machine Type and Model......DDS Gen7
Device Specific.(Z1)........VS12
Serial Number...............20963003

Part Number.................46C1932
FRU Number..................46C1933
EC Level....................C70092

Device Specific.(Z3)........L1
Hardware Location Code......U789C.001.DQDA282-P2-D1
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 ./ before the command insures AIX paths thru the current directory to find the command.
To insure the file was downloaded without error do the following:
25041 1679 DDS_Gen7.A1700D72.VS12 29497 2 DDS_Gen7.A1700D72.dsdata
You need to determine how you are going to download the microcode:
AIX diagnostics naming and supported directory for the microcode and dsdata file.
Copy the Dsdata and Microcode files to appropriate directory for use by AIX diagnostics.
Note: The copy command copies the file to the new directory with the same name when you use the period(.) after new directory name.
If you downloaded the
RPM
file and executed it the microcode is in
the correct directory with the correct name for AIX diagnostic use.
If you downloaded the .bin
file and executed it then you need to do
the following AIX commands:
cd /tmp/DAT320_web
cp DDS_Gen7.A1700D72.dsdata /etc/microcode/.
cp DDS_Gen7.A1700D72.VS12 /etc/microcode/.
There are 2 ways to do the microcode download using the AIX diagnostics.
To use the AIX Diagnostics menu for microcode download do the following:
Note: There are differences between AIX levels of AIX Diagnostics.
In some cases the step after Task selection is Microcode Tools, or
Download Microcode. The following steps are general instructions to
download microcode.
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
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 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.
Note: If the microcode download fails install:
