Drive P/N FRU P/N Description
04N2964 04N2967 16 Bit SCSI Multimedia CD-ROM Drive
04N2964 97H7796 16 Bit SCSI Multimedia CD-ROM Drive
40X Microcode information for the internal 40X and the external IBM 7010-020. Current microcode level is 1_06.
This package is being provided to allow the update of older IBM 40X CDROM Drives to the current level of microcode that is currently shipping from IBM.
Resolves B80 Slow Boot problem
Resolves CD boot hang on M80, H80
Will allow to Boot off of a CD
Production Level microcode
To display the level of microcode in the 40X CDROM drive perform the following AIX command:
lscfg -vl cd0 <--- change the drive number to reflect>
the actual cd address of the 40X
The output of the command will look like this:
DEVICE LOCATION DESCRIPTION
0 16 Bit SCSI Multimedia CDROM Drive
Machine Type and Model......CDRM00203
ROS Level and ID............1_06 <-- This is the microcode level
currently in the drive
Part Number.................04N2964 <-- The part numbers are listed “Drives affected”
section that the user should be looking for.
FRU Number..................97H7796 (previous FRU was 04N2967)
The fields pointed at with an arrow and listed in bold are the fields the user needs to look at to determine if they are updating the correct drive.
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 will 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 should 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.
Follow the directions on the WEB (http://www14.software.ibm.com/webapp/set2/firmware/gjsn?mode=20&page=genucode.html) or CD to upload and install the Genucode Utility onto your system. The Genucode Utility can be found on the web at http://www14.software.ibm.com/webapp/set2/firmware/gjsn?mode=9&type=media under the heading of"1 Genucode: Generic SCSI microcode download utility for SCSD devices".
After Genucode Utility is installed, then the user must move the
microcode and dsdata file into the /tmp directory.
cp /tmp/40x_web/dsdata /tmp
cp /tmp/40x_web/IBM_____CDROM00203.06.0 /tmp (underline is created with 5 underscores)
Note: Do not power the drive off immediately after the microcode says it is complete as the drive may be still doing internal processing that will take a few minutes to complete.
If the drive has
just been powered on and no other AIX commands have been issued to the drive genucode may indicate a failure to download the microcode.
The workaround to this is to retry the microcode download.
If genucode returns an error on completion, retry the command as this may clear the error condition.
Note: The previous command is dot(.) slash(/) to insure the command executed is the command in the /tmp directory as some systems do not look for the command to be executed in the current directory.
After installing the microcode issue the following AIX commands to remove the device from the AIX configuration then add it back.
Where the cd0 is the drive to be updated. If the drive is other than cd0, change the name to the appropriate drive name, such as cd1 or cd2, etc..
