2.0 General Information & History
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.

3.0 Identifying the Drive and Current Microcode
Level
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
CDROM drive.
The
output of the command will look like this:
DEVICE LOCATION DESCRIPTION
cd0 00-04-00-3,0 16 Bit SCSI Multimedia CDROM Drive
(650 MB)
Manufacturer................IBM
Machine Type and Model......CDRM00203
ROS Level and ID............1_06 <-- This is the microcode level
currently in the drive
Device Specific.(Z0)........058002028F000038
Part Number.................04N2964 <-- The part numbers are listed “Drives affected”
section that the user should be looking for.
EC Level....................F73113
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.

Microcode Download Procedure
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.
- The user should download the 40xcdrom.bin file
from the web, and place it in the /tmp directory. The following AIX commands will expand
the files:
- cd /tmp
- chmod +x 40xcdrom.bin
- /tmp/40xcdrom.bin (password is case-sensitive:
**RS/6000**)
- This puts the following files in the /tmp/40x_web directory:
- 40x.readme
- IBM_____CDROM00203.06.0 (underline create with 5 underscores)
- dsdata
- If the CD-ROM process is used to put the microcode onto
the system, the /microcode/CDROM_40
directory will have the files for the 40x CDROM DRIVE
- If the 40xcdrom.bin
is present, then follow directions in the IBM WEB process. If it is not present, then follow these
steps.
- mkdir
/tmp/40x_web
- cp /mnt/microcode/CDROM_40/40x.readme /tmp/40x_web (this
example is with the CD-ROM mounted in the mnt directory)
- cp
/mnt/microcode/CDROM_40/IBM_____CDROM00203.06.0 /tmp/40x_web (underline is create with 5
underscores)
- cp
/mnt/microcode/CDROM_40/dsdata /tmp/40x_web
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.
After Genucode Utility is installed, then the user must move
the microcode and dsdata file into the /tmp directory.
cd /tmp
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.
- Genucode will
use the DSDATA file and the microcode file.
- There are
several ways to run genucode but the simplest is to use the command line
form detailed next. Be aware the command line form will not prompt the
user before executing. Issue the following command, from the /tmp
directory to update the drive microcode:
./genucode -s cd0
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..
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.
Note: The AIX
commands require Root authorization and are:
rmdev -l cd0
mkdev -l cd0
lscfg -vl cd0
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..
