Following is the instructions for updating the firmware (microcode) of the IBM RISC System/6000 SCSI-2 F/W PCI RAID Adapter. The installation of this firmware level is required. The file systems created on disks connecting to the adapter will be temporarily unavailable while the firmware is being updated.
Approximate time for microcode installation: 30 minutes
Before updating the adapter firmware, you must follow the instructions below to verify whether or not you have the appropriate level of adapter hardware and firmware in your system.
1) Issue the following command to list the PCI RAID adapters installed in the system:
lsdev -C | grep "scraid"
All installed SCSI-2 F/W PCI RAID adapters will be listed as available. The adapter device names will be in scraid# format, where # is the numeric logical identification of each adapter device.
2) To check the current microcode level for the adapter enter the following command
lscfg -vl scraid#
Note the FRU Number and the Loadable Microcode Level fields. If the FRU Number is either 07L9287 or 93H4902, and the Loadable Microcode Level is less than 97.348, the system contains the appropriate adapter hardware level and a down-level adapter firmware. You should update the adapter firmware.
If the FRU Number is 08L1319, the system does not contain the appropriate adapter hardware level. You should refer to Microcode Revision Level 98.150 FRU 08L1319 (Feature Code 2493).
Repeat these instructions for all SCSI-2 F/W PCI RAID adapters which need firmware update.
With the machine powered on and AIX operating system successfully loaded, follow the instructions below to install the FLASH code onto your SCSI-2 F/W PCI RAID adapters.
1) Log in as root
2) Type "cd /tmp".
3) Copy the file "scraid97348.bin" to "/tmp" in the Target Server.
4) Type "chmod +x scraid97348.bin"
5) Type "./scraid97348.bin" (note that ./ is necessary to extract the binary
file). This creates "/tmp/scraid97348" directory with the following files
: "2e1014C.97.348"
6) Type "cd /tmp/pciraid97348"
7) Type "cp 2e1014C.97.348 /etc/microcode/". This will copy the microcode image to the "/etc/microcode" directory.
8) You are now ready to FLASH the EEPROM in the adapter using the single command:
diag -c -d scraid# -T"download"
Where # is the number found from the "lsdev -C | grep scraid" command. Repeat the above command for all the cards that need the update.
