Warning: Do not power off the system or the drive during microcode download as this may permanently damage the disk drive

NOTE: Please save current and older versions of the microcode update files in case you need to restore your system.

Caution: The microcode download process is nondestructive to the hard disks; however, as a precaution, ensure that a backup operation has been performed on the affected systems PRIOR to the microcode installation.

Can microcode be installed Concurrently?
 NO. If the disk is part of rootvg or used as a paging device, microcode download can ONLY be performed while node is "Network Booted" into "Diagnostic Standalone Mode".

Is system reboot needed to activate the microcode: Yes

Installation Time: Installation time will vary depending upon the system configuration

Procedure for SP System (Nodes):

Note: Make sure that node on which work is to be performed has been "fenced" from the switch.
1. Obtain proper microcode diskette from from your IBM Service Representative.
2. Copy microcode file from diskette onto CWS:
     restore -xvq
     (file will be copied into the "etc/microcode" directory)

3. Move microcode file from "etc/microcode" directory to the appropriate Spot(s) that are used by the customer for the node(s) to be updated.
    ie: /spdata/sys1/install/aix4??/spot/spot_aix4??/usr/lib/microcode                (??= level of AIX on your system)

4. To set the Node(s) to boot from network, from CWS, run command:
    spbootins -r diag [frame#] [node#] [node count]
    (example - - spbootins -r diag 1 13 1)

5. From Perspectives, perform a "Shutdown" for the node(s) to be updated.
6. From perspectives screen for node to be updated, select "Network Boot" and wait for TTY to open to DIAG MENU.
7. Choose "Task Selection".
8. Choose your terminal type.
9. Select "Download Microcode"
10. Select resource that microcode will be applied to(hdisk?) and PRESS ENTER.
11. Press "F7" to commit.
