6.0.0 Microcode Download Procedure-SCSI Drives Attached to SCSI adapter

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?
AIX level 5.1 and above supports concurrent microcode download on all drives, including drives that are part of rootvg.
AIX level 4.33 and below does not support concurrent microcode download if drive is part of rootvg, microcode download can ONLY be performed in service mode(stand alone) using diagnostics CD. If disk is not part of rootvg, microcode download can be performed cuncurrently as long as drive is not in use.

Is system reboot needed to activate the microcode: Yes if stand alone diagnostics is used, NO if concurrent diagnostics is used.

Installation Time: Approximately 20 minutes/drive if stand alone diagnostics is used(using Diagnostics CD); Approximately 5 minutes/drive if consurrent diagnostics is used.

Procedure(AIX level 4.33 and below):
a- Online(Concurrent) Diagnostics(for drives that are not part of rootvg or paging space):
1. This step is optional.  Microcode download can be performed either from Diskette or from Disk.To copy files from the diskette to disk, place the diskette containing microcode files into diskette drive A, at AIX Prompt type   restore
2- At AIX prompt, type   diag
3. Select the "Task Selection" from diagnostics menu.

This procedure requires copying microcode files to the appropriate SPOT(s). Therefore, it is HIGHLY recommended that someone with an appropriate level of AIX experience and expertise should perform this task, preferably the System Administrator of person(s) designated as responsible for making software updates to the system.

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.
      (The current microcode level of the resource you selected earlier will be displayed at the top of the screen)
12.  In the "Select the input device" screen, make sure settings are as follows:

      Select Input Device --------------------------------------- [ disk]
      Microcode level to download ----------------------------- [ latest]
      Download latest level even if ------------------------------ [ yes]
      current is missing

PRESS "F7" to commit

13. You will receive a msg. "Current Microcode is" and "Download has completed successfully"
       (this may take a few minutes)

14. On CWS run the following command:
      spbootins -r disk [frame# [node#] [node count]

15. On CWS, After spbootins finishes, run the following command:
      splstdata -b (check output to see that node in question was set back to disk)

16. On "TTY" screen for node, Press F10 to get to "Shutdown Screen" and close TTY screen.
17. On perspectives screen of affected node, do a power off of the node and a power on of the node.
18. After node boots, telnet to the node, run the following command and check that correct microcode level has been updated.
          lscfg -vl hdisk# (ie hdisk0,hdisk1 etc).
