6.0.0 Microcode Download Procedure-SCSI Drives Attached to SCSI adapter

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

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

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?
If the disk is part of rootvg, microcode download can ONLY be performed in service mode 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

Installation Time: Approximately 20 minutes if drive is part of rootvg(using Diagnostics CD); Approximately 5 minutes/drive if drive is not part of rootvg(using concurrent diagnostics).

Procedure:
1. Properly shutdown the system.
2. Boot up the system in SERVICE mode with the CDROM diagnostics(Use diagnostics level 4.21 or above;  It is recommended to use the same level of
    Diagnostic CD as the AIX ).
3. Select the "Task Selection" from diagnostics menu.
4. Select "Microcode Download" from "Task Selection" menu.
5. Select resource that microcode will be applied to(hdisk?) and PRESS ENTER.
6. Press "F7" to commit.
      (The current microcode level of the resource you selected earlier will be displayed at the top of the screen)
7. Make the following selections on the next screen:
    Select Input Device --------------------------------------- [ diskette]
    Microcode level to download ----------------------------- [ latest]
    Download latest level even if ------------------------------ [ yes]
    current is missing

NOTE: A prompt will ask you to insert the microcode diskette into the floppy drive. Insert the diskette which accompanies these instructions. If this level is already installed in the drive you've selected a message will let you know. A message will also come up because the diskette does not have the previous level microcode on the diskette. This is true and is not required to complete the download.
PRESS "F7" to commit

8. You will receive a msg. "Current Microcode is" and "Download has completed successfully"
       (this may take a few minutes)
9. Return to the Tasks Selection menu and repeat this procedure for each hard disk that requires this microcode.
10. Exit diagnostic and reboot system in normal mode.

11. Exit diagnostic and reboot system.
 

6.0.2 Microcode Download Procedure-SP systems

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

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 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)
