Attention:
administrator if a service partition has been designated.
v If it has, ask the customer or system administrator to shut down all of the partitions
except the one with service authority. The firmware update can then be done using
the service aid or the AIX command line in that partition.
v If a service partition has not been designated, the system must be shut down. If the
firmware update image is available on backup diskettes, the firmware update can
then be done from the service processor menus as a privileged user. If the firmware
update image is in a file on the system, the system should be rebooted in SMP mode
and the normal firmware update procedures outlined below followed.
If the system is already in SMP mode, the normal firmware update procedures outlined
below can be followed.
Note: This service aid runs on CHRP system units only.
This selection updates the system or service processor flash for CHRP system units.
Look for additional update and recovery instructions with the update kit. You need to
know the fully qualified path and file name of the flash update image file provided in the
kit. If the update image file is on a diskette, the service aid can list the files on the
diskette for selection. The diskette must be a valid backup format diskette.

determine the current level of the system unit or service processor flash memory.
When this service aid is run from online diagnostics, the flash update image file is
copied to the /var file system. If there is not enough space in the /var file system for the
new flash update image file, an error is reported. If this error occurs, exit the service
aid, increase the size of the /var file system, and retry the service aid. After the file is
copied, a screen requests confirmation before continuing with the flash update. When
you continue the update flash, the system reboots using the shutdown -u command.
The system does not return to the diagnostics, and the current flash image is not
saved. After the reboot, you can remove the /var/update_flash_image file.
When this service aid is run from standalone diagnostics, the flash update image file is
copied to the file system from diskette. The user must provide the image on a backup
format diskette because the user does not have access to remote file systems or any
other files that are on the system. If not enough space is available, an error is reported,
stating additional system memory is needed. After the file is copied, a screen requests
confirmation before continuing with the flash update. When you continue with the
update, the system reboots using the reboot -u command. You may receive a Caution:
some process(es) wouldn't die message during the reboot process, you can ignore
this message. The current flash image is not saved.
If the system is running in LPAR mode, ask the customer or system
