Page: 312 / 358

Refer to the downloaded update instructions, or to the System Management Services
“Config” on page 5-5 or “Display Configuration” on page 5-26 or Service Processor
menus on page B-7, to determine the level of the system unit or service processor
flash.
Updating Firmware from the Service Processor Menus:
The Service Processor Menus
are available while the server is powered off. From the Service Processor Main
Menu, select Service Processor Setup to bring up a menu containing the item,
Reprogram Service Processor Flash EPROM. Selecting that item starts the update
process. The process requests the update diskette(s) as needed. After inserting the
first diskette and informing the system, the process continues automatically. If the
process requires user assistance, it is requested.
Updating Firmware from the SMS Utilities:
From a powered down or reset condition,
bring up the SMS Utilities and select the menu item for updating firmware. The
process requests the update diskette(s) as needed. After inserting the first diskette
and informing the system, the process continues automatically. If the process
requires user assistance, it is requested.
Updating Firmware from the Service Aids
Note: This service aid is only supported for Online Diagnostics.
:
This service aid
allows you to update the system or service processor flash.
Additional update and recovery instructions may be provided; also you need to know
the fully qualified path and file name of the flash update image file. If the flash
update image file is on a diskette, you need the AIX DOS utilities package to process
the diskette. You can use the dosdir command to find out the name of the update
image file. This service aid uses the dosread command to put the file into the /var
file system.
Using this service aid to update the system or service processor flash will not save
the current contents of the flash.
The flash image file will be copied in the /var file system. If there is not enough
space in the /var file system for the flash update image file, an error is reported. If
this occurs, exit the service aid, increase the size of the /var file system and retry the
service aid. After the file is copied, a warning screen will ask for confirmation to
continue the flash update. Continuing the flash update will eventually cause the
system to reboot and return to the AIX login prompt. After the system unit reboots,
the file /var/update_flash_image can be removed to conserve space in the /var file
system.
