7.7.2 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.
Refer also to 6.7.4.4, “How to Perform the SMS Firmware Update” on page
182 and the README file that comes with the firmware update.
7.7.3 Updating Firmware from the Service Aids
Note: This service aid is only supported for On-line Diagnostics.
This service aid allows you to update the system or service processor flash.
Additional update and recovery instructions may be provided. You also 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 does
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 asks for confirmation to continue the flash
update. Continuing the flash update eventually causes 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.
7.7.4 Updating Firmware from AIX
You must delete the file /var/update_flash_image before proceeding.
The flash update image file must have already been placed in the /var file
system. This could have been done with a file transfer from another server or
with the dosread command of the AIX DOS Utilities, for example. With the
flash update image in place, issuing the following AIX command
shutdown -u
/var/
<filename>
\.img initiates the update process. Where
<filename>
is the
name of the flash update image. During the process, the server powers down
