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.

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.

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
