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. B-34 Service Guide
