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/ᑍfilenameᑍ.img initiates the update process. Where *filename* is the name of the flash update image. During the process, the server powers down and reboots. You know the process is complete when the login prompt reappears.
