Update system or service processor flash (CHRP)

This selection, located in the Microcode Tasks submenu, updates the system or service processor flash for CHRP system units.

Further update and recovery instructions may be provided with the update. It is necessary to know the fully qualified path and file name of the flash update image file that was provided. If the flash update image file is on a diskette, the Service Aid can list the files on the diskette for selection.

When run from online diagnostics, the flash update image file is copied to 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 update flash. Continuing the update flash reboots the system. The system does not return to diagnostics. The current flash image is not saved. After the reboot, the /var/update_flash_image can be removed.

When running from standalone diagnostics, the flash update image file is copied to the file system from diskette. The user needs to provide the image on a diskette since the user does not have access to remote file systems or any other files that are on the system. If enough space is not available, an error is reported stating additional system memory is needed. After the file is copied, a warning screen asks for confirmation to continue the update flash. Continuing the update flash reboots the system. The current flash image is not saved.

The update_flash command can be used in place of this Service Aid. It is located in the /usr/lpp/diagnostics/bin directory.
