UPDATE_FLASH(8) Linux on Power Service Tools UPDATE_FLASH(8)NAMEupdate_flash - manage system and service processor firmware
SYNOPSIS
/usr/sbin/update_flash [-v] -f firmware.img
/usr/sbin/update_flash -c
/usr/sbin/update_flash -r
DESCRIPTION
The update_flash script is used to update, manage, and validate
firmware on an IBM ppc64 system.
When used with only the -f option and an image file name, the script
will attempt to update the system firmware with the given image. If
the machine has the ability to pre-validate the image, this will be
done automatically before the flash. If the machine is not capable of
pre-validation, or if validation passes, this script will upload the
firmware image into the kernel and will perform a shutdown -r now which
will reboot the system. The flash will occur at the end of the reboot.
WARNING: The system WILL be rebooted! Wait until the flash process has
completed. This can be anywhere from 2 minutes to 20 minutes (or more)
depending on the system. The op panel display will show that the sys‐
tem is flashing. Failure to wait may render a system inoperable.
When used with the -v option, the script will ONLY perform validation
of the image file. Regardless of the outcome of the validation, no
actual flash will occur. This option is only useful on machines that
support validation of firmware images.
When used with the -c option, the script will commit the temporary
image to the permanant side. In order to use this, the machine must be
running on the temporary image. This option is only useful on machines
supporting two firmware image areas.
When used with the -r option, the script will reject the temporary
image. In order to use this, the machine must be running on the per‐
manant image. This option is only useful on machines supporting two
firmware image areas.
OPTIONS-f filename
Supply the filename to flash (required).
-v Validate ONLY with specified image file.
-c Commit temporary image to permanant side.
-r Reject temporary image.
EXAMPLE
Firmware may be downloaded from the IBM website if a problem is encoun‐
tered that requires a firmware update. If the firmware comes with
instructions for Linux please follow those instructions as they are
more up-to-date than this page.
Download the firmware image in AIX format. The file will have a .BIN
extension. This zip file happens to be an AIX binary, but it can be
extracted with the unzip command (with password from the web page):
unzip 70286C4F.BIN
This should produce a file with a .img extension. This image file is
what should be flashed:
update_flash-f RR021024.img
FILES
rtas_flash kernel module
