There are four image types which are transferred using the
lom -G
command:
■
lw8pci.flash
(contains I/O board Local POST)
■
lw8cpu.flash
(contains CPU/memory Board Local POST and OpenBoot
PROM)
■
sgsc.flash
(contains LOM/SC firmware)
■
sgrtos.flash
(contains LOM/SC Real-Time Operating System)
You must place these in a suitable directory, for instance
/var/tmp
, and issue the
lom -G
command with the appropriate filename for the respective hardware to be
updated. For example:
This command updates the CPU/memory board POST and OpenBoot PROM.
The firmware knows from header information contained in the file which image type
is being upgraded.
These images are provided in a patch downloadable from
www.sunsolve.sun.com
or from your Sun Service representative.
The patch README file should contain full instructions for installing these new
firmware images. It is very important that the instructions are followed exactly,
otherwise you might render your server unbootable.
