microcode image on the NIM server. After performing the NIM boot of diagnostics one
can use this service aid to update the microcode from the NIM server by choosing the
/usr/lib/microcode directory when prompted for the source of the microcode that you
want to update. If not enough space is available, an error is reported, stating additional
system memory is needed. After the file is copied, a screen requests confirmation
before continuing with the flash update. When you continue with the update, the system
reboots using the reboot -u command. You may receive a Caution: some process(es)
wouldnt die message during the reboot process, you can ignore this message. The
current flash image is not saved.

located in the /usr/lpp/diagnostics/bin directory. The command syntax is as follows:
update_flash [-q] -f file_name
update_flash [-q] -D device_name -f file_name
update_flash [-q] -D update_flash [-q] -D device_name -l
Flag Description
-D Specifies that the flash update image file is on diskette. The
device_name
variable specifies the diskette drive. The default
device_name
is /dev/fd0.
-f Flash update image file source. The
file_name
variable specifies the fully
qualified path of the flash update image file.
-l Lists the files on a diskette, from which the user can choose a flash update
image file.
-q Forces the update_flash command to update the flash EPROM and reboot
the system without asking for confirmation.
Attention: The update_flash command reboots the entire system. Do not use this
command if more than one user is logged on to the system.
