Isolating firmware problems
You can use this procedure to isolate firmware problems.
To isolate a firmware problem, follow the procedure until the problem is solved.
1.
If the blade server is operating, shut down the operating system and turn off the blade server.
2.
Turn on the blade server.
If the problem no longer occurs, no further action is necessary. You are finished with this procedure.
3.
If the blade server boots up far enough to allow the installation of server firmware updates, check for
appropriate updates and install them.
If you install updates, reboot the server and see if the problem still exists. If not, you are finished with
this procedure.
4.
Recover the system firmware, as described in “Recovering the system firmware” on page 220.
5.
After recovering the system firmware, check for and install any server firmware updates.
Save vfchost map data
Before you replace physical components on your blade server, it might be necessary to first save the
original virtual Fibre Channel vfchost data of your blade server.
To save the original vfchost data and the original physical Fibre Channel adapter port (fcs) location codes,
complete the following steps by using the
padmin
user account:
1.
To save the original vfchost data, use the
lsmap
command as follows. Enter the command from the
command-line interface on the source Virtual I/O Server (VIOS):
lsmap -all -npiv | tee lsmap_OUTPUT_before
The output might look like the following example:
