Isolating firmware problems
You can use this procedure to isolate firmware problems.
About this task
To isolate a firmware problem, follow the procedure until the problem is solved.
Procedure
1. If the compute node is operating, shut down the operating system. Use the CMM to perform a virtual
reseat. If the problem no longer occurs, no further action is necessary. You are finished with this
procedure.
2. Start the PERM image. See “Starting the PERM image” on page 494.
3. Verify the system firmware levels. See “Verifying the system firmware levels” on page 24.
4. Choose one of the following options:
v Remain on the current firmware level. See “Recovering the TEMP image from the PERM image” on
page 495.
v Check the RETAIN tips and code change history. If a firmware update is needed, see “Updating the
firmware” on page 22.
5. If the problem is not resolved, contact your next level of support.
Save vfchost map data
Before you replace physical components on your compute node, it might be necessary to first save the
original virtual Fibre Channel vfchost data of your compute node.
Procedure
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:
Name Physloc ClntID ClntName ClntOS
--------------- ---------------------------------------- ------- ---------- ------
vfchost1 U7895.42X.9999999-V1-C32 3
Status NOT_LOGGED_IN
FC name fcs1 FC loc code:U78AF.001.startSN-P1-C35-L1-T2
Ports logged in 0
Flags 4<NOT_LOGGED>
VFC client name VFC client DRC
Name Physloc ClntID ClntName ClntOS
--------------- ---------------------------------------- ------- ---------- ------
vfchost2 U7895.42X.9999999-V1-C33 4 cli_lpar_1 AIX
Status LOGGED_IN
FC name fcs0 FC loc code:U78AF.001.startSN-P1-C35-L1-T1
Ports logged in 1
Flags a<LOGGED_IN,STRIP_MERGE>
VFC client name fcs1 VFC client DRC:U9999.999.9999999-V4-C32-T1
In this example, the original serial number is represented as startSN.
