Isolating Firmware Problems; Save Vfchost Map Data - IBM Flex System p270 Compute Node Installation And Service Manual

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 480.
3. Verify the system firmware levels. See "Verifying the system firmware levels" on page 18.
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 481.
v Check the RETAIN tips and code change history. If a firmware update is needed, see "Updating the
firmware" on page 16.
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
--------------- ---------------------------------------- ------- ---------- ------
vfchost1 U7895.42X.9999999-V1-C32
Status NOT_LOGGED_IN
FC name fcs1
Ports logged in 0
Flags 4<NOT_LOGGED>
VFC client name
Name Physloc
--------------- ---------------------------------------- ------- ---------- ------
vfchost2 U7895.42X.9999999-V1-C33
Status LOGGED_IN
FC name fcs0
Ports logged in 1
Flags a<LOGGED_IN,STRIP_MERGE>
VFC client name fcs1
In this example, the original serial number is represented as startSN.
