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.
2. To save the location code information for each Fibre Channel adapter (fcs), enter the lsdev command
as follows:
lsdev -vpd | grep fcs | tee LSDEV_OUTPUT_before
The output might look like the following example:
fcs0 U78AF.001.startSN-P1-C35-L1-T1 Dual Port 8Gb FC Mezzanine Card (7710322577107501)
fcs1 U78AF.001.startSN-P1-C35-L1-T2 Dual Port 8Gb FC Mezzanine Card (7710322577107501)
In this example, the original serial number is represented as startSN.
