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 .
Restore vfchost map data
After you replace physical components on your blade server, you must review the virtual Fibre Channel
vfchost mapping. If the vfchost mapping has changed after component replacement, you must restore the
mapping.
To restore vfchost data, you must have first saved the original vfchost data and the physical Fibre
Channel adapter (fcs) location code information. For information, see “Save vfchost map data” on page
218.
To restore the vfchost mapping data, use the third field of the Fibre Channel adapter (fcs) location codes,
which is the serial number field, and compare the new Fibre Channel adapter (fcs) location codes to the
original location codes. Perform a
vfcmap of the new Fibre Channel adapter (fcs) to the appropriate
vfchost.
To restore the vfchost mapping data, complete the following steps by using the
padmin
user account:
1. To save the new Fibre Channel adapter (fcs) location codes, use the
lsdev –vpd
command as follows.
Enter the command from the command-line interface on the source Virtual I/O Server (VIOS):
lsdev -vpd | grep fcs | tee LSDEV_OUTPUT_after1
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)
2. To associate the new fcs x adapter to the old fcs x adapter use the adapter slot number. Enter the
grep
command as shown in the example below:
grep "P1-C35-L1-T1" LSDEV_OUTPUT_before LSDEV_OUTPUT_after
The output might look like the following example:
LSDEV_OUTPUT_before:
fcs0 U78AF.001.startSN-P1-C35-L1-T1 Dual Port 8Gb FC Mezzanine Card (7710322577107501)
LSDEV_OUTPUT_after1:
fcs0 U78AF.001.newSN99-P1-C35-L1-T1 Dual Port 8Gb FC Mezzanine Card (7710322577107501)
In this example, the original serial number is represented as
startSN
, the new serial number is
represented as
newSN99
, and the fcs x remained fcs0; therefore, fcs0 will be mapped to the vfchost.
3. To restore the new fcs x device to the correct vfchost, enter the
vfcmap
command as follows:
vfcmap -vadapter vfchost0 -fcp fcs0
