The pvkey (0 or 1 in this example) shown in the first command maps to the device file names
(/dev/dsk/c1t6d0 or /dev/dsk/c2t6d0) in the second command under columns PV1 and PV2,
respectively.
Step 5. Reduce any logical volumes that have mirror copies on the faulty disk drive so that they no longer
mirror onto that disk drive (note the -A n option):
# lvreduce -m 0 -A n -k <LV name> /dev/dsk/cXtXcX <pvkey#>& (for one-way mirroring)
OR
# lvreduce -m 1 -A n -k <LV name> /dev/dsk/cXtXcX <pvkey#>& (for two-way mirroring).
For example:
# lvreduce -m 0 -A n -k /dev/vg00/lvol4 /dev/dsk/c2t4d0 1&
The following message will appear:
Logical volume /dev/vg00/lvol4 has been successfully reduced.
lvlnboot: Logical Volume has no extents
It is important to include the ampersand (&) at the end of the command line. This lvreduce process
will hang, and you will need terminal control to kill the command. Once the "successfully reduced"
message has been generated, manually kill the process, using the kill -9 command.
a. Use the ps command to find the PID for the lvreduce process.
# ps -ef | grep lvreduce
b. Stop the process. (This may take several minutes before the process finally ends.
# kill -9 <PID>
Step 6. Repeat steps 4 and 5 for all logical volumes.
Step 7. With all logical volumes reduced, now reduce the volume group using the vgreduce command. For
example:
# vgreduce /dev/vg00 /dev/dsk/c2t6d0
