Step 6 
Use the 
lvextend
 command to transfer the mirrors back on to the replaced disk. This will take some 
time because it copies all of the data from the original copy of the data to the mirrored extents. The logical 
volumes are still accessible to users’ applications during this command for two-way mirroring: 
# lvextend -m <one greater than num_mirror> <LV name> physical volume path 
or for three-way mirroring: 
# lvextend -m <one greater than num_mirrors> <LV name> physical volume path 
If you follow the example under “Example of a Disk Module Failure”, the host will display: 
# lvextend -m <one greater than num_mirrors> /dev/vg00/lvol4 /dev/dsk/c2t4d0 
# lvextend -m <one greater than num_mirrors> /dev/vg00/lvol5 /dev/dsk/c2t4d0 
At this point, your system should be fully functioning. 
If the host fails during Step 6 
Execute an 
lvdisplay
 command to determine if the command was successfully executed. If the 
command did not successfully execute, re-issue the command. 
You should perform any other 
lvextend
 commands that had not been executed before the system failure.
