Troubleshooting

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.
