If the host fails, repeat the step to ensure all configuration data is written to the new disk.
Note If this replacement procedure is being performed now on another host system and there is no need to
execute any lvreduce commands, then the configuration file can be updated with thevgcfbackup command.
Step 5
Enter the following command to attach the replaced disk to the active volume group:
# vgchange -a y <volume group name>
For example: # vgchange -a y /dev/vg00
Step 6
Enter the lvextend command to transfer the mirrors onto the replaced disk. It will take time to copy all of the
original data to the mirrored extents. The logical volumes are accessible to users' applications for two-way
mirroring during this command.
# lvextend -m <mirror_copies> <LV name> physical volume path
For example, for two-way mirroring:
# lvextend -m 1 /dev/vg00/lvol4 /dev/dsk/c2t4d0
For three-way mirroring:
# lvextend -m 2 /dev/vg00/lvol5 /dev/dsk/c2t4d0
If the host fails during this step, execute an lvdisplay command to determine if the lvextend command was
successful. If the command did not successfully execute, reissue the command. Perform any other lvextend
commands that were not executed before the system failed.
At this point, the system should be fully functioning.
Procedure Completed!
Congratulations!
