sbom_backup -x split.vg.backup sbvg
2. To split the mirrors of the volume group sbvg, along with the mirrors for the
logical volumes lv27 and testlv in datavg, forcing the process to continue if
errors are encountered, and displaying the output to the screen, use the
command:
sbom_backup -F -v sbvg lv27 testlv
Note: If you do not specify a Backup Command File with the -x flag, you will

exit at the command prompt to allow the Offline Mirror process to begin
re synchronizing the split mirrors.

the process was terminated inadvertently. issue this command to clean up and
re synchronize mirrors:
sbom_backup -R
Manual Recovery
If you need to recover from a failed Offline Mirror backup attempt, but the
automated recovery process was unsuccessful, you will need to manually recover
from the failed backup attempt.
To recover manually, you would do the following:
1. Obtain a listing of all of the active volume groups on your system using the
lsvg -o command.
2. Obtain a listing of all of the logical volumes in each volume group using the
lsvg -l vgname command.
