Split-Volume backup requirements
Split-volume backup can proceed only if all of the following requirements
are met:
* The volume set must have been previously initialized as a mirrored
volume set through the VOLUTIL utility.
* The volume set must be a nonsystem volume set. Currently, only
nonsystem volume sets can be mirrored.
* All members of the volume set and both partners of each pair must
be present at the time of the split. None of the volumes may be
disabled or suspended, or undergoing a repair.
Once the above requirements have been met, you can proceed to back up the
mirrored disk data.
