BSY372E All source volumes could not be matched to an appropriate
target volume.
Explanation
One or more of the source volumes could not be matched
to a target volume. The backup is stopped.
User response
Ensure that there are enough targets specified for
the desired number of backup generations. The target units/volumes
must match the size of the source volumes. Also, make sure the specified
target units are not in use for a System Level Backup of another subsystem.
This will make them ineligible for pairing with volumes in this profile.
