mounted, the volume serial number read from the media
did not match what was expected. The volume is ejected
to the convenience I/O station.
This is likely caused by human intervention in the library
that involved moving physical cartridges between storage
cells and, when the library was returned to auto mode,
inventory update was disabled. Without performing
inventory update, the library has no way of updating its
database to know where cartridges have been moved.
Message	1. Notify your system administrator.
Orphaned logical volume xxxxxx found.	2. If this intervention occurs multiple times, call your
	service representative.
Probable Cause
During a check of the Virtual Tape Server database, a
reference to logical volume xxxxxx was found, but there
is no record of its physical location. This could be the
result of a hardware or internal software problem. Any
data associated with the logical volume is lost.
