Table 22. Intervention Required Conditions relating to a Virtual Tape Server in the Library (continued)
Intervention Required Condition Resolution Actions
Message
A stacked volume has a label mismatch and has been
ejected to the convenience I/O station. Internal:
xxxxxx, External: yyyyyy
Probable Cause
During validation that the correct stacked volume was
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.
1. Remove the cartridge from the convenience I/O
station.
2. If human intervention in the library is the cause,
perform an inventory update operation.
3. If human intervention is not the cause, check the
external label of the cartridge for damage and relabel
if necessary.
4. Place the cartridge in the convenience I/O station.
Message
Orphaned logical volume xxxxxx found.
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.
1. Notify your system administrator.
2. If this intervention occurs multiple times, call your
service representative.
Message
The Tape Volume Cache is degraded (Error Code
xxxx). (VTS z)
Probable Cause
A disk drive in one of the Tape Volume Cache storage
capacity features of Virtual Tape Server z has failed.
Operations with the Virtual Tape Server continue, but
performance degradation may be experienced. Service is
required.
1. Record the error code and contact your service
representative.
Message
A permanent, non-recoverable Tape Volume Cache
error has occurred. (VTS z)
Probable Cause
During the initialization of the Virtual Tape Server z,
unrecoverable errors were detected with the Tape Volume
Cache. The Virtual Tape Server is unusable. Service is
required.
1. Contact your service representative.
