can be read, but not written. Unlike RO condition, tapes in EOM condition can only be changed to
DOWN. EOM volumes cannot enter either RWC or RO condition.
Volumes in DOWN condition cannot be read, written, created on or mounted. This setting effectively
removes the volume from the system while maintaining the records of the storage segments on it and is
useful for dealing with failed disk or tape volumes. Disks in DOWN condition can be changed to RWC,
RW or RO condition. Tapes in DOWN condition can be changed to RWC, RW or RO condition if the y
have not reached EOM. Tapes that have reached EOM can only be changed from DOWN to EOM.
Disk or tape volumes may be reported in EMPTY condition, but the administrator can never change a
disk or tape condition to EMPTY manually. This condition will be reported when a tape in EOM
condition becomes empty, or a disk in RO condition becomes empty.
The Retire flag controls entry into RWC condition. When the Retire flag is set , the Condition cannot be
changed to RWC, but all other changes are permitted subject to the rules outli ned above. By preventing
entry to RWC condition, retired volumes can be read and written, but new storage segments cannot be
added to the volume. Normal attrition will gradually empty the volume.
To retire a disk or tape volume, set the Condition to any setting other than RWC (typicall y RW for disks
and RO for tapes) and then set the Retire flag. These two changes can be done in a si ngle update of the
Core Server Disk Volume or Core Server Tape Volume window. Note that tapes do not need to be in
EOM condition to be retired.
The Retire flag can be cleared if necessary. Once cleared, the Condition can be changed to RWC, subject
to the rules outlined above.
8.5.6. Moving PVR Cartridg es to Another PVR
The intent of the Move Cartridge operation is to notify HPSS that a cartridge has been moved from one
tape library to another.
Note that this operation will not cause a cartridge to move. Instead, the cartridge should be moved from
the old library to the new library manually before informing HPSS. The operation will fail if the cartridge
has not been ejected from its original robot and injected into the new robot. See the operator manual(s)
for the specific robots involved to determine the procedures for manually ejecting and injecting a
cartridge. Either the source or destination PVR (or both) during a move operation may be an operator
mounted set of drives instead of a robot.
Specifically for shelf tapes, when a Move Cartridge is issued to a shelf tape , the target PVR will check

whether or not the cartridge is physically in the target library. If it is not, then it will be treated as

a move of a shelf tape to a shelf tape in the target library (i.e. maintain its checked-out / shelf

status). If it is physically in the target library, then it will be treated as a move of a shelf tape to an

online cartridge in the target library.
