Resolving Orphaned Cartridges Caused By Partitioning Changes - Oracle StorageTek SL3000 User Manual

Each partition can have either dedicated CAPs or shared CAPs, but not both. Only
partitions with the same host interface type (FC-SCSI or HLI) can share a CAP. Only
one partition at a time can use a shared CAP.
For information about CAP states in a partitioned library, see
page 8-5.
Reserving a CAP in HLI Partitions
An HLI host can reserve a CAP if the CAP is empty, closed, locked, and not already
reserved. Each HLI host reserves a CAP for exclusive use as needed, then releases the
CAP when it is no longer required.
If the host does not release the CAP reservation and you cannot terminate the enter or
eject operation in ACSLS or ELS, you can override the host partition reservation (see
"Overriding a Partition CAP Reservation"
Associating a CAP to an FC-SCSI Partition
Most FC-SCSI hosts typically assume sole ownership of a CAP. Therefore, when using
a shared CAP to enter or eject cartridges, you must manually associate a CAP to the
partition (see
page 8-5).

Resolving Orphaned Cartridges Caused by Partitioning Changes

In partitioned libraries, an orphaned cartridge is located in a slot not allocated to the
original host. Orphaned cartridges can occur when you change the size of a partition,
delete a partition, or move a cartridge to a slot or drive that is not allocated to a
partition.
In a partitioned library, orphaned cartridges can cause data loss. A host that finds an
orphaned cartridge in its partition may treat the cartridge as a scratch volume and
overwrite the data.
To resolve orphaned cartridges, you can:
Generate a report of orphaned cartridges (see
■
page 13-2)
Audit the library (see
■
Perform a recovery move on a cartridge (see
■
Moves)"
For non-partitioned libraries, see
