Resolving Orphaned Cartridges Caused by Partitioning Changes
Partitioning the Library 7-5
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 "CAP States" on
page 10-5.
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" on page 10-4).
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
"Assigning Ownership of a Shared CAP to an FC-SCSI Partition" on
page 10-5).
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 "Viewing Partitioning Reports" on
page 15-2)
■
Audit the library (see "Auditing the Library" on page 13-1)
■
Perform a recovery move on a cartridge (see "Moving Cartridges (Recovery
Moves)" on page 11-1)
For non-partitioned libraries, see "Resolving Orphaned Cartridges Caused by Capacity
Changes" on page 6-3.
