standard partition to the AMP. This allows you to control access to
partition storage elements without requiring partition
reconfiguration for host applications.
• Move Media to/from the AMP on page 281 — Physically moves
media from the AMP to a standard partition, or from a standard
partition to the AMP. The media then belongs to the partition into
which it was moved.
Assign Storage
Magazines to/from the
AMP
If a standard partition has used all of its physical slots and needs more
storage elements, you can assign more slots from the storage pool in
the AMP to the partition’s logical element extension address range. The
host will then recognize these slots as accessible and begin using them.
Similarly, if a partition no longer needs all of its storage slots, you can
assign storage elements (magazines) back to the AMP so that these
magazines can be assigned and used by other standard partitions.
The following rules apply when assigning storage elements:
• The AMP must have slots (at least one magazine) available.
• The number of slots you want to reassign are referenced in
magazine increments.
• The standard partition must have sufficient “magazine extensions”
configured to allow magazine assignments.
• Magazines can be reassigned whether or not they contain tape
cartridges. Any cartridges in the magazines will be reassigned to the
new partition along with the magazines, so be careful when
reassigning magazines.
• Operations to reassign magazines will not take standard partitions
offline since the slots were already configured and known to the
host.
To reassign storage:
1 Make sure you are viewing the physical library (from the View
menu, select the name of the physical library).
2 Make sure that the standard partition has sufficient “magazine
extensions” configured (see Create Magazine Extensions in Standard
Partitions on page 276.
