HP StoreEver ESL G3 Tape Libraries - Manual (Page 48)

NOTE:
If the partition is not offline, you will receive a message stating that the partition must be taken
offline prior to performing the operation. Ensure backup applications are not currently using the
partition. Click Yes to continue.
Automated Media Pool (AMP)
NOTE:
Magazines can not be assigned if there are no automated media pool partitions configured.
Automated Media Pool (AMP), also referred to as a Library Managed partition in the LMC, enables
the creation of a virtual partition that can be dynamically allocated to other, previously-created
partitions, all without disrupting host or application operation. AMP magazines are presented to host
applications as part of a standard partition, but AMP magazines appear as “inaccessible” until they
are assigned to a normal partition.
AMP may be thought of as “thin provisioning” for a tape library. Both a partition license and an AMP
license are required to enable AMP on a library.
An AMP example is shown in the following figure:
In this example, three standard partitions have been created to present to SAN hosts. Partition 4 is a
Library Managed (AMP) partition from which slots can be reassigned. As shown in the example, each
partition contains 100 physical storage slots. The host application will see each partition as containing
a total of 130 storage slots, 30 of which will be tagged as “inaccessible”.
To create an AMP partition:
1. Log on as an administrator.
2. Make sure that you are viewing the physical library. From the View menu or in the Managed
Views region of the LMC, click the name of the physical library.
3. Click Setup > Partitions > Configure.
The Partitions dialog box displays a list of partitions currently configured within the library.
4. Click Create.
The Partitions - Choose Creation Mode dialog box appears.
5. Select Expert, and then click Next.
The Partitions - Choose Partition Properties dialog box appears.
