Appendix H Partitioning 205
Partitioning
Remember:
•
Partitioned LSMs cannot communicate with other LSMs within the library
unless they are in the same partition.
•
Elevators and CAPs are
shared resources
—each partition can fully use
these resources for enter and eject operations.
•
No elevator pass-thru operations will occur between LSMs unless they are
defined in the same partition, except when using the CAP to service Rail 1,
regardless of its configured partition.
•
Elevator operation is under the control of the library controller when CAP
operations are issued. The library controller uses the elevators and
HandBots to access the entire capacity of the CAPs for enters and ejects
without regard for the partitions.
•
Partitions can share the ownership of the CAPs. That is, if one host/
partition has CAP A reserved, a different host/partition can have CAP B
reserved, or one host/partition can have both CAPs reserved.
•
Automatic mode is not supported in a partitioned library.
•
Duplicate VOLSERs
3
are supported by the library; however, ACSLS and
ELS/HSC do not, unless:
-
The duplicate VOLSERs are in different partitions.
-
With ELS/HSC managed partitions, the duplicate VOLSERs are in
different control data sets.
-
With ACSLS managed partitions, the duplicate VOLSERs are on
different ACSLS servers.
•
All drives, storage slots and cartridges within a partition are solely owned
by that host or host group.
•
Library complex considerations:
When breaking apart an established library complex to partition libraries
within it, you need to understand the numbering and addressing scheme of
the library.
•
Rails do not need to be included in a partition, they can remain unassigned
to allow for future growth.
3.
VOLSER = volume serial number—the cartridge tape label.
