Sun Microsystems SL8500 manual Planning Library Partition Configurations

Configuring Library Partitions

Planning Library Partition Configurations

Library partitioning requires careful planning, a thorough knowledge of library wall and slot mapping, and expertise in configuring and administering ACSLS and HSC host software applications. There must be clear communication among all parties involved, including system programmers and administrators, library operators, and your Sun service representative.

See “Library Partitioning” on page 22 for details about library partitioning features and requirements.

Before creating partitions, you must verify that all tape drives and cartridges have been moved to the proper location, according to the planned host/rail assignments. For example, if rails 1 and 2 will be owned by an ACSLS host, only ACSLS-compatible drives can be installed at those rail positions, and all cartridges containing data for the ACSLS host must be migrated to those rails.

See the SL8500 Modular Library System Best Practices Guide for complete information about partition planning.

Following are examples of valid library partition configurations.

Example 1: one-partition library

Rail Library A

1

2

Partition 1, Host A (HSC)

3

4

■Partition 1 is owned by an HSC host.

Example 2: two-partition library

Rail Library B

1

Partition 1, Host A (HSC)

2

3Partition 2, Host B (ACSLS)

■Partition 1 is controlled by an HSC host.

■Partition 2 is controlled by an ACSLS host.

■Rail 4 is unassigned and therefore not available for use.
