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
■
Partition 1 is owned by an HSC host.
Example 2: two-partition library
■
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.
