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 

 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.
