Partitioning Features and Restrictions

Library Partitioning
Note – Starting with SL500 firmware version 1300 and SL Console version FRS_4.00, library partitioning upgrades must be installed through the SL500 licensing utility. Partitioning established on a library prior to version 1300 is retained permanently. See Chapter 4, “Licensing” for details.
Library partitioning allows sections of the SL500 library to be assigned for exclusive use by specified hosts. For example, you can configure one group of storage cells and drives to be used only for Veritas operations, and another group only for Tivoli operations. This allows you to configure an SL500 library for applications running on multiple hosts and operating systems.
Partitioning Features and Restrictions
This section describes important features and restrictions of library partitioning that will help you to configure and use partitioning in your SL500 library.
■You can configure up to eight partitions within an SL500 library.
■A partition can be as small as a single storage cell, CAP cell, or tape drive. Cells and drives within a partition do not need to be adjacent.
■Storage cells and tape drives allocated to a partition can be used only by the hosts assigned to that partition. Hosts assigned to other partitions cannot access the contents of these cells and drives. See “Storage Cells and Drives” on page 150 for details.
■Storage cells and drives not allocated to any partition cannot be accessed by any hosts. For example, you might leave an area of cells unallocated, in preparation for future partitioning.
■CAP cells can be allocated for exclusive use by a partition, or they can be left unallocated for common use by all hosts. See “Partitions and CAPs” on page 151 for details.
