34 Configuring Your Library
Working With Partitions
The Setup Wizard: Partitioning screens allow administrative users to select the number of new library
partitions to create.
Partitions are virtual sections within a library that present the appearance of multiple, separate libraries for
purposes of file management, access by multiple users, or dedication to one or more host applications. The
library must contain at least one unassigned tape drive and slot to create a partition.
At any time after the initial configuration of the library, administrative users can add to the number of existing
partitions by selecting
Setup > Partitions on the web client or Setup > Create Partitions on the operator
panel.
There are two ways to create partitions:
• Automatically — assigns library resources proportionately among the partitions, grouping tape
drives according to their interface type (FC or SCSI). You can create partitions automatically on
either the operator panel or the web client. When you automatically create partitions, you add to the
number of existing partitions.
• Manually — an administrative user creates partitions one at a time. Creating partitions manually
gives you more control over resource allocation. You can create partitions manually only on the web
client. When you manually create partitions, you add to the number of existing partitions.
The maximum number of partitions that can be created is equal to the number of drives in the library. Table
5 shows the possible number of partitions that can be created for each of the available library configurations.
Details on partitions include:
• Administrative users can create, modify, delete, and control access to all partitions. Users can be
given access to only certain partitions and denied access to others.
• Partition names are limited to 12 lower-case alphanumeric characters and underscores ( _ ).
• The maximum number of partitions that can be created is equal to the number of drives in the
library.
• At minimum, a partition consists of one tape drive and one slot. The tape drive or slot cannot be
shared with another partition (an exception to the sharing restrictions are cleaning tapes, which can
be shared among all partitions).
• I/E station slots are shared between all partitions. Partitions take temporary ownership of I/E station
slots when importing or exporting tape cartridges.
• By default, the library has one partition if your library contains one tape drive type (SCSI or FC). If
your library contains both SCSI and FC tape drives, the default is two partitions. The library
automatically groups the FC tape drives in one partition and the SCSI tape drives in another. The
library does not support mixed tape drive types in a single partition.
