Chapter 4: Configuring the Library

Working With Partitions

50 Quantum Scalar i40 and Scalar i80 User’s Guide

There are two ways to create partitions:

• Automatically — Library resources are assigned proportionately

among the partitions. Tape drives are grouped according to their

interface type (Fibre Channel or SAS) and media generation (LTO-4,

LTO-5, LTO-6). When you automatically create partitions, you add to

the number of existing partitions. You can create partitions

automatically on either the operator panel or the Web client. For

more information, see

Automatically Creating Partitions on page 51.

• Manually — An administrator can create partitions one at a time.

Creating partitions manually gives you more control over resource

allocation. When you manually create partitions, you add to the

number of existing partitions. You can only create partitions

manually on the Web client. For more information, see

Manually

Creating Partitions on page 52.

You can modify a partition if you need to change its settings. For

example, the partition name, emulation type, media barcode format (to

report to host), and number of assigned tape drives and slots can be

modified. For information on modifying partitions, see

Modifying

Partitions on page 55.

When a partition is no longer needed, it can be deleted. For information

on deleting partitions, see

Deleting Partitions on page 55.

Administrators can create, delete, and control access to all library

partitions. Users can be given access to only certain partitions and

denied access to others. For information on changing partition access

for users, see

Changing Access to Partitions on page 57.

Details on partitions include:

• A partition consists of one tape drive and one slot at a minimum.

The tape drive or slot cannot be shared with another partition.

• The default configuration for the library is one partition per unique

tape drive installed in the library, based on interface type (Fibre

Channel or SAS), media generation (LTO-4, LTO-5, LTO-6), and

vendor type (IBM or HP).

• 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 tape drives in the library.
