IBM Tivoli Storage Manager, Version 7.1

DEFINE STGPOOL (Define a storage pool)

Use this command to define a primary storage pool, copy storage pool, or an active-data pool.

A primary storage pool provides a destination for backup files, archive files, or files that are migrated from client nodes. A copy storage pool provides a destination for copies of files that are in primary storage pools. An active-data pool provides a destination for active versions of backup data that are in primary storage pools. The maximum number of storage pools that you can define for a server is 999.

All volumes in a storage pool belong to the same device class. Random access storage pools use the DISK device type. After you define a random access storage pool, you must define volumes for the pool to create storage space.

Tip: Raw partitions generally provide the best performance, however an IBM® Tivoli® Storage Manager server running Solaris 10 does not support ZFS raw partitions.

Sequential access storage pools use device classes that you define for tape devices, files on disk (FILE device type), and storage on another server (SERVER device type). To create storage space in a sequential access storage pool, you must allow scratch volumes for the pool when you define or update it, or define volumes for the pool after you define the pool. You can also do both.

Restriction: If a client is using the simultaneous-write function and data deduplication, the data deduplication feature is disabled during backups to a storage pool.

The DEFINE STGPOOL command takes four forms. The syntax and parameters for each form are defined separately.
