Administrator's Guide


Chapter 8. Managing Storage Pools and Volumes

A storage volume is the basic unit of storage, such as allocated space on a disk or a single tape cartridge. A storage pool is a collection of storage volumes that belong to the same device class. The server uses the storage volumes to store backed-up, archived, or space-managed files. The group of storage pools you set up for the TSM server to use is server storage.

The procedures in Chapter 3, Using Magnetic Disk Devices with Tivoli Storage Manager and Chapter 4, Using Removable Media Devices with Tivoli Storage Manager show you how to set up and use devices to provide TSM with server storage. The procedures use the set of defaults that TSM provides for storage pools and volumes. The defaults can work well, but you may have specific requirements not met by the defaults. You may want to set up a hierarchy of storage devices, group data for clients on volumes, and make other adjustments to tune TSM for your systems. See the following sections to learn more. For some quick tips, see Table 17.

In this chapter, most examples illustrate how to perform tasks by using the TSM command line interface. For information about the TSM commands, see Administrator's Reference, or issue the HELP command from the command line of a TSM administrative client.

All of the TSM commands can be performed from the administrative Web interface. For more information about using the administrative interface, see Quick Start.
