Chapter 10. Managing Storage Pools and Volumes

When you configure devices so that the Tivoli Storage Manager server can use them to store client data, you create storage pools and storage volumes. This section gives you overviews and details on storage pools and storage volumes.

The procedures in Chapter 3, Using Magnetic Disk Devices and Chapter 5, Configuring Storage Devices 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. Three common reasons to change the defaults are the following:

You can also make other adjustments to tune the server for your systems. See the following sections to learn more. For some quick tips, see Table 13.

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