Tivoli Storage Manager Using the Application Program Interface

Filespace Name

The filespace name is one of the most important components. It can be the name of a file system or disk drive, or any other high-level qualifier that groups related data together. Tivoli Storage Manager uses the file space to identify the file system or disk drive on which the data is located. In this way, actions can be performed on all entities within a file space, such as querying all objects within a specified file space. Because the file space is such an important component of the TSM naming convention, TSM has special calls to register, update, query, and delete file spaces.

The server also has administrative commands to query the file spaces on any node in TSM storage, and delete them if necessary. All data stored by the application client must have a filespace name associated with it. Select the name carefully to group similar data together in the system.

To avoid possible interference, an application client should select different filespace names from those that a backup-archive client would use. The application client should publish its filespace names so that end users can identify the objects for Include and Exclude statements, if necessary.

Note:
On Intel platforms, a drive letter is associated with a file space. When you register or update a file space, you must supply the drive letter. Because the Include-Exclude list refers to the drive letter, you must keep track of each letter and its associated file space. In the sample program dapismp, the drive letter is set to 'G' by default.

For more information, see the sample program installed on your system.
