90 Sun StorageTek SAM Archive Configuration and Administration Guide • Version 4, Update 6, 04/07

A VSN pool is a named collection of volumes. VSN pools are useful for defining

volumes that can be available to an archive set. As such, VSN pools provide a useful

buffer for assigning volumes and reserving volumes to archive sets. You can use

VSN pools to define separate groups of volumes by departments within an

organization, by users within a group, by data type, and according to other

convenient groupings.

If a volume is reserved, it is no longer available to the pool in which it originated.

Therefore, the number of volumes within a named pool changes as volumes are

used. You can view the VSN pools by issuing the archiver(1M) command in the

following format:

The syntax of a VSN pool definition is as follows:

The following example uses four VSN pools: users_pool, data_pool,

proj_pool, and scratch_pool. A scratch pool is a set of volumes used when

specific volumes in a VSN association are exhausted or when another VSN pool is

exhausted. If one of the three specific pools is out of volumes, the archiver selects the

scratch pool VSNs.

CODE EXAMPLE 3-33 shows an archiver.cmd file that uses four

VSN pools.
