Maximum number of partially full media
|
Does not apply to the None pool, catalog backup pools, or scratch volume pools.
Specifies the number of partially full media to allow in the volume pool for each of the unique combinations of the following in that pool: Robot Drive type Retention level
The default value is zero, which does not limit the number of full media that are allowed in the pool.
|
Prefer span to scratch | Specifies how NetBackup should select additional media when tape media operations span multiple media. When this parameter is set to yes (default) if a job spans to new media, NetBackup selects media from the scratch pool. NetBackup takes this action instead of using partially full media from the backup volume pool. When this parameter is set to no, NetBackup attempts to select partially full media from the backup volume pool to complete the specified operation. The no setting lets NetBackup use partially full media in the backup volume pool instead of always spanning to a scratch tape. Set the maximum number of partially full media option with the vmpool -create or the vmpool -update command. |

Pool name
|
The is the name for the new volume pool. Volume pool names are case-sensitive and can be up to 20 characters.
See About reserved volume pool name prefixes.

|
Scratch pool
|
Specifies that the pool should be a scratch pool.
It is recommended that you use a descriptive name for the pool and use the term scratch pool in the description.
Add sufficient type and quantity of media to the scratch pool to service all scratch media requests that can occur. NetBackup requests scratch media when media in the existing volume pools are allocated for use.
