Configuring and Using Backup Devices

Using Several Drive Types in a Library

On Windows and UNIX systems, you can configure separate media pools for different groups of drives. This allows you to use different density settings for different drive types. For example, you could create a DLT 4000 pool and a DLT 8000 pool.

The related setting in the device definition must be used at the time the media are formatted. For example, the media in the pool for the DLT 8000 highest density must be formatted by a DLT 8000 in highest density setting.

The free pool concept cannot be used across such pools. This would not identify media from the other pool to the devices correctly; they would be seen as “foreign” media. The free pool concept can at most be used only in a single pool (like the DLT 8000 pool), in case the same media type (DLT) is written in an incompatible way.

Care must be taken during restore, since media from a given pool can only be used with related devices.

To configure new media pools, refer to the online Help index keyword “configuring media pools”.

To modify media pool settings for a drive, modify the drive properties. For detailed steps, refer to the online Help index keyword “modifying, media pools”.
