Understanding the Media Inventory
The inventory is a record of all the media stored in the library and its
current location (for example, in a specific slot in a TeraPack magazine, in a
drive, or in the TAP). As the library imports media packs (TeraPack
magazines or RXT media packs), the bar code reader on the transporter
reads the bar code labels on the individual cartridges, the magazines, and
RXT media packs (if used). The library uses this bar code information to
update its physical inventory, which is stored in Non-Volatile Random
Access Memory (NVRAM). Using NVRAM ensures that the library retains
the inventory data, even when the library is not powered on.

Storage and Entry/Exit Pools

Entry/Exit pool. An intermediate location for storing media packs
during import and export operations. The media in this pool is either
waiting to be moved into the storage pool by the backup software or

storage pool by the backup software. This media is not available for
writing or reading data.
