Discovery Process The discovery process can either be manually initiated
by you or set to run automatically so that the library discovers the
cartridges and adds their information to the MLM database shortly after a
cartridge is imported into the library. The discovery process is independent
of any storage management software.
The discovery process depends on whether the library is using Media Auto
Discovery or PreScan. With Media Auto Discovery the library reads the
barcode label on each new cartridge in the partition; with PreScan the
library reads the barcode label on every cartridge in the partition. If a
barcode is not already in the MLM database, the library loads the cartridge
into a drive and performs either a PreScan or the basic Media Auto
Discovery.
 If the cartridge is MLM‐enabled, the library collects the available MLM
 If the cartridge is not MLM‐enabled, the library collects the cartridge
When the discovery process is complete, the drive unloads the cartridge
and the library returns the cartridge to its original location. Each
subsequent load/unload updates the MLM database and the cartridge
MAM, providing ongoing tracking and reporting for the cartridge.

also written to the MAM in the cartridge.
barcode label information, the cartridge health information, and the
name of the partition where the cartridge currently resides. It then adds
this information to the MLM database.
Note: After you enable Media Auto Discovery, importing a cartridge
into a partition triggers the discovery process in that partition.
