Automatic Media Discovery - Spectra TFinity User Manual

Chapter 9 — Configuring and Using Media Lifecycle Management
Spectra Certified MLM‐enabled LTO media was first available from
Spectra Logic on November 15, 2007. The following table summarizes the
level of information reported through MLM for media purchased before
and after MLM became available.

Automatic Media Discovery

Overview The Media Auto Discovery feature is a background process that
loads MLM‐enabled cartridges into a TS11xx technology drive or an LTO‐4
or later generation drive, records the MLM information to the cartridge
MAM, adds the cartridge to the MLM database, and returns the cartridge
to its original location. The process is performed by the library
independently from the storage management software. Media Auto
Discovery must be enabled on the library, as described in Enabling MLM
and Configuring Global Settings on page 295, before it can be used.
When Media Auto Discovery is enabled, MLM provides two options for
proactively discovering media in a partition:

Note: If you do not want to use automatic media discovery, you can
wait until the library loads and then unloads each cartridge from
an MLM‐capable drive for the first time during normal
operation. When the cartridge is unloaded from the drive, the
library discovers it and records the MLM data to the cartridge
MAM and enters the data into the MLM database.
from the cartridge MAM and adds it to the MLM database. The Media
Auto Discovery process only operates on newly imported cartridges
that are not already in the MLM database.
Media Auto Discovery loads and reads the MAM in the tape, but
Note:
does not thread the tape. The drive only reports the maximum
and remaining capacity for the tape after the tape is threaded.
Therefore, these statistics report as ʺ0ʺ until a drive reads from,
or writes to, the tape.
