In Required mode, if the library does not find a valid media ID on a
cartridge, the library does not allow it to be moved into or within the
library. If the library finds a valid media ID, the library allows it to be
moved from an I/E station into a partition that contains magazines
matching the media domain of the cartridge, but the library does not
allow the cartridge to be moved from storage to an incompatible drive
type (for example, an LTO-2 cartridge will not be allowed to move to an
LTO-1 drive).
In Not Required mode, if the library does not find a valid media ID on a
cartridge, the library allows it to be moved into or within the library as
long as the I/E station magazine, storage magazine, or drive matches
the media domain of the cartridge. If the library finds a valid media ID,
the library does not allow the cartridge to be moved from storage to a
drive that does not have a compatible type (for example, an LTO-2
cartridge will not be allowed to move to an LTO-1 drive).
Return Media Identifier
For the media policy settings, the library makes assumptions about a
media identifier and its position in a media barcode label. To be
considered a media identifier, the identifier characters must be correct
for the media domain and media type. Also, the identifier, which for
some media types can consist of more than one character, must be
complete and in the correct location. The correct characters in the
wrong position are not viewed as a media type identifier. In a physical
library or partition containing mixed media, the media identifier is not
required for all cartridges.
Table 24 explains the media type identifiers and assumptions.
