Chapter 4 Configuring Your Library
Working With Partitions
Scalar i2000 User’s Guide 109
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 (for example, LTO), but the
library does not allow the cartridge to be moved from storage to a drive
that does not have a matching 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 matching type (for example, an LTO-2 cartridge will
not be allowed to move to an LTO-1 drive).
Return Media Identifier 4
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 18 explains the media type identifiers and assumptions.
