Understanding
Partition Media Policy
Settings
A partition’s
Media Type Checking, Media Checking Policy, and
Return Media Identifier
settings help determine how the library
handles differing media types within the same library. You can configure
media policy settings when you manually create or modify a partition.
The key concepts regarding partition media policies are the media
domain, media type, media ID checking, and media identifier.
Media Domain
Gen 2 libraries only support the LTO media domain.
Media Type
The media type is a particular generation of tape technology. Several
media types can exist within one media domain. For example, within the
LTO media domain is the LTO-1 media type, the LTO-2 media type, and
so forth. A media type has an identifier, chosen by the tape
manufacturer or consortium, that enables users and libraries to
distinguish between them. The LTO consortium uses L1, L2, L3, L4, L5,
L6 and L7 to identify the LTO-1, LTO-2, LTO-3, LTO-4, LTO-5, LTO-6 and
LTO-7 media types in a volume serial number.
A single partition can contain a mixture of media types and interface
types within the same domain (for example, LTO-1 and LTO-2 with SCSI
or Fibre Channel interfaces).
To create or modify a partition with mixed media types, you must use
Expert
mode (select
Expert
mode on the
Partitions Wizard
dialog box).
You cannot create or modify partitions with mixed media while in
Automatic
mode or
Simple
mode.
Media ID Checking
Media ID checking policy restricts the movement of tape cartridges
based on the media ID on the barcode label. This policy also helps you
monitor the management of tapes and drives by the host applications.
When you create or modify a partition, you can enable or disable the
Media Type Checking
option. If you choose to enable media type
checking, you also can use the
Media Checking Policy
option to select
from two modes of operation:
Required
or
Not Required
. With either
mode, the library checks whether a cartridge has a valid media ID on the
barcode label.
