Chapter 4 Configuring Your Library
Working With Partitions
Scalar i6000 User’s Guide 114
Configuration controls, such as FC Host, SCSI Host, and SNW (Storage
Networking) Host provide the means to permit host access to a particular
partition. Multiple hosts can share a single partition, or a partition can be
restricted to one exclusive host.
Host applications control access to elements within the shared partition.
When hosts are
connected directly to drives, this is true exclusively. When
the hosts connect through the MCB or an I/O blade, the library also has
access to partition elements, such as drives and media. Each application
can have a partition assigned to it. Each application uses its partition as if
it were a dedicated physical library.
Understanding Partition
Media Policy Settings 4
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, med
ia type, media ID checking, and media identifier.
Media Domain
4
The media domain is the family of all cartridge types that can be stored in
the same storage slot. Typically, a media domain represents all the
generations and brands of a particular tape technology. Linear Tape Open
(LTO), for example, has many generations and vendors, but all LTO
cartridges are considered to exist in the same media domain.
