86 Managing media
In the fsepool command output, locate the name of the owning partition and supply it as an argument to
the fsepartition command as follows:
The output of this command lists the names of all media pools that are currently assigned to the selected
partition, and their current status, as follows:
• the total and available capacity of all data volumes on media belonging to the media pool,
• the percentage of data volume usage,
• the total and available capacity of all system volumes on media in the media pool,
• the percentage of system volume usage,
• the numbers of good, unreliable, unusable, and uninitialized media of the media pool.
Excerpt from the fsepartition --status output
FSE media
An FSE implementation supports tape media as well as disk media. Each FSE medium has an entry and
properties written in the Resource Management Database (RMDB) and is assigned to one FSE media pool
according to its type. The Resource Manager identifies the medium with a barcode, which is either
acquired automatically from the media library or specified manually when adding media to the media
pool. A medium barcode must be unique - no other tape or disk medium in any of the libraries managed
by a particular FSE implementation can have the same barcode.
Once the medium is added to the FSE media pool, it can be prepared for use by the FSE implementation.
Preparation includes formatting and initializing of the FSE media. Formatting depends on media
technology support for multiple volumes. Next step is initialization, which overwrites the volume header
and adds the medium volume entry to the Resource Management Database. Both media formatting and
initialization are processed by an administrative job and are executed by the Back End Agent.
Disk media emulates tape media to a great extent and can be used for regular archiving of the migrated
FSE implementation. The advantage of using disk media is accelerated recall of offline files.
The fsemedium command is used to monitor and manage FSE media. It is also used to invoke
administrative jobs, which perform FSE media formatting and initialization of new or already used media.

FSE medium volumes
There are two types of medium volumes:
