4 Managing media
The way you manage FSE media can significantly increase the stability and performance of your FSE
implementation. Managing media consists of tasks that are related to the media life cycle, from formatting,
initialization and optional duplication for data vaulting, to replacing worn-out media and media
reorganization.
FSE supports several media types, which are grouped into appropriate media pools. These media pools
are created by the FSE administrator according to their purpose, for example, a backup pool for media is
used only for backup and holds only one type of media.
All media must be formatted and initialized before they can be used for data storage by FSE. Then you are
able to track media pools and media, review their characteristics and statuses, make exact copies of your
media, or decide on multiple copies made at once. For specifics regarding disk media, see ”Disk media”
on page 87.
This chapter includes the following topics:

FSE media pools
An FSE media pool is common storage for the migrated HSM file system data. It groups media of the same
type into a logical unit, which is tracked as a group. All media in the same FSE media pool share such
characteristics as number of medium volumes, availability of system volumes, capacity of medium volumes,
and so on (see ”FSE media” on page 86 for more information on media types and characteristics). Media
in the same media pool can be located in multiple FSE tape libraries or disk systems.
A media pool is related to one FSE partition only and cannot be assigned to more than one partition.
However, an FSE partition can have more than one media pool assigned to it, but the assigned media
pools must be either regular or WORM. Note, however, that FSE 3.2 does not support any WORM media.
The number of media pools assigned to the FSE partition determines the number of copies to be made. For
more information on multiple copying, see ”Multiple copying” on page 131.
The procedures in this section provide instructions for:
• Media pool types and their characteristics, page 81
• Configuring a media pool, page 82
• Determining the configured media pools, page 84
• Checking the status of a particular media pool, page 85
Media pool types and their characteristics
The media pool type is defined in the media pool configuration file. Location of configuration templates is
platform-dependent.
Linux specific
Configuration templates for FSE media pools are located in the directory /opt/fse/newconfig.
Windows specific
Configuration templates for FSE media pools are located in the directory %InstallPath%\newconfig.
The value of %InstallPath% depends on the choice made in the FSE installation process. It defaults to
C:\Program Files\Hewlett-Packard\FSE.
For more information on editing templates, see ”Configuration basics” on page 38. Examples of FSE
media pool configuration are listed in the next section, ”Configuring a media pool” on page 82.
