82 Managing media
This media pool type is the most common one since it is used for regular archiving of the migrated FSE
implementation data. It contains FSE media that can be overwritten, reorganized, reinitialized, and
reformatted.
• WORM media pool
Used for WORM media only. On these media, data can be recorded only once, therefore WORM
media pool type is particularly suitable for storing permanent archives. It is used to migrate files stored
on an WORM HSM file system accordingly. Note that FSE 3.2 does not support any WORM media.
• Backup media pool
Used for backup media only. A backup media pool is used differently to other media pools; since
backup media do not store user data migrated from an HSM file system, but are only meant for storing
backup copies of the FSE implementation, there is only one backup FSE media pool configured in FSE.
A backup media pool must be configured with only one volume, and backup media in such a pool
should not be initialized. For details about FSE backup, see chapter ”Backup, restore, and recovery” on
page 171.
Configuring a media pool
A configured media pool is a prerequisite for the partition configuration. Each FSE partition is located on a
separate HSM file system and must have at least one configured media pool.
Depending on the data characteristics of each partition, media type which you want to use for archiving
such data as well as the archiving purpose (regular archiving, backup, or WORM for permanent data
archiving) you need to create the appropriate media pool type.
NOTE: The maximum number of medium volumes per disk medium is 255. When configuring a disk
media pool, you need to specify the VolumeSize parameter large enough that 255 * VolumeSize is
larger than the complete disk medium. Otherwise a warning is issued and the number of volumes is set to
255, leaving some unused space.
To configure a media pool, select the appropriate template, modify it and then apply it to configure a new
FSE media pool.
1. Locate the wanted configuration template in the newconfig directory, for example
fse-pool-LTO.cfg, and copy it to the selected directory. For configuration template location, see
”Media pool types and their characteristics” on page 81.
The example below shows how you copy the template fse-pool-LTO.cfg to the directory
MyConfiguration.

2. Set the proper values of the FSE media partitioning parameters in the media pool configuration file.
Check that all other parameters match the characteristics of your media.
Windows specific
Note that some Windows host bus adapter (HBA) drivers (particularly Adaptec and QLogic) do not
support large block sizes by default. You can increase the transfer size by adding the MaximumSGList
value to DWORD registry setting. See section ”Media management problems” on page 201 for
details.
Check the following examples for the specifics according to different pool types, and then continue
applying the modified templates.

# cp /opt/fse/newconfig/fse-pool-LTO.cfg MediaPoolCfgFile
