Glossary
This glossary defines terms used in this guide or related to this product and is not a comprehensive
glossary of computer terms.
administrative job
(admin job)
A process, executed by the Management Interface, which performs formatting and initialization
of the FSE media.
administrator
(FSE administrator)
A system administrator who installs, configures, monitors, and maintains an FSE
implementation.
agent
(FSE agent)
An FSE process that executes tasks on request by FSE jobs and some FSE commands. The FSE
agents are the Back End Agent and the Library Agent.
Back End Agent
(BEA)
An FSE agent which executes migration, recall, maintenance and recovery jobs; it also formats
and initializes FSE media. All read and write operations on the FSE media are handled by the
Back End Agent. The Back End Agent process name is fse-bea.
backup
(FSE backup)
A process that creates backup image with complete and consistent state of the FSE server at a
particular point in time. The backup image can be used to recover the server in case of
disaster. Backup image file can be located on a local or remote disk, or stored on tape media
of the backup FSE media pool.
backup job A specific FSE job type that executes the backup process. Backup jobs can be started by FSE
administrator with the fsebackup command. See also ”backup (FSE backup)”.
backup log
(FSE backup log)
A file that stores information about activity of the FSE backup process. FSE backup log is named
backup.log and located in the directory /var/opt/fse/log (on Linux platform) or in the
directory %InstallPath%\var\log (on Windows platform).
backup media pool
(backup FSE media
pool)
A special type of FSE media pool, used exclusively for backup and restore of the FSE
implementation. In contrast to regular FSE media pools, the media cartridges in the backup FSE
media pool do not contribute to the secondary storage space available to FSE users. See also
”media pool (FSE media pool)”.
capacity disk A disk with large storage space which stores file systems either dedicated to the FSE disk media
or assigned to the FSE disk buffer. If used for the FSE disk media, it can be either locally
mounted on the consolidated FSE system or FSE server, or used on a remote system which is
accessible via CIFS or NFS protocol. If used for the FSE disk buffer, it can only be locally
mounted on the consolidated FSE system or FSE server. Note that configurations with several
FSE disk buffer file systems residing on the same capacity disk may reduce the performance of
the FSE disk buffer.
check log
(FSE check log)
A file that records all the inconsistencies found by the maintenance job, which performs a File
System Catalog consistency check for a specified FSE partition. FSE check logs are named
check_hsmfs_fsc_PartitionName (in case of the FSC vs. HSM file system consistency
check) or check_media_fsc_PartitionName (in case of the FSC vs. FSE media
consistency check). They are located in the directory /var/opt/fse/log (on Linux platform)
or in the directory %InstallPath%\var\log (on Windows platform).
CIFS The file sharing protocol used on Windows platform. This is one of the protocols used for
accessing files on an HSM file system from a remote machine, particularly a Windows client. A
smb server (Samba) must be running on the machine hosting the HSM file system, in order to
allow file transfers. See also ”Samba”.
