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)
Archived copies of FSE databases and system files, stored on FSE media, used for restore of the
FSE implementation. Backup copies represent a complete state of the FSE system components at
a particular moment. The creation of the FSE backup is triggered by the fsebackup
command.
backup job A process which makes a backup copy of the HSM file systems, FSE databases and system files
onto FSE media in the FSE backup media pool. The backup job is started by the FSE
administrator with the fsebackup command.
backup log
(FSE backup log)
A file that records relevant information on events that took place during the FSE backup. The
FSE backup log, named backup.log, is located in the directory /var/opt/fse/log (on
Linux platform) or in the directory %InstallPath%\var\log (on Windows platform).
backup media pool
(FSE backup 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 FSE backup
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 high-capacity storage that stores FSE disk media file systems. Capacity disks can be
located on the consolidated FSE implementation or the FSE server, or on a remote system where
they are accessed via CIFS or NFS protocol. Optionally, capacity disks can store large FSE disk
buffer files.
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”.
client (FSE client) A set of FSE daemons/services responsible for managing the HSM file systems on the FSE
partitions. These daemons/services are: File System Event Manager, Hierarchical Storage
Manager, and Service, with additional FSE Windows Service on Windows systems. See also
”external client (FSE external client)”.
