HP File System Extender (FSE) manual Mode LAM

File System Event	A daemon (service) on the FSE client which receives notification about mount events for the
Manager	HSM file system and triggers the startup of the appropriate Hierarchical Storage Manager. The
	File System Event Manager process name is fse-fsevtmgr.
forced release	Release of all files on an HSM file system, which are on the release candidate list, regardless of
	their retention time and file size. Forced release is triggered when the critical watermark of
	usage is reached on the HSM file system. The process is stopped in the moment when the high
	watermark on the HSM file system is reached. See also ”release”.
formatting	A process that partitions a medium into medium volumes, according to the parameters
	specified in the FSE media pool configuration. During formatting all data on the medium is
	erased. If an FSE medium contains valid FSE user data and you want to format it, you must use
	forced formatting.
Full Access Mode	One of the two HSM file system filter operational modes. When HSM file system filter is
(FAM)	operating in Full Access Mode for a particular HSM file system, you are allowed to make
	changes to the data located on the HSM file system, and use all the HSM file system
	functionality that the FSE system provides. For example, you can create, rename, move or delete
	directories and files, and change their data or metadata. In this mode, all data movement
	processes (migration, release, recall, deletion) can be executed – by being either triggered
	explicitly or started according to the configured FSE partition policies. See also ”Limited Access
	Mode (LAM)”.
good medium	A usable FSE medium in its fully operational state. In this state, the medium may have any of the
	following statuses: uninitialized, free, empty, in use, full. This state lasts as long as
	the medium is in a good condition, that is, no write and read errors are detected while writing
	data to and reading data from the medium.
Hierarchical Storage	A database with migration candidate and release candidate lists for files on the HSM file
Management	system. Each FSE partition has its own Hierarchical Storage Management Database.
Database (HSMDB)
Hierarchical Storage	A file which contains transaction information for Hierarchical Storage Management Databases.
Management	It is designed to increase the database robustness. HSMDB journals contain information about
Database journal	already applied and pending database transactions. Hierarchical Storage Management
	Database journals are located in the directory
	/var/opt/fse/part/PartitionName/hsm/journal (on Linux platform) or in the
	directory %InstallPath%\var\part\PartitionName\hsm\journal (on Windows
	platform).
Hierarchical Storage	A part of the FSE client that handles file system events relevant for the FSE implementation and
Manager (HSM)	enforces migration, release, and recall policies. The Hierarchical Storage Manager process
	name is fse-hsm.
Hierarchical Storage	A list of files, maintained by the Hierarchical Storage Manager, which are candidates for
Manager list (HSM	migration or release. HSM lists are: a dirty file list (the list of changed files), a migration
list)	candidate list, and a release candidate list.
high watermark	A user-defined value for the high level of disk space usage on an HSM file system. When this
	value is reached, a regular release process is started for all files that are on the Hierarchical
	Storage Manager's release candidate list and that have passed their migration or recall
	retention period, and are larger than the defined MinFileSize.
host	A computer system that hosts either a consolidated FSE system, an FSE server, or an FSE client.
(FSE host)
hot fix	A package with updated FSE binaries, FSE configuration files, or other FSE system files that are
(FSE hot fix)	applied to the FSE implementation at a specific site, in order to solve one or more problems
	reported by an FSE customer.
