HP File System Extender (FSE) manual Recall, recall job, Recovery job, Also release, Database Rmdb

recall, recall job	A process, executed by the Partition Manager, that copies the file contents from the FSE media
	to the HSM file system. Once the process is completed, the offline file becomes online again. Its
	file entry is then added to the release candidate list.
recovery	A process, executed by the Partition Manager, that recovers the HSM file system or the File
(FSE recovery)	System Catalog (FSC) without requiring FSE backup copies. The HSM file system is recreated
	from the Name Space Catalog (NSC), while the FSC is recreated either from Fast Recovery
	Information (FRI) or from migrated metadata. FSE recovery can be used as a fallback if restore
	of FSE is not possible due to missing FSE backup data. A recovery job is triggered explicitly on
	an FSE user's request with the fserecover command.
recovery job	See ”recovery (FSE recovery)”.
recycled medium	An FSE medium volume from which all selected data was copied to another medium volume
volume	during media reorganization. The data on recycled medium volumes can no longer be
	retrieved, but the storage space on such volumes can be reused for new migrated data.

redundant data copy A process in FSE that recreates a copy of a file set that has become unreadable, most probably

recreation because the FSE medium to which it was migrated is damaged. The process recreates the damaged data copy using copies of the same data that were migrated to other FSE media pools. Therefore, the main prerequisite to execute this process is a multiple media pool configuration of the corresponding FSE partition. A redundant data copy recreation process is triggered manually by the FSE administrator.

regular release	Release of files on an HSM file system that are on the release candidate list and meet the
	predefined criteria, triggered when the high watermark of usage is reached on the HSM file
	system. The process is stopped when the low watermark on the HSM file system is reached. See
	also ”release”.
release	A process that usually follows a migration or recall, executed by the Hierarchical Storage
	Manager. This process removes the file data from the HSM file system, leaving only the file
	header. Release is triggered by the Partition Manager according to the defined watermarks.
	After release, files are offline and their file entries are removed from the release candidate list.
release candidate	An online file that is scheduled for release and that has either been migrated or was brought
	online by recall.

release candidate list A list of online files that have already been migrated or that have recently been recalled and are waiting to be released. The list is maintained by the Hierarchical Storage Manager.

release policy	A set of rules by which the release process for files on a release candidate list is initiated.
	Configuration parameters for the release policy are specified in the FSE partition configuration
	file. Each FSE partition has its own release policy.
resource	Either an FSE partition, FSE library, FSE drive, FSE media pool, or FSE medium including
(FSE resource)	medium volumes. Each FSE resource is configured using an FSE configuration file and has an
	entry in the Resource Management Database.
Resource	A database with records of all configured FSE resources. It contains all relevant resource
Management	information, such as configuration parameters, resource characteristics, current status, usage
Database (RMDB)	statistics, and relations to other resources. The Resource Management Database is located in
	the directory /var/opt/fse/rmdb (on Linux platform) or in the directory
	%InstallPath%\var\rmdb directory (on Windows platform).
Resource Manager	An FSE daemon (service) responsible for managing data in the Resource Management
(RM)	Database, allocating and releasing FSE resources and providing resource information to other
	FSE daemons (services) and processes. The Resource Manager process name is fse-rm.
