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)”.

command

An FSE command-line interface command that communicates with FSE system components

(FSE command)

through the Management Interface. FSE commands are used to configure, monitor, and

 

maintain the FSE implementation.

command-line

A set of FSE commands that are available to FSE users.

Configuration

A directory in the FSE directory layout which contains the currently used and old revisions of the

Database (CfgDB)

FSE configuration files for configured FSE resources.

configuration file

A plain text file used to configure or modify the configuration of an FSE resource. FSE

(FSE configuration

configuration files are stored in the Configuration Database. The Configuration Database is

located in the directory /var/opt/fse/cfg (on Linux platform) or in the directory

 

%InstallPath%\var\cfg (on Windows platform). See also ”configuration file template

 

(FSE configuration file template)”.

configuration file

A pre-designed document for an FSE configuration file, included in the FSE package. It contains

template

default configuration values for configuring an FSE resource. These values should be modified

(FSE configuration file before the FSE administrator can apply the template. FSE configuration file templates are

located in the directory /opt/fse/newconfig (on Linux platform) or in the directory

 

%InstallPath%\newconfig (on Windows platform). See also ”configuration file (FSE

 

configuration file)”.

configuration revisionRevision of an FSE configuration file. Each configured FSE resource has its own set of

(FSE configuration

configuration revisions stored in the Configuration Database. This set represents the

revision)

configuration history of that resource.

consistency check of

A process executed for a particular FSE partition that checks the consistency of the

FSC

corresponding File System Catalog (FSC). It compares the contents of the FSC either with the

 

corresponding HSM file system or with Fast Recovery Information (FRI) for that FSE partition.

 

Any inconsistencies found are reported to the shell output and to the FSE check log. The FSC

 

consistency check is performed by an appropriate type of maintenance job.

CORBA

CORBA is the acronym for Common Object Request Broker Architecture. This is an architecture

 

and infrastructure that computer applications use to work together over networks.

critical watermark

A user-defined value for the critical level of disk space usage on an HSM file system. When this

 

value is reached, a forced release process is started for all files on the Hierarchical Storage

 

Manager’s release candidate list.

daemon (service)

An FSE process that runs on the FSE implementation to provide basic functionality. FSE

(FSE daemon

daemons (services) are: File System Event Manager, Hierarchical Storage Manager, Partition

(service))

Manager, Management Interface, Resource Manager and Service.

Data Location

A part of a File System Catalog. Data Location Catalog contains information about locations of

Catalog (DLC)

the migrated file data on the FSE media. It maintains a full history of file locations. See also

 

”File System Catalog (FSC)”.

database

A file or set of related files with important information on the current status of the FSE

(FSE database)

implementation, characteristics of the FSE implementation, or configuration of the FSE

 

implementation. FSE databases are the Resource Management Database, File System Catalogs,

 

Hierarchical Storage Management Databases, and Configuration Database.
