HSM file system A file system, controlled by the FSE software. It is used to store file metadata (name, attributes,
(HSM FS)permissions) and online files of an FSE partition. HSM file systems represent the primary storage space of an FSE implementation. On the Linux platform, HSM file systems are based on the Linux native Ext3 file system and FSE specific attributes are stored as Ext3 extended attributes. On the Windows platform, HSM file systems are based on the Windows native NTFS file system.
HSM file system filter The function of this module is to intercept relevant file system events for the FSE implementation and to report them to the Hierarchical Storage Manager. On Linux platform, the filter is a kernel module providing the HSM file system that is built on top of the Linux native Ext3 file system and HP OnlineJFS/JFS 3.5, respectively. On Windows platform, the filter is a kernel driver and intercepts all accesses to the Windows native NTFS file system.
HSM Health Monitor A utility for monitoring storage capacity on file systems with FSE databases and system files, on
(HHM)HSM file systems, and on the secondary storage space assigned to HSM file systems. The utility can be configured to trigger actions if storage capacity rises above or drops below configurable thresholds.
implementation HP StorageWorks File System Extender. Hardware with installed FSE software. FSE hardware (FSE implementation) includes a tape library with drives, slots, media, and a changer, which is connected to the FSE
server host machine via an SCSI interface. See also ”software (FSE software)”.
initialization | A process that labels the medium volume header on each volume found on a medium and |
| adds the corresponding FSE medium volume entry to the Resource Management Database. If |
| an FSE medium or FSE medium volume contains valid FSE user data and you want to initialize |
| it, you must use forced initialization. |
job | A process, executed by Partition Manager or Management Interface, which executes migration, |
(FSE job) | recall, reorganization, administrative, backup, recovery, and maintenance tasks. Migration and |
| recall jobs are triggered automatically by their respective policy, whereas reorganization, |
| administrative, backup, recovery, and maintenance jobs are triggered with FSE commands. |
library | A SCSI tape library attached to and configured for use in the FSE implementation. |

Library Agent (LA) An FSE agent that handles requests for moving the FSE media between tape drives and library slots and triggers media barcode rescans. The Library Agent process name is
Limited Access Mode One of the two HSM file system filter operational modes. When the HSM file system filter is
(LAM)operating in Limited Access Mode for a particular HSM file system, you are only allowed to browse the directory tree on the HSM file system or read the online data from it. You cannot create, rename, move or delete directories and files, nor change their data or metadata.
Offline data is not recalled from FSE media; instead, the application that is accessing the file receives an error. Limited Access Mode does not need FSE processes to be running on the FSE client. However, if the processes are running, three data movement processes (migration, release, deletion) can be executed – by being either triggered explicitly or started according to the configured FSE partition policies. See also ”Full Access Mode (FAM)”.
Log Analyzer (LA) | A utility for monitoring FSE event log files, which can be configured to periodically analyze |
| these files for specific patterns and send notification |
low watermark | A |
| reached, a regular release process is stopped. |
LTO Ultrium | A Linear |
| supports LTO Ultrium 1, 2, 3, and LTO Ultrium 3 WORM series of tape media, and LTO Ultrium |
| 1, 2, 3, and LTO Ultrium 3 WORM series of tape drives. See also ”medium (FSE medium)”. |
maintenance job | One of the FSE job types that performs maintenance tasks in FSE, namely, the File System |
| Catalog (FSC) consistency check and recreation of redundant migrated data copies. |
