hp StorageWorks File System Extender Release Notes 13
2New features
Enhanced robustness
FSE 3.2 introduces several changes in the operation of FSE server to enhance the robustness of FSE
operations. The changes enable the FSE server to detect anomalies on media and to prevent improper
operation which could lead to data loss. The enhancements include the following:
• The process of recreating Fast Recovery Information (FRI) can now be performed for WORM and full
media:
• Fast Recovery Information (FRI) is saved to the FRI directory, /var/opt/fse/fri, if there is not
enough space on tape media.
• The process of recreating Fast Recovery Information (FRI) for closed volumes on WORM media now
saves FRI to the FRI directory, /var/opt/fse/fri. Note that FSE does not support WORM
media.
• Automatic correction of FSC during an FSC vs. media check (fsecheck --fsc-media
--autocorrect) invalidates the results of previous reorganization scans. To reorganize media, you
have to rerun the reorganization scan.
• During an FSC recovery, you cannot start the reorganization scan or reorganization job.
• Data formats are now more strictly checked during FSC recovery and FSC vs. media checks
• Improvements of the reorganization job and its interoperability with other jobs.
Support for LTO Ultrium 3 media
FSE 3.2 introduces the same level of support for LTO Ultrium 3 media as for LTO Ultrium 1 and 2 media.
Miscellaneous enhancements
Enhanced fse command
To ease troubleshooting of potential problems with disk volume access on Windows systems, the fse
command was extended with new options --list-volumes [--detail]. These options can be used
to report states of all local volumes, to determine the access mode for a particular volume using the HSM
file system, and to suggest possible solutions in case of problems.
For details, see description of the fse command in the FSE command-line reference.
Enhanced fsepartition command
The fsepartition command was improved for the FSE release 3.2. When retrieving detailed
information using this command (fsepartition --list --detail), two additional entries are
reported:
• FSE partition type: regular, WORM
• current activity on the FSE partition: the partition is enabled, the partition is disabled, a recovery job
runs on the partition, a reorganizational scan job runs on the partition.
For details, see the FSE User’s Guide and the FSE command-line reference.
