1.On all systems that host either an internal (part of the consolidated FSE system) or an external FSE client, close all applications that access files or directories on HSM file systems and make sure that all non-FSE processes which have had locks to objects on these file systems are terminated.

You can use the fuser or lsof command to find out which files are being accessed on the HSM file system. For details, refer to the fuser and lsof man pages.

2.Optionally, check the consistency of the File System Catalogs (FSCs) by comparing them with the corresponding HSM file systems.

Proceed as follows:

a.Before starting the consistency check, make sure that all consistency checking processes that might have already been running on FSE partitions have completed. Inspect the following log files:

/var/opt/fse/log/check_hsmfs_fsc_PartitionName.log

You can proceed with the next steps only if the log files show no current consistency checking activity.

b.On all systems that host FSE partitions, remove old consistency check log files. Run the following commands:

#cd /var/opt/fse/log/

#rm -f check_hsmfs_fsc_*

c.Start the consistency check for all configured FSE partitions. For each FSE partition, invoke the following command:

#fsecheck --fsc-hsmfs PartitionName

Search the resulting log files for inconsistency indicators. Before proceeding with shutting down the FSE implementation, you are urged to eliminate all inconsistencies found. For details, see the FSE user guide, chapter ”Monitoring and maintaining FSE”, section ”Checking the consistency of the File System Catalog”.

3.If you are upgrading your FSE product with an FSE system maintenance release or an FSE hot fix, on each external FSE client on which FSE utility daemons are running, you need to stop the FSE utility daemons:

a.To stop the HSM Health Monitor daemon on the local system, run the following command:

#hhm stop

b.To stop the Log Analyzer daemons on the local system, run the following commands:

#/etc/init.d/loganalyzer stop

#/etc/init.d/loganalyzer_messages stop

4.On each external FSE client, shut down the currently running FSE processes using the fse --stopcommand. The shut-down progress is shown in the command output:

# fse --stop

File System Extender (FSE) specifications

HP File System Extender (FSE) is a sophisticated solution designed to optimize data storage management for enterprises that deal with large volumes of unstructured data. This technology addresses the challenges of data growth and the need for effective data retention strategies, enabling organizations to store and manage their information more efficiently.

One of the main features of HP FSE is its ability to intelligently migrate data between primary and secondary storage. By utilizing policies that determine when to move infrequently accessed files to lower-cost storage environments, FSE helps reduce the strain on primary storage systems and saves on costs associated with high-performance storage solutions. This tiered approach to data management ensures that organizations can access the data they need quickly while still maintaining an efficient overall storage architecture.

Another notable characteristic of HP FSE is its seamless integration with existing storage infrastructures. The solution works with a variety of storage systems, allowing organizations to utilize their current investments without the need for significant changes to their infrastructure. This interoperability is powered by advanced technologies that facilitate data migration and retrieval, ensuring a smooth transition for organizations looking to optimize their storage strategies.

Additionally, HP FSE is equipped with robust reporting and analytics capabilities. This functionality provides organizations with insights into their storage usage, helping them understand data patterns and optimize their storage environments accordingly. By having visibility into which files are accessed most frequently and which are rarely used, organizations can make informed decisions on data retention policies and storage management.

Security is paramount in data management, and HP FSE addresses this concern by implementing advanced data protection features. This includes data encryption, secure access controls, and compliance with industry regulations, ensuring that sensitive information is safeguarded throughout its lifecycle.

Overall, HP File System Extender is a comprehensive data storage solution that combines intelligent data management, seamless integration, insightful analytics, and robust security features. By leveraging these capabilities, organizations can efficiently manage their unstructured data, lower costs, and enhance operational efficiency, making it an invaluable tool in today’s data-driven landscape.
