Regardless of the monitoring setting, the fsemedium command logs the recreation process progress into the FSE event log, while any errors encountered during the recreation process are logged into the FSE error log.

Linux specific

On Linux platform, FSE error log is located in the directory /var/opt/fse/log.

Windows specific

On Windows platform, FSE error log is located in the directory %InstallPath%\var\log.

The value of %InstallPath% depends on the choice made in the FSE installation process. It defaults to C:\Program Files\Hewlett-Packard\FSE.

Resolving situations with no alternative migrated copies

In terms of data safety, a configuration with only one FSE media pool assigned to a particular FSE partition is dangerous. If a damaged, unusable FSE medium is part of such an FSE media pool, the only migrated data copy is permanently lost. The only exceptions are the migrated file generations on the unusable medium that are still present on the HSM file system. These file generations would normally be lost during their release, but you can prevent their loss by manually adding them to the dirty file list.

To put online files on the dirty file list, enter the following command at the command prompt:

fsefile -M Filename...

Note that fsefile must be run on the FSE client that hosts the FSE partition.

The command puts all specified files on the dirty file list. This way, the files are scheduled for regular migration according to the migration policy defined for the FSE partition. To migrate the files immediately after the MinFileAge interval for these files has expired, use the fsefile --trigger-migrationcommand.

For details on the MinFileAge parameter, see ”Migration policy parameters” on page 127.

For more information on the fsefile command, see the FSE CLI reference.

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.
