In the example, the first medium volume on the FSE medium with barcode 052002 was recycled during the reorganization job and can be reused.

Before recycled medium volumes can be reused, they must be reinitialized. The reinitialization is performed automatically at the end of the FSE reorganization job. All recycled medium volumes are reinitialized in sequence. If the reorganization job has been terminated for some reason before medium volume reinitialization, you have to reinitialize the recycled volumes manually. For more information on initializing FSE medium volumes, see section ”Initializing media” on page 103 and the FSE CLI reference.

Recreating redundant copies of migrated data

FSE enables you to assign several FSE media pools to the same FSE partition, in order to store multiple copies of the migrated data on FSE media (via the Pools variable in the FSE partition configuration file). In such a configuration, each media pool contains one copy of the migrated data from the HSM file system.

Having multiple copies of the migrated data is useful for various reasons, including the possibility of storing a particular copy in a vault and increasing the overall safety of the migrated data. For information on configuring multiple copies, see ”Multiple copying” on page 147.

Since tape media wear out over time, some can eventually become unusable. Migrated file generations on such media can no longer be recalled. In effect, this means that one copy of the migrated data is lost. FSE enables you to recover the damaged copy, provided that such data was migrated from an FSE partition for which multiple copying was configured. This process is called recreating a redundant copy and is available for FSE tape media and FSE disk media.

By recreating the redundant copy of the damaged migrated data, you can restore the availability and safety of the migrated data.

The redundant copy recreation process

Redundant copy recreation is started by the fsemedium command and performed by the FSE maintenance job. The process first scans the File System Catalog (FSC) to find the file generations that were migrated to the specified medium, searches for alternative redundant copies in the same or other FSE media pools, and then remigrates data to the FSE media pool of the unreadable medium.

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.
