Partition Manager processes (fse–pm) for all configured FSE partitions must be running. This can be checked with the fsesystem command.

After successful command execution, fsebak notifies the FSE administrator with a suitable message, which is printed to the standard output stream (stdout). If there was an error during command execution, an appropriate error message is printed to the standard error stream (stderr).

ACHIEVING THE FSE DATABASE CONSISTENCY fsebak – –suspend

follows for each running Partition Manager the following procedure:

•block the incoming job requests in Partition Manager;

•make the corresponding HSMDB and FSC incorporate all changes from their transaction logs into the main database files;

•write temporary files hsm.ref and fsc.ref with references to HSMDBs and

FSCs for use with the – –continueoption;

• report action success or failure.

Note:

Contents of hsm.ref and fsc.ref files should not be directly altered in any way.

If all these steps are successfully completed, duplicate copies of HSMDBs and FSCs can be made.

RESUMING NORMAL FSE SYSTEM OPERATION fsebak – –continue

StatusCode follows for each running Partition Manager the following procedure:

•read references to HSMDBs and FSCs from files hsm.ref and fsc.ref ) and delete these two files;

•start accepting incoming job requests in Partition Manager and resume nor- mal operation.

If the value 0 (zero) is used in place of the StatusCode argument, all old transaction log files of HSMDBs and FSCs are removed, as the assumption is they will not be needed any more. If any other value is used as the StatusCode, these transaction logs are preserved for a potential future use.

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.
