2.on system volume on FSE media (fast method),

3.at the end of each data volume on FSE media (slow method).

If FRI is missing and none of the above methods can be used, the procedure reverts to recovering from migrated metadata (the slowest method). If even this method fails, the recovery process is stopped and an appropriate error is written to FSE error.log.

Recovery uses all available FSE drives for accessing multiple volumes at the same time in order to speed up the recovery operation. The FSE partition for which File System Catalog recovery is running is blocked for file accesses and all incoming jobs.

IMPORTANT: If FSE processes are stopped during the recovery operation, re- covery will continue after the FSE processes will be started again.

HSM FS RECOVERY PROCEDURE An HSM file system is regenerated from the Name Space Catalog (NSC), which holds all necessary information about the HSM file system.

To recover an HSM file system from scratch the administrator has to:

1.unmount the inconsistent HSM file system

2.format the HSM file system

3.unmount the empty HSM file system (on Windows FSE clients only)

4.start recovery of the HSM file system

Recovery job can be stopped with the command:

 

 

 

fsejob –a <JobID>

 

 

 

If

recovery of HSM file system is started again

it

will resume recov-

ery

from the last recovered file ID. That file ID

is

retrieved

from the

file

/var/opt/fse/tmp/.<PartitionName>_hsmfs_recover

(on Linux

systems) or

%Installpath%\var\tmp\.<PartitionName>_hsmfs_recover (on Windows sys- tems).

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.
