you describe a wrong problem, you might end up with the original problem still present after technical support have already put significant effort into investigating and finding a solution to another problem.

Log and debug traces of the problem

Reproduce the problem with debugging enabled — for details, see ”Debugging FSE processes” on page 275. Save the evidence, such as wrong command output or strange error messages, and send it for lab investigation.

Note that without knowing the contents of the fse.log and error.log files, technical support cannot start investigating the problem.

Reproduction procedure

Write down the procedure for reproducing the problem. This is important for technical support to be able to investigate and solve the problem.

Workaround discovered?

If you managed to develop your own workaround, describe it and add the description as a part of your problem report. It might be a useful hint to technical support and other users, or it can lead to an even better solution.

System information

Linux specific

Use the /opt/fse/sbin/tools/fse_sysinfo.sh script to collect data about the system the FSE software is running on. The output is shown on stdout, and stored in the file /var/opt/fse/log/Hostname_info.log. Send this file and the contents of the directory /var/opt/fse/cfg to technical support.

Windows specific

Use System Information to collect data about the system. Click Start > Programs > Accessories > System Tools > System Information to open System Information. From the Action menu, select the Save As System Information option and send the file to technical support.

One archive package

Pack everything collected in previous steps into a .tar file (on Linux platform) or .zip file (on Windows platform). It is easier to handle one file per problem. This way you make sure technical support receive everything you provide for problem investigation.

Contact

See ”HP technical support” on page 8.

Technical support will contact you as soon as possible, depending on the data you provide and especially on the problem you reported.

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.
