1.Start the fsebackup or fserestore command, specifying the --dbgoption. This will produce additional debug file for the process, besides the ordinary backup.log or restore.log. The debug file is named fse-backup-Number.logor fse-restore-Number.log, respectively, and created in the directory for the debug files.

Linux specific

The debug files are located in the directory /var/opt/fse/log/debug. Windows specific

The debug files are located in the directory %InstallPath%\var\log\debug.

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

Potential problems with debugging

How do I check the debugging level of the HSM file system filter?

Linux specific

Use the command dmesg grep hsmfs_debug to list the HSM file system filter debugging level.

Windows specific

Check the System Event Log (click Start > Settings > Control Panel, double-click Administrative Tools, click Computer Management > Event Viewer).

The HSM file system filter debugging level is always set to 0x0000 after restarting the system

Linux specific

If the HSM file system partition is not listed as noauto in the /etc/fstab file, the HSM file system filter will be loaded at boot time with the debugging level set to 0x0000 regardless of the settings specified in the trace.cfg file.

Resolve the problem as follows:

1.Add the following line into the /etc/modules.conf file: options hsmfs hsmfs_debug=0x007f

where 0x007f is an example of the specified debug level.

2.Restart FSE for the changes to take effect.

Backup or restore debugging results in job failure

Backup and restore debugging using the --dbgoption does not work with the fsesystem --enable-dbgtriggered debugging of FSE processes.

Make sure you turn on debugging of the FSE processes by configuring the trace.cfg file and restarting FSE.

Contacting support

Gathering information about your problem

You need to gather specific information needed for troubleshooting an FSE implementation. Technical support need to know exactly what your problem is and as much information about it as possible. You should describe if any changes were made to the environment before the problem occurred; include software version numbers, the nature of the problem (whether the problem occurs intermittently, what errors are being observed), and a list of third-party vendors.

Checklist for required information

When collecting data about the problem, follow the steps below.

Problem description

Think about the keywords of your problem. Write this down as a one-line description. Specifying what is the real problem is very important, because technical support will focus on solving that precise problem. If

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.
