HP File System Extender (FSE) guide

Use the rpm -Vcommand to check whether the software installation is corrupt. Note that applied FSE hot fixes change individual binaries and other files making it difficult to determine whether or not the installation is corrupt. Proceed as follows:

1.Change the current directory to one with the FSE installation packages and reinstall the packages:

#cd PathToFSEPackageDirectory

#rpm -F --force fse*.rpm

2.Verify the reinstalled packages using the following command:

#rpm -V `rpm -qa grep fse`

If all FSE release or FSE system maintenance release files were correctly updated, the command output is empty.

Preparing the environment for the first startup of the FSE implementation

Preparing the environment consists of modifying environment variables, updating the FSE backup configuration files, and configuring the FSE interprocess communication.

Modifying the PATH environment variable

To be able to execute FSE commands, FSE tools, the omninames command, and start the FSE Management Console client from any location, change the search path as follows:

# export PATH=$PATH:/opt/fse/sbin:/opt/fse/sbin/tools:/opt/fse/bin

You can permanently extend the executable search path by adding the above line to your .bashrc shell startup file. The changes in .bashrc become effective after your next logon to the system as root.

Modifying the LD_LIBRARY_PATH environment variable

To enable Log Analyzer to run, set the variable for paths to shared libraries as follows:

# export LD_LIBRARY_PATH=/usr/local/lib

You can permanently extend the executable search path by adding the above line to your .bashrc shell startup file. The changes in .bashrc become effective after your next logon to the system as root.

Modifying the MANPATH environment variable

To read the FSE man pages, extend the search path for man pages as follows:

# export MANPATH=$MANPATH:/opt/fse/man

You can permanently extend the man page search path by adding the above line to your .bashrc shell startup file. The changes in .bashrc become effective after your next logon to the system as root.

Preparing the FSE backup configuration file

Configure the parameter SNAPSHOT_PCT in the backup configuration file /etc/opt/fse/backup.cfg.

The line from backup.cfg with SNAPSHOT_PCT configured with its default value is the following:

SNAPSHOT_PCT=10

For details, see the FSE user guide, chapter ”Backup, restore, and recovery”, section ”Backup”, subsection ”How it works?”.

Configuring the FSE interprocess communication

FSE interprocess communication is configured according to the FSE implementation (consolidated, distributed, or mixed FSE implementation) and the network type used for FSE interprocess communication (ordinary LAN, private network). In this context, the term ordinary LAN means the common company LAN to which systems are attached using their primary network adapters, and the term private network means a dedicated network to which systems are attached using their secondary network adapters.

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.
