6 Upgrading from previous FSE releases

In this chapter, you will be instructed how to upgrade an FSE implementation that currently uses a previous FSE product version to release version 3.4. Upgrading will add the new functionality that has been implemented in the new FSE release, and install the FSE utilities: HSM Health Monitor and Log Analyzer. The upgrade procedure will preserve the current state of the FSE implementation, including its configuration, all migrated data on FSE media, a complete state of all HSM file systems and FSE databases and system files.

For a list of previous FSE products that can be upgraded to the new release, see the FSE release notes, chapter ”Supported hardware and software”, section ”Supported upgrade paths”.

For information on how to upgrade or install the third-party software packages, see the third-party software documentation and the operating system documentation.

•Make sure that you also have the following available:

• FSE installation guide for Windows

This is required, since while upgrading, you may also need to follow instructions provided in the above manual, depending on the platforms on other systems that are included in your FSE implementation.

•Additionally, make sure you have the following available, depending on the Linux distributions installed on the Linux FSE hosts:

•SUSE Linux Enterprise Server 9 documentation

•Red Hat Enterprise Linux 4 documentation

This is required for correct operating system upgrade on these hosts.

•You must be logged on to the system as root in order to execute shell commands.

Upgrade overview

To upgrade an FSE system, perform the following procedure. Most of the steps from the procedure are described in detail in the sections that follow:

1.If the FSE Management Console is installed in the FSE implementation, stop the FSE Management Console server and the FSE Management Console client processes.

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.
