2.On the local system, upgrade the operating system.

For a list of supported operating system versions, see the latest support matrices.

CAUTION: Ensure that during or after the operating system upgrade, all LVM volumes on the local system are converted to LVM2 volumes. Failing to convert the LVM volumes to LVM2 volumes may result in loss of the data stored on these volumes.

For information on how to upgrade the operating system and the LVM volumes, see the operating system documentation.

3.If you are upgrading a consolidated FSE system or an external FSE client, update the entry for each HSM file system in the local /etc/fstab file as follows:

a.Invoke the following command, where DeviceFileSymlink is the value from the first column of /etc/fstab for this HSM file system entry:

#ls -laDeviceFileSymlink

The command generates an output similar to the following:

lrwxrwxrwx 1 root root 25 Aug 17 09:12 /dev/vg_fse01/hsmfs01 -> /dev/mapper/vg_fse01-hsmfs01

b.In the local /etc/fstab file, replace DeviceFileSymlink with DeviceFilePathname, where DeviceFilePathname is the device file that the symbolic link points to.

In the above example, the value of DeviceFilePathname is

/dev/mapper/vg_fse01-hsmfs01.

c.In the local /etc/fstab file, comment out the line with the HSM file system entry.

Upgrading the Linux FSE server

To upgrade the consolidated FSE system or FSE server running on a Linux platform, you need to install FSE release 3.4 installation packages over the installed previous FSE product.

Before starting the installation, if the consolidated FSE system or FSE server which you are upgrading has been configured such that the FSE log files have been stored on a separate file system, you need to ensure that this file system is located on an LVM volume.

The following procedure is required, if the file system for FSE log files is not located on an LVM volume:

1.Move the FSE log files to a temporary location on another file system.

2.Configure a new LVM volume for the FSE log files, create a file system on it, and mount the file system to the appropriate directory. For detailed instructions, see the FSE installation guide for Linux, chapter ”Preparing file systems”.

3.Move the FSE log files from the temporary location to the newly created file system.

Installing FSE release 3.4 software on the Linux FSE server

If you are upgrading from a pre-3.4 version to the FSE release 3.4, perform the following procedure to appropriately install the software on the consolidated FSE system or FSE server:

•At the command line, change the current directory to the one with the installation packages. Install all required FSE release 3.4 RPM packages with two invocations of the rpm command. You must pay regard to the proposed order of precedence.

If you are upgrading a consolidated FSE system, invoke the following commands:

# rpm -Fvh fse-common-3.4.0* fse-server-3.4.0* fse-agent-3.4.0* \ fse-client-3.4.0* fse-cli-admin-3.4.0* fse-cli-user-3.4.0*

# rpm -ivh fse-util-3.4.0*

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.
