The status of the medium can be one of the following:

uninitialized

The medium must be initialized before it can be used.

free

The medium has been initialized, but no user data is stored on it

 

yet.

in use

The medium is currently in use.

open

Medium volumes are not full yet and Fast Recovery Information

 

is stored on disk only

full

Medium volumes are full and Fast Recovery Information is

 

already written on the medium.

Additionally, if FSE detects errors on a medium, the medium status is set to one of the following:

unreliable

The medium is considered for recall only.

unusable

The medium is not considered for any read/write operation.

After you have checked the medium and determined its current condition:

•If it is corrupted, remove it.

•If the error was fixed, mark the medium as fully available. For details, see ”Putting an FSE medium back into use” on page 120.

Checking the status of a particular medium

Once you know the medium barcode, you can narrow your search and view the status of the selected medium volume by using the --listoption, followed by the medium barcode and the --volumeoption.

As shown in the example below, the output is the following:

•medium barcode

•volume

•volume type

•size

•available space in GB

•usage in percentage

•medium volume status

If the status is closed, medium volumes are full and Fast Recovery Information is already written on the medium. If the status is open, medium volumes are not full yet and Fast Recovery Information is stored on disk only.

Example output of the fsemedium --list --volume command

fsemedium --list

000045 --volume

Changing the condition status of media

The Resource Management Database recognizes three kinds of statuses which address a medium condition: “good” (any of the statuses in which the medium is usable), unreliable, and unusable. Typically, the latter two are used whenever FSE detects errors on a medium. Such a medium is then automatically marked appropriately as either unreliable or unusable.

The FSE implementation provides an option to use the medium status for preventing further use of specified media without having to put them off-site, and then to change their status back to be fully available.

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.
