Recall problems

Description

Device problem is reported after a failed recall. The error message logged in the

 

fse-hsm_ProcessID.log file is the following:

 

Linux specific

 

device busy

 

Windows specific

 

31: A device attached to the system is not functioning.

Explanation

See Workaround.

Workaround

Try to identify the problem as follows:

 

• Determine the status of the corresponding FSE partition with the command:

 

fsepartition --status PartitionName

 

• Check if the fse-hsmprocess is running on the corresponding FSE client.

 

Linux specific

 

Use the ps -ef grep fse-hsmcommand for this purpose.

 

Windows specific

 

Use Windows Task Manager for this purpose.

 

If the partition status is set to any other value than mounted, and the fse-hsmprocess is

 

running on the client, the problem may be caused by an improper configuration of the

 

omniORB.cfg files. For information on which omniORB.cfg settings are correct and how to

 

configure omniORB.cfg appropriately, see ”Reconfiguring FSE interprocess communication”

 

on page 83.

Description

Recall job does not search for alternative copies if the FSE medium is marked 'unusable' after it

 

has been allocated for recall.

Explanation

This may happen in the following situation:

 

• A running FSE recall job has determined from which FSE medium the data will be recalled

 

but is still waiting for that medium to become available (probably because another FSE job

 

has allocated the same medium).

 

• During this waiting time, the medium status is set to unusable but the recall job that is

 

waiting is not notified of this change.

 

The recall job will continue to wait for the medium to become “good” (usable) again, and

 

therefore it will not search for available redundant copies migrated to other FSE media pools, if

 

any exist.

Workaround

Using the fsejob command, identify and terminate all FSE recall jobs that are waiting for the

 

unusable FSE medium to become “good” (usable).

 

If there are redundant copies of the migrated data in other FSE media pools, the subsequent

 

FSE recall jobs will allocate an FSE medium from one of those pools, and recall the data from it.

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.
