Performing Disk Volume Reconciliation

Disk volume reconciliation allows you to reconcile the discrepancies in the disk volume associated with a storage policy copy data. This feature compares the physical data located in the disk mount path with the metadata records in the CommServe database and provides the list of orphaned jobs and orphaned media space. Orphaned jobs are jobs without corresponding data on the media, and orphaned media is the list of volumes without corresponding jobs in the CommServe.

You can review the information and delete the orphaned jobs and/or orphaned media. When an orphaned media space is deleted, the space is marked for deletion and pruned based on the retention rules set for the copy. When an orphaned job is deleted, the job is removed from the CommServe database. Jobs deleted using this feature are recorded in the Audit Trail.
