Abstract: Systems and methods for managing a virtual tape library (VTL) domain capable of being coupled to a host are provided. One system includes a plurality of VTL nodes configured to store multiple scratch erased volumes. Each VTL node comprises a processor configured to perform at least a portion of the below method. One method includes receiving a request from the host to de-mount a volume in one of the plurality of VTL nodes, transferring the volume to a scratch category in response to receiving the request, erasing data in the volume and categorizing the volume as a scratch erased volume, and providing ownership of the scratch erased volume to a VTL node in the plurality of VTL nodes based on pre-determined criteria for the plurality of VTL nodes. Also provided are computer storage mediums including computer code for performing the above method.
