US 2014/0195762 A1 · SAFETY FOR VOLUME OPERATIONS

Abstract

A system and method for maintaining the safety of volume operations. A storage controller receives a request to delete a first volume. In response to this request, the storage controller can delete a link between the first volume and its anchor medium. The storage controller can also delay the deletion of the first volume's anchor medium. Later on, if the user wishes to restore the first volume, the storage controller can reconnect the first volume to its previous anchor medium, effectively restoring the first volume to its former state and undoing the deletion operation.

Claims20

Dependent claims

A computer system comprising:

one or more storage devices;
and
a storage controller coupled to the one or more storage devices, wherein the storage controller is configured to:
receive a request to delete a first volume;
responsive to receiving the request to delete the first volume:
responsive to determining a first medium is an anchor medium of the first volume, store an indication that the first volume was previously linked to the first medium;
and
remove any indication that the first volume is valid.

5 more elements

A non-transitory computer readable storage medium storing program instructions, wherein the program instructions are executable by a processor to:

receive a request to delete a first volume;
responsive to receiving the request to delete the first volume:
responsive to determining a first medium is an anchor medium of the first volume, store an indication that the first volume was previously linked to the first medium;
and
remove any indication that the first volume is valid.
