Abstract:
A method for migrating data in a storage system includes generating a first set of logical disks (LDs), the LDs being mapped to physical storage space in the storage system, generating a temporary virtual volume (VV) mapped to the first set of LDs, generating a second set of LDs mapped to the temporary VV, and migrating data between the second set of LDs and a third set of LDs.
