Migration processes utilizing mapping entry timestamps for selection of target logical storage devices

A computer program product comprising a non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code, when executed by at least one processing device comprising a processor coupled to a memory and configured to communicate over a network with a storage system, causes said at least one processing device:

• to maintain a mapping data structure comprising a plurality of mapping entries, each such mapping entry associating an assigned name of a corresponding logical storage device of a storage system with a unique identifier of that logical storage device, a given such mapping entry further comprising a timestamp associated with the logical storage device;
• to identify a source logical storage device for a migration process;
• to access the mapping data structure to determine a timestamp of the source logical storage device and one or more additional timestamps of one or more respective candidate target logical storage devices for the migration process;
• to select based at least in part on the determined timestamps a particular one of the one or more candidate target logical storage devices;
• and
• to initiate the migration process to migrate the source logical storage device to the selected target logical storage device.

A method comprising:

• maintaining a mapping data structure comprising a plurality of mapping entries, each such mapping entry associating an assigned name of a corresponding logical storage device of a storage system with a unique identifier of that logical storage device, a given such mapping entry further comprising a timestamp associated with the logical storage device;
• identifying a source logical storage device for a migration process;
• accessing the mapping data structure to determine a timestamp of the source logical storage device and one or more additional timestamps of one or more respective candidate target logical storage devices for the migration process;
• selecting based at least in part on the determined timestamps a particular one of the one or more candidate target logical storage devices;
• and
• initiating the migration process to migrate the source logical storage device to the selected target logical storage device;
• wherein the method is performed by at least one processing device comprising a processor coupled to a memory.
