HOST DEVICE WITH EFFICIENT AUTOMATED SEAMLESS MIGRATION OF LOGICAL STORAGE DEVICES ACROSS MULTIPLE ACCESS PROTOCOLS

摘要

An apparatus comprises a host device configured to communicate over a network with a storage system. The host device establishes a migration session in the host device for migration of a source logical storage device accessible utilizing a first access protocol to a target logical storage device accessible utilizing a second access protocol, and migrates the source logical storage device to the target logical storage device utilizing a multi-path layer of the host device. The multi-path layer maintains separate device identities for the respective source and target logical storage devices in conjunction with the migration session but presents a corresponding composite device having a single device identity to one or more applications executing on the host device. The multi-path layer translates one or more commands directed to the composite device in the first access protocol to one or more commands in the second access protocol.
