Abstract
An apparatus in one embodiment comprises a host device configured to communicate with a storage system. Responsive to an instruction to migrate data from a source volume to a destination volume, the host device replaces an input-output entry function of a source pathing device associated with the source volume with a migration input-output entry function that is configured, in response to receiving an input-output operation, to call an input-output entry function of a destination pathing device associated with the destination volume and to call the input-output entry function of the source pathing device. Responsive to an indication that a migration of data has completed, the host device replaces the migration input-output entry function with a post-migration input-output entry function. The post-migration input-output function is configured to call the input-output entry function of the destination pathing device in response to receiving an input-output operation.
