Abstract
An apparatus comprises a host device configured to communicate over a network with a storage system comprising a plurality of storage devices. The host device is configured to implement a multi-path input-output driver for delivery of input-output operations from the host device to the storage system over the network. The multi-path input-output driver is configured to perform, in user space of the host device, discovery of paths to logical storage volumes of the storage system, to identify two or more of the paths providing connection to a given one of the logical storage volumes, to generate, in the user space of the host device, a given multi-path logical device grouping the identified two or more paths providing connection to the given logical storage volume, and to submit input-output operations directed to the given logical storage volume via the given multi-path logical device in the user space of the host device.
