Host device with multi-path layer configured for detection and resolution of initiator-related conditions

A method comprising:

• controlling, in a multi-path input-output driver of a host device, delivery of input-output operations from the host device to a storage system over selected ones of a plurality of paths through a network, the paths being associated with respective initiator-target pairs wherein each of the initiators comprises a corresponding one of a plurality of host bus adaptors of the host device and each of the targets comprises a corresponding one of a plurality of ports of the storage system;
• monitoring performance of the ports of the storage system in processing input-output operations delivered thereto;
• detecting an initiator-related condition based at least in part on the monitored performance of the ports;
• and
• automatically adjusting an assignment of one or more of the initiators to one or more of the targets based at least in part on the detected initiator-related condition.

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 a host device comprising a multi-path input-output driver, the host device being configured to communicate over a network with a storage system, causes the host device:

• to control, in the multi-path input-output driver of the host device, delivery of input-output operations from the host device to the storage system over selected ones of a plurality of paths through the network, the paths being associated with respective initiator-target pairs wherein each of the initiators comprises a corresponding one of a plurality of host bus adaptors of the host device and each of the targets comprises a corresponding one of a plurality of ports of the storage system;
• to monitor performance of the ports of the storage system in processing input-output operations delivered thereto;
• to detect an initiator-related condition based at least in part on the monitored performance of the ports;
• and
• to automatically adjust an assignment of one or more of the initiators to one or more of the targets based at least in part on the detected initiator-related condition.
