Abstract
Techniques for detecting and managing target port overloads due to host initiator or path failures may include: receiving I/Os from initiators of a host at target ports of a data storage system; determining initiator workloads for the initiators; determining target workloads for the target ports; determining that a first of the initiators of the host is a failed initiator that has stopped sending I/Os to the data storage system, wherein the first initiator has a first of the initiator workloads; determining, in accordance with the first initiator workload, revised target workloads for the target ports; determining, in accordance with revised target workloads, whether any of the target ports is expected to be overloaded; and responsive to determining that at least one of the target ports is expected to be overloaded, performing a corrective action to alleviate or reduce an overloaded workload condition expected for the at least one target port.
