The processing device is configured to control delivery of input-output (IO) operations from a host device to at least one storage system over selected ones of a plurality of paths through a network, and to detect initiation of a non-disruptive upgrade of the host device. The processing device is further configured to identify, responsive to the detected initiation, one or more of the plurality of paths that will become temporarily unavailable in conjunction with the non-disruptive upgrade, and to modify path selection in the host device to avoid selecting the identified paths for at least a portion of a time period during which the non-disruptive upgrade is in progress. The processing device illustratively comprises at least a portion of the host device, including a multi-path input-output (MPIO) driver that performs at least a portion of the detection, identification and modification."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Path selection modification for non-disruptive upgrade of a host device","description":"An apparatus comprises at least one processing device that includes a processor coupled to a memory.
