Abstract
A method for use in a storage system, comprising: receiving, at a storage processor that is part of the storage system, a notification that an array port in the storage processor is going to be brought offline, transitioning the array port into a first state in which the array port continues to execute in-flight input-output (I/O requests) while rejecting new I/O requests, wherein each rejection includes an upper layer protocol (ULP) response/status message that would cause a sender of the rejection's corresponding I/O request to select an alternative network path that connects the sender to the storage system and re-transmit the corresponding I/O request to the storage system via the alternative network path; and transitioning the array port from the first state into a second state.
