Abstract
Described are techniques for coordinating processing to redirect requests. First and second storage processors of a data storage system are provided. Requests are directed to a first set of physical target ports of the first storage processor. The second storage processor is unavailable and has a second set of virtual target ports. Each virtual port of the second set is virtualized by a physical port of the first set. First processing is performed to redirect requests from the second set of virtual ports to a third set of physical ports of the second storage processor. First processing includes booting the second storage processor, directing requests to the third set of physical ports of the second storage processor rather than second set of virtual ports, and queuing requests received at the third set of physical ports until completion of pending requests previously received at the second set of virtual ports.
