Patent ID: 8909980

Claim:
A method for coordinating processing to redirect requests comprising: providing a first storage processor and a second storage processor of a data storage system, said first storage processor having requests directed to a first set of one or more physical target ports of the first storage processor, said second storage processor being unavailable and having a second set of one or more virtual target ports, each virtual port of the second set being virtualized by one physical port of the first set whereby requests directed to said each virtual port are directed to the one physical port of the first storage processor; and performing first processing to redirect requests from the second set of virtual ports to a third set of one or more physical ports of the second storage processor, said first processing including: booting the second storage processor; directing requests to the third set of one or more physical ports of the second storage processor rather than to the second set of one or more virtual ports; and queuing requests received at the third set of one or more physical ports until completion of pending requests previously received at the second set of one or more virtual ports whereby the pending requests are being serviced by the first storage processor.
