Abstract
Determining port failover information is described. First information is determined by a first storage processor executing first code for performing port matching. The first information identifies a first set of port pairs. Each port pair includes a first port of the first or second storage processor and a second port of the first or second storage processor. Each port pair denotes the first port as protecting the second port. Upon failure or unavailability of the second port, the first port virtualizes the second port and requests directed to the second port are redirected to the first port. Similarly, second information is determined by the second storage processor executing second code for performing the port matching. Port failover processing is performed upon failure or unavailability of port(s) of the first storage processor and/or the second storage processor. Port failover processing uses the first information and/or the second information.
