Abstract

Systems and methods presented herein provide for recovering a failed expander in a data storage switch to restore the switch to optimal. In one embodiment, a data storage switch includes a master expander having a first firmware module operable to link a plurality of logical volumes to at least one initiator through a first plurality of physical transceivers. The data storage switch also includes a slave expander having a second firmware module operable to link the plurality of logical volumes to the at least one initiator through a second plurality of physical transceivers. The slave expander is operable to detect a firmware failure of the master expander to link at least a portion of the logical volumes to the at least one initiator, to load a copy of second firmware module into the master expander, and to initiate the master expander to link to the logical volumes to the at least one initiator through the first plurality of physical transceivers based on the copy of the second firmware module.
