Abstract:
1. A system for processing Input/Output (I/O) requests to a storage network including at least one storage device and a system including a first adaptor capable of communicating I/O requests to at least one storage device, wherein the system including the first adaptor initiates an error recovery procedure after a system timeout period has expired, comprising: a second adaptor capable of communicating on the storage network; means for detecting an error in the system including the first adaptor, wherein the first adaptor is capable of communicating on the storage network after the error is detected, and wherein the detected error indicates that the first adaptor is unable to communicate to the system including the first adaptor; means for determining whether the first adaptor is designated a master of the storage network after the error is detected; means for starting a master switch timer, after detecting the error, that is less than the system timeout period if the first adaptor is the master; and means for initiating an operation to designate the second adaptor in the storage network as the master if the first adaptor is the master in response to detecting an expiration of the master switch timer.
