Patent ID: 7337355

Claim:
A method for processing Input/Output (I/O) requests to a storage network including at least one storage device and at least two adaptors, wherein each adaptor is capable of communicating I/O requests to at least one storage device, comprising: detecting an error in a system including a first adaptor, wherein the first adaptor is capable of communicating on the storage network after the error is detected; determining whether the first adaptor is designated a master of the storage network after the error is detected; starting a master switch timer that is less than a system timeout period if the first adaptor is the master after detecting the error, wherein an error recovery procedure in the system including the first adaptor is initiated after the system timeout period has expired; initiating an operation to designate a 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; initiating a monitoring state to monitor I/O requests transmitted through the second adaptor in response to detecting the error; starting an I/O delay timer that is less than the system timeout period in response to receiving an I/O request; and sending a reset request to the first adaptor in response to detecting an expiration of one started I/O delay timer.
