Abstract:
A standby server, a first main server, and a second main server to control shared input/output (I/O) adapters in a storage system are provided. The standby server is in communication with the first main server and the second main server, and the storage system is configured to operate as a dual node active system. The standby server is activated in response to receiving a communication from the first main server of a fail mode of the second main server. Systems and physical computer storage media are also provided.
