Abstract
A storage device according to an embodiment of the present invention has a plurality of storage nodes, each of which has a plurality of logical ports having send and receive queues for a communication request and an identification number, and an internal network for connecting the plurality of storage nodes with one another. The storage nodes each have, as the logical ports, a data communication logical port used for data communication with other storage nodes and an error communication logical port used to notify the other storage nodes of a state of the data communication logical port. When detecting an occurrence of transition of the data communication logical port to an error state, the storage node uses the error communication logical port to notify the other storage nodes of the identification number and the state of the data communication logical port.
