Connectivity confirmation method for network storage device and host computer

摘要

The present invention decreases the burden of operation required for specifying the connectivity status and the cause of failure of a network storage device. <??>A host computer accepts the specification of the device identifier, that is an identifier of the network storage device in the host protocol which positions in a higher hierarchy than the network communication protocol, and a volume identifier, that is an identifier of the volume. Then based on the specified device identifier, the host computer specifies the network identifier, that is an identifier of the network storage device in the network communication protocol. And connectivity is confirmed in the network communication protocol in which the specified network identifier is the destination. Also connectivity is confirmed in the host protocol in which the device identifier is the destination. And the volume specified by the volume identifier is accessed. <IMAGE>
