ABSTRACT:
In order to avoid location of a buffer or a cache memory required for recovering a path trouble in the conventional storage unit, a new switch is provided between a computer and a storage unit. This switch manages a command to be relayed thereby, transmits to the computer an error response if the switch detects a trouble, and at a time changes a setting so that the subsequent commands may be transmitted through an alternate path.
