Abstract: PURPOSE: To provide a device for monitoring the environment of a remote component connected to a host processor by using a standard interface bus having a limited number of address ports and its method. CONSTITUTION: A host adapter 3 contains a bus repeater 4 and a monitoring logic section 5. The section 5 has a bus interface section 8 selectably connected to an interface bus 2 and a host processor 1, a control section 9, and an environment monitoring section 10. The bus repeater 4 has a host interface transceiver 6 connected to the host processor 1 through the interface bus 2 and a drive interface transceiver 7 connected to a storage device 13 through an interface bus 20. The transceivers 6 and 7 are connected to the control section 9 through control lines 11 and 12, respectively.
