摘要： When a primary computer is taken over to a secondary computer in a redundancy configuration computer system where booting is performed via a storage area network (SAN), a management server delivers an information collecting/setting program to the secondary computer before the user's operating system of the secondary computer is started. This program assigns a unique ID (World Wide Name), assigned to the fiber channel port of the primary computer, to the fiber channel port of the secondary computer to allow a software image to be taken over from the primary computer to the secondary computer.

摘要： A semiconductor element 100 including an MISFET according to the present invention is characterized by having diode characteristics in a reverse direction through an epitaxial channel layer 50. The semiconductor element 100 includes a semiconductor layer 20 of a first conductivity type, a body region 30 of a second conductivity type, source and drain regions 40 and 75 of the first conductivity type, an epitaxial channel layer 50 in contact with the body region, source and drain electrodes 45 and 70, a gate insulating film 60, and a gate electrode 65. If the voltage applied to the gate electrode of the MISFET is smaller than a threshold voltage, the semiconductor element 100 functions as a diode in which current flows from the source electrode 45 to the drain electrode 70 through the epitaxial channel layer 50. The absolute value of the turn-on voltage of this diode is smaller than that of the turn-on voltage of a body diode that is formed of the body region and the first silicon carbide semiconductor layer.
