Abstract: When the main power source is turned on, a storage system creates a revision table for storing the revision of main firmware installed in a resource management processor of the storage system. Next, the main firmware is loaded from a system drive into a cache memory. When the revision of the main firmware installed in the resource management processor is old, this main firmware is renewed to the main firmware loaded into the cache.

Abstract: The present invention provides a photoreduction method for metal complex ions by which strict controllability is not required in the control of its exposure amount, and a size of the metallic structure to be produced can be controlled, besides there is no fear of reducing spatial resolution of the size of the metallic structure to be produced. The photoreduction method for metal complex ions wherein a laser beam is beam-irradiated on a metal complex ion dispersion element dispersed in a material to photoreduce the metal complex ions thereby fabricating a metallic structure, includes the steps of adding a predetermined coloring matter to the material in which the metal complex ion dispersion element is dispersed, and beam-irradiating the laser beam to the material to which the predetermined coloring matter has been added.

Abstract: A storage control system comprises a first controller connected through a first access route to a first storage; a second controller connected through a second access route to a second storage device; a third controller connected through a third access route to the first storage device; and a fourth controller connected through a fourth access route to the second storage device. For example, if the access destination in accordance with the access instruction received from the host device is the second storage device, the first controller outputs an access request to the second controller. The second controller accesses the second storage device through the second access route in accordance with this access request.

Abstract: A registered address that is normally used by the user and comprises personal information is input into an MFP apparatus. The MFP apparatus sends a command including the registered address to the mail provider, obtains a new address for which the registered address is designated as a forwarding address, and deletes the registered address from the MFP apparatus. Where the MFP apparatus receives an e-mail non-arrival notification, the MFP apparatus sends the non-arrival notification to the new address. The non-arrival notification sent to the new address is received by the mail provider and forwarded to the registered address. In this way, notification of the e-mail's non-arrival can be provided without the registered address remaining in the MFP apparatus.

Abstract: A subsystem and a subsystem processing method are disclosed in which a storage control unit 2000 interposed between a plurality of disk units 3000 and a host computer 1000 has a nonvolatile cache 2400 for temporarily holding the read data/write data exchanged between the disk units 3000 and the host computer 1000. The management information for the user data in the cache 2400 is stored in both the in-cache management information area 2420 in the cache 2400 and the in-memory management information area 2221 in a volatile local memory 2210 accessible at high speed. Under normal conditions, the management information in the high speed in-memory management information area 2221 is accessed. At the time of a fault, on the other hand, the management information in the nonvolatile in-cache management information area 2420 is restored in the in-memory management information area 2221, thereby improving the access rate of the cache 2400.
