In investigating the cause of a fault in a computer storage system, it is considered useful to previously prepare maintenance logical units (LUs) of a simple structure, the operation of which has been confirmed. If the same number of LUs as servers are prepared for each server as in the prior art, the efficiency is low. Furthermore, securing these LUs complicates assignment of the LUs for construction of a system and a work for addressing the fault. The present invention provides a computer system free of these problems. The computer system has a first computer for executing a first OS (operating system), a second computer for executing a second OS, and a storage array system. The storage array system uses a disk device having a logical unit (LU) for storing a boot loader, as well as the first and second OSes. The boot loader is executed on any one of the two computers, reads in any of the OSes corresponding to the currently operating computer into this operating computer, and executes the read OS.

When a failure is detected in a server currently being used, a management server changes the network topology for the server currently being used and another server which substitutes the server. Then, the management server instructs the network SW with the changed network topology so as to cause the network SW to set the network topology logically. In addition, the management server instructs a disk array unit to control accesses from the other server to the disk in accordance with the server where the failure is detected.

Respective WWNs (World Wide Names) which can be allocated to a plurality of computers, business application identity information of programs to be booted and area identity information, of areas in a storage system in which the programs are stored, are associated and stored. In response to the entry of a boot request including the business application identity information of a designated computer to be booted, the WWN and the area identity information corresponding to the business application identity information are sent to the computer in order to boot the program. In the computer, the sent WWN is set and the area identity information is set as the area to be booted. Subsequently, by means of a restart of the computer, the program stored in the area is booted to operate.

摘要:
An optical scanning device of the present invention includes a simple scanning lens. At least one of opposite surfaces of the lens has a nonarcuate shape, as seen in a polarization plane. At least one of the opposite surfaces is a special toric surface. Further, in a plane perpendicular to the polarization plane, the lens has a meniscus shape concave toward a polarizer. With this configuration, the lens achieves a desirable uniform velocity scanning capability and a desirable field curvature in the main scanning direction. The lens is therefore free from errors in configuration ascribable to molding while reducing the limitation on the tolerance of optical elements in the optical axis direction as to assembly.
