20080307216 | METHOD AND APPARATUS FOR BOOTING A COMPUTER SYSTEM - 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. | 12-11-2008 |
20090106579 | STORAGE SWITCH SYSTEM, STORAGE SWITCH METHOD, MANAGEMENT SERVER, MANAGEMENT METHOD, AND MANAGEMENT PROGRAM - A switch control system including a storage unit, a switch which logically sets a network topology between the storage unit and a plurality of computers, and a management server which communicates with the switch and the storage unit, wherein the storage unit includes at least one disk; wherein the management server comprises a memory and a processor, wherein the memory holds the network topology which is set by the switch, wherein when a failure is detected in one of the computers currently being used, the processor of the management server refers to the memory to change the network topology for the computer where the failure is detected and another computer which substitutes the computer where the failure is detected, and instructs the switch with the changed network topology so as to cause the switch to logically set the changed network topology, and wherein the management server controls the disk of the computer where the failure is detected to be accessible. | 04-23-2009 |
20090271654 | CONTROL METHOD FOR INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING SYSTEM, AND PROGRAM - An object of the present invention is to ensure, in an information processing system including a plurality of server apparatuses coupled to one another, reliability and availability thereof when failover is executed. In an information processing system, which includes a plurality of server apparatuses coupled to one another, and a management server coupled to the server apparatuses, and is configured to, when detecting occurrence of a failure in an active server apparatus of the server apparatuses, execute failover from the active server apparatus to a standby server apparatus of the server apparatuses after turning on a power supply of the standby server apparatus whose power supply having been turned off, the management server is enabled to: acquire information on the standby server apparatus after turning on the power supply of the standby server apparatus; turn off the power supply of the standby server apparatus after acquiring the information; and, based on the acquired information, judge whether or not failover to the standby server apparatus can be executed. Additionally, an acquisition method of the information can be selected in accordance with an allocated status of the standby server apparatus. | 10-29-2009 |
20090271655 | FAILOVER METHOD, PROGRAM, FAILOVER APPARATUS AND FAILOVER SYSTEM - The invention is to provide a failover method for improving overall reliability of a system including a large number of servers. Priorities set based on operating statuses of respective servers and shared devices capable of communicating with the respective servers in a failover system are stored in a storage portion while the priorities are associated with the respective servers, so that a failure processing portion of a management server retrieves a server based on the priorities and designates the retrieved server as a spare server when a failure occurs in one of the servers. | 10-29-2009 |
20090276511 | CONTROLLING METHOD, COMPUTER SYSTEM, AND PROCESSING PROGRAM OF BOOTING UP A COMPUTER - A computer system having computers executing programs, a management computer managing said computers, and a storage system which can be accessed from said computers via a network, wherein said management computer includes: a storage unit for storing network identity information of said network which is allocated to said computers, application identity information indicating said programs, and area identity information indicating areas in said storage system in which said programs are stored, said network identity information and said area identity information being related to said application identity information, a control unit for sending to said computers said network identity information and said area identity information corresponding to said application identity information, in order to boot programs indicated by said application identity information, in response to entry of a boot request including said application identity information. | 11-05-2009 |
