STORAGE SWITCH SYSTEM, STORAGE SWITCH METHOD, MANAGEMENT SERVER, MANAGEMENT METHOD, AND MANAGEMENT PROGRAM
First Claim
1. 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, whereinthe storage unit comprises at least one disk;
- whereinthe management server comprises a memory and a processor, whereinthe memory holds the network topology which is set by the switch, whereinwhen 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 whereinthe management server controls the disk of the computer where the failure is detected to be accessible from the another computer.

Abstract
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.

2. A switch control method to switch a storage unit using a computer system which comprises 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 comprises 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, comprising steps of; when a failure is detected in one of the computers currently being used, the processor of the management server referring 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 instructing the switch with the changed network topology so as to cause the switch to logically set the changed network topology; and the management server controlling the disk of the computer where the failure is detected to be accessible from the another computer. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)
