Method for changing booting configuration and computer system capable of booting OS
First Claim
1. In a computer system in which servers are connected to an external disk drive via a network switch and in which a server can be made operational by booting an operating system from the external disk drive or a built-in disk of each server, a boot configuration changing method for changing a disk used by the server for booting comprising:
- a synchronization step of synchronizing a content of an operation transfer source disk used by the server for booting with a content of an operation transfer destination disk; and
a disk content change step of changing the content of the operation transfer destination disk so that software installed in the operation transfer destination disk is started by using the operation transfer destination disk.

Abstract
In a computer system in which a server has, in addition to a disk used for booting, an operation transfer destination disk that has the same content as the boot disk, a method for changing the disk used by the server or another server in the computer system for booting to the operation transfer destination disk is realized by changing the content of the operation transfer destination disk to enable the OS and applications installed in the operation transfer destination disk to be booted from the destination disk and by changing the setting of a boot program of the server to enable booting from the operation transfer destination disk.

12. In a computer system in which a plurality of servers are connected to an external disk drive via a network switch and in which each of the servers can be made operational by booting an operating system from the external disk drive, a boot configuration changing method for changing a disk used by the server for booting comprising:
-
a synchronization step of synchronizing a content of an operation transfer source disk used by the server for booting with a content of an operation transfer destination disk; and a disk content change step of changing the content of the operation transfer destination disk so that software installed in the operation transfer destination disk is started by using the operation transfer destination disk. - View Dependent Claims (13, 14)

15. A computer system comprising:
-
an external disk drive; a server made operational by booting an operating system from the external disk drive and a built-in disk; a network switch to interconnect the external disk drive and a plurality of servers; and a management server to manage the plurality of servers; wherein the external disk drive includes; an operation transfer source disk used by the server to boot the operating system; an operation transfer destination disk; and a disk synchronization module to synchronize the operation transfer source disk and the operation transfer destination disk; wherein the management server includes; a server management table to record physical positions and states of the plurality of servers; a disk synchronization table to manage a synchronization state of the operation transfer source disk and the operation transfer destination disk; a boot configuration table to manage boot device information of the operation transfer source disk of the server and of the operation transfer destination disk; a boot management function to change a content of the operation transfer destination disk; an agent to change the content of the operation transfer destination disk; and a failover module having a storage management function to request a start and stop of synchronization between the operation transfer source disk and the operation transfer destination disk. - View Dependent Claims (16, 17, 18, 19, 20)
