Method for changing booting configuration and computer system capable of booting OS
First Claim
1. A boot configuration changing method executed by a management server in a computer system in which the management server and a plurality of servers are connected to an external disk drive via a network switch and in which each server can be made operational by booting an operating system from the external disk drive, the boot configuration changing method comprising:
- requesting initiation of synchronization processing between a first disk and a second disk of the external disk drive with respect to a first content of the first disk that is used for booting a first server of the plurality of servers;
changing a setting of a boot program of a second server of the plurality of servers so that the second server is booted from the second disk; and
changing a second content of the second disk so that software installed in the second disk is booted from the second 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.

6. A computer system, comprising:
-
an external disk drive; a management server connected to the external disk drive via a network switch; and a plurality of servers connected to the external disk drive via the network switch, each server of the plurality of servers being configured to be made operational by booting an operating system from the external disk drive, and wherein the management server is configured to request initiation of synchronization processing between a first disk and a second disk of the external disk drive with respect to a first content of the first disk that is used for booting a first server of the plurality of servers, and wherein the management server is configured to direct a first change in a setting of a boot program of a second server of the plurality of servers so that the second server is booted from the second disk, and direct a second change in a second content of the second disk so that software installed in the second disk is booted from the second disk. - View Dependent Claims (7, 8, 9, 10)
