Abstract
Disclosed herein is a computer system provided with a mechanism for connecting a single port disk to an active server and the disk to a standby server when in a fail-over processing. An “add_pci” command issued from a clustering program is used to let a control program change the allocation of a PCI slot while an interruption signal issued to a standby server permits an ACPI processing routine to hot-add a PCI card that includes the disk unit on the subject guest OS.
