A Pre-boot Execution Environment (PXE) boot extension is loaded upon system boot and is operable to store an iSCSI boot disk identifier identifying a remote disk drive to a shared memory location. As an operating system is loaded via iSCSI over a network connection to a remote disk, an operating system iSCSI driver is loaded. The operating system iSCSI driver reads the boot disk identifier stored in the shared memory location and uses the boot disk identifier to configure the operating system.

A method restores a client device of a network on major failure of the client device. The client device is incapable of automatically booting on its own. The network includes a server computer. The method includes booting the client device over the network in the restoration operation, configuring the client device according to the boot program and saved configuration states for the client device, and copying files to the client device in accordance with the configuration. The client computer has access to a storage manager application, such as a server computer of the network operating a storage management software program. All client files, including configuration files, as well as application and data files, of the client device are saved on the network by the storage manager application. The client device is booted over the network, rather than locally to the client device by boot disk or otherwise. The boot program is loaded to the client device, and the client device retrieves configuration and file information over the network from the storage manager application. The client device configures its disk according to the configuration information, and then all other files and data of the client device at the time of failure of the client device are saved on the disk substantially in the condition and state just prior to the failure and as most recently backed up to the storage manager application. Alternatively, the client device is reset and booted via a control device either locally or otherwise connected to the client device, and substantially according to the method of the network boot.

The reliability is improved at a low cost even in a virtualized server environment.

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.

Described is a technology by which a single physical storage device such as a USB flash memory device is able to boot different computing devices via corresponding different operating systems. The storage device includes a selection mechanism that determines which virtual disk (corresponding to a LUN) is seen by the host as the currently active LUN having sector 0, and therefore is the boot disk. The selection mechanism also may select which (if any) other LUNs are visible to the host. The selection mechanism and accompanying indicator may be operated when the storage device is disconnected, e.g., via manual switches and / or LEDs, buttons and / or a display (e.g., via internal power). Also described is allowing each LUN to have a user-friendly name.

The present invention enables to update a program in a storage control device while processing access requests, without imposing any burden on a host. When execution of updating of a program is commanded from a management terminal, an update control unit starts within the controller which is the object of updating. After a host I / F unit has been connected to an access request processing unit within another controller by a connection control unit, the update control unit updates a program which is stored in a program memory or a boot disk. When this updating is completed, the update control unit reconnects the host I / F unit to its access processing unit by the connection control unit. Since the stored contents of data memories are synchronized, the other access request processing unit can continue processing access requests from the host in place one access request processing unit.
