In one embodiment, a method includes retrieving a network parameter for a computing device from a remote server. The method also includes updating data in a registry of the computing device based on the value of the network parameter. The retrieving of the network parameter and the updating of the data in the registry are performed prior to executing an operating system within the computing device.

Boot modification of registry data for iSCSI network boot operations

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.

iSCSI system OS boot configuration modification

In one embodiment, a method includes replicating data in a storage disk. The method also includes storing the data in an Internet Protocol Small Computer System Interface (iSCSI) boot disk that is associated with a diskless iSCSI server. A part of the data, which is related to a device on which the data is executed, is updated during the storing of the data in the iSCSI boot disk.

Boot disk replication for network booting of remote servers

A pre-boot Execution Environment (PXE) boot extension provides a TCP/IP interface via a network interface card of the computerized system. SCSI commands are transported over the TCP/IP connection to provide access to a bootable operating system stored on a second networked computerized system, and the networked computerized system is booted from the bootable operating system stored on the second networked computerized system via the SCSI commands transported over the TCP/IP connection.

iSCSI computer boot system and method

SCSI commands are transported over the TCP/IP connection to provide access to a bootable operating system stored on a second networked computerized system, and the networked computerized system is booted from the bootable operating system stored on the second networked computerized system via the SCSI commands transported over the TCP/IP connection. A network driver is loaded in the booting operating system before the booting operating system's disk driver is loaded.

Modified operating system boot sequence for iSCSI device support

A system includes shared Small Computer System Interface (SCSI) storage devices for processing clients coupled by a fiber channel interface. The storage devices include storage blocks, and locks controlling their use by clients. Clients issue actions to the storage devices for performing operations on the locks. A client may exclude other clients from using storage blocks using a state element to acquire the lock for shared or exclusive use. If the client modified the data, a version counter in the lock is updated when the lock is released. If an activity bit is set, the version counter is updated upon both reading and writing. Other clients can forcibly release a lock owned by a failed client by monitoring its version counter. Expiration timers associated with the locks allow acquired locks to be released by timing out. A serverless global file system (GFS) manages use of the shared storage resources, and allows remapping of the locks to the storage blocks, for example, based on activity of the locks.
