A method, computer program product, and computer system for performing, by a computing device, a check on an internal secondary device on a first node during a boot software stack initialization. It may be determined that the internal secondary device is corrupt based upon, at least in part, the check. The first node may access a recovery operating system and an image repository of an internal secondary device on a second node. The internal secondary device on the first node may be rebuilt based upon, at least in part, the recovery operating system and the image repository of the internal secondary device on the second node.

System and method for automated restoration of recovery device

A method of initializing a computing device is provided. The method includes (a) powering up the computing device, (b) initially setting a flag to indicate no need to reboot the computing device, (c) sequentially starting a set of computing components operating on the computing device, (d) in response to one component of the set making a configuration change to the computing device, setting a flag to indicate a need to partially reboot the computing device, and (e) upon all components of the set of components completing to load, partially restarting the computing device conditioned on the flag indicating the need to partially reboot, partially restarting including sequentially restarting the set of computing components without powering up the computing device again. An apparatus, system, and computer program product for performing a similar method are also provided.

Techniques for partially restarting a computing device in response to a configuration change

A method and system for recovering nodes in a hierarchical computer network is disclosed. The operating system of the network detects and exception condition, recovers only the nodes within the scope of the exception condition, and issues I/O requests to nodes during recovery that are not within the scope of the exception condition. The method may involve a computer network system with a plurality of paths connected to adapters on at least one host computer for managing input/output (I/O) requests between the host computer and fibre channel devices, which have a plurality of logical units (LUNs) associated therewith.

Hierarchical recovery method for fibre-channel devices

A host system, such as a server, controls a plurality of different class storage devices on a network. The operating system on the host assigns a unique identification to each storage device using a standard protocol and maintains the identification in the operating system. This allows control of the storage devices without complications even though different classes of devices, using differing identification protocols, are assembled on the same network.
