Techniques for rebooting a node may include: performing first processing that fails to reboot the node using a primary storage device of the node; responsive to the first processing failing to reboot the node using the primary storage device of the node, performing second processing that reboots the node using a secondary storage device of the node and executes a recovery operating system of the secondary storage device; determining, by the recovery operating system executing first code, whether the primary storage device of the node meets one or more criteria indicating that the primary storage device is faulty or defective; and responsive to determining the primary storage device of the node meets the one or more criteria, performing third processing that restores the primary storage device using the secondary storage device.

Techniques for software recovery and restoration

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

Described are techniques for request processing. A request may be received from a requester for first data to be returned to the requester. The request may be in accordance with an application programming interface. The first data may include a plurality of objects each including a value for a first property. The request may include a parameter of the application programming interface indicating to return the plurality of objects sorted in accordance with natural ordering based on the first property of each of the plurality of objects. The natural ordering may be performed as the default ordering. With natural ordering, one or more consecutive digits in a string are treated as a single numeric value rather than individual characters. First processing may be performed to service the request and obtain the first data. A response, including the first data, may be generated in accordance with the first processing.

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, computer program product, and computing system for executing an upgrade procedure on a data storage system that includes a plurality of storage targets. One or more upgradable storage targets, chosen from the plurality of storage targets, are identified that are eligible for a firmware upgrade. A current firmware file is obtained for each of the upgradeable storage targets. The current firmware file is installed on each of the upgradable storage targets.
