Abstract: A method provides rebuilding data in a hot spare storage device when multiple storage devices fail in a storage system. The method includes a storage controller determining if a first storage device storing first data has failed within a first group of storage devices. In response to the first storage device failing, the first data is rebuilt in the hot spare storage device from a copy of the first data stored in a first mirrored storage device of the first group of storage devices. In response to a second storage device failing, third data is generated by performing a first exclusive or (XOR) operation with the first data stored on the hot spare storage device and a copy of the second data stored in a second mirrored storage device of the second group of storage devices. The third data is rebuilt in the hot spare storage device. The method recovers original data and prevents complete failure of a virtual disk.

In other embodiments, a method may include determining, by a first IHS, that a second IHS is operating without any OS; and sending, by a first BMC within the first IHS to a second BMC within the second IHS, an access request directed to a virtual drive of the second IHS.

Abstract: A computing environment climate-aware policy management system provides decision support by receiving a request to perform an action, where the request is communicated from or on behalf of a computing resource. Upon receiving the request, an indication of a computing environment climate is obtained, which may include for example, information related to the workflow associated with the requested action, information external to the workflow or other information that contextualizes the computing environment of components thereof. At least one policy is obtained that is associated with at least one of the action associated with the request, the resource associated with the request to perform the action received by the policy system manager, and the indicated climate. Each obtained policy is evaluated and a response to the request to perform the action is provided based upon the results of the policy evaluation.
