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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for managing raid storage system having a hot spare drive","description":"A method provides rebuilding data in a hot spare storage device when multiple storage devices fail in a storage system.
