Abstract:
A method that includes identifying a failure indication for a first data storage device that is a member of a first RAID group within a storage array. The method further can include, via a processor external to the storage array, identifying a virtual drive that is defined to include at least one logical storage volume defined in a second RAID group. The virtual drive can be provisioned to serve as a virtual hot spare within the first RAID group to replace the first data storage device.
