Abstract
A computer program product may cause a processor to perform various operations. The operations include identifying, via communication with a RAID controller that manages operation of an array of drives as a RAID storage system, one of the drives that has been compromised, a failed component of the identified drive that compromised the identified drive, and a failure domain associated with the failed component, wherein data stored within the failure domain associated with the failed component has become inaccessible. The operations further include instructing, in response to the failed component having a failure domain that satisfies a first condition, the RAID controller to perform a first recovery action that includes regenerating the inaccessible data using data from other drives within the array of drives and storing the regenerated data on available storage of the identified drive outside the failure domain associated with the failed component.
