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.

Data regeneration and storage in a raid storage system

Systems and methods for implementing maintenance operations on storage devices in place of drive-based maintenance operations are disclosed. According to an aspect, a system includes a storage controller configured to receive a plurality of media scan configurations for maintenance from a plurality of storage devices. The data maintenance algorithms implemented across storage device and storage controller is also configured to tune and/or disable drive-based maintenance routines on one or more of the plurality of storage devices. Further, the BMC and/or storage controller is configured to perform controller-based maintenance operations in replacement of the drive-based maintenance routines of the one or more of the plurality of storage devices based on the received plurality of media scan configurations.
