Abstract
Methods, apparatus and computer program products implement embodiments of the present invention that enable a controller of a storage device having storage media to perform one or more error recovery operations on the storage media, and to convey, while performing the one or more error recovery operations, a message indicating a status of the one or more error recovery operations to a host processor in communication with the storage device. Storage devices implementing embodiments of the present invention include hard disk drives and solid state disk drives.
Claims17
A storage device, comprising:
- storage media configured to store data;
- and
- a hardware controller having a controller processor configured to perform one or more error recovery operations on the storage media, and to convey, while performing the one or more error recovery operations, a message indicating a status of the one or more error recovery operations to a host processor in communication with the storage device;
- wherein the controller processor is configured to receive, from the host processor, a request to identify the one or more error recovery operations, to convey, in response to receiving the request, a message to the host processor identifying the one or more error recovery operations, to receive, from the host processor, a subsequent request to cancel one of the one or more identified error recovery operations, and to cancel execution of the one of the one or more identified error recovery operations in response to the subsequent request.
A method, comprising:
- performing, by a storage device having storage media, one or more error recovery operations on the storage media;
- and
- conveying, while performing the one or more error recovery operations, a message indicating a status of the one or more error recovery operations to a host processor in communication with the storage device;
- and
- receiving, from the host processor, a request to identify the one or more error recovery operations, conveying, in response to the request, a message to the host processor identifying the one or more error recovery operations, receiving, from the host processor, a subsequent request to cancel one of the one or more identified error recovery operations, and canceling execution of the one of the one or more error identified recovery operations in response to the subsequent request.
A computer program product, the computer program product comprising:
- a non-transitory computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:
- computer readable program code configured to perform, by a storage device having storage media, one or more error recovery operations on the storage media;
- and
- computer readable program code configured to convey, while performing the one or more error recovery operations, a message indicating a status of the one or more error recovery operations to a host processor in communication with the storage device;
- and
- computer readable program code configured to receive, from the host processor, a request to identify the one or more error recovery operations, to convey a message to the host processor identifying the one or more error recovery operations, to receive, from the host processor, a subsequent request to cancel one of the one or more identified error recovery operations, and to cancel execution of the one of the one or more identified error recovery operations in response to the subsequent request.
