Self-healing hard disk drive system

An Information Handling System (IHS), comprising:

• a processing system;
• and
• a memory system that is coupled to the processing system and that includes instructions that, when executed by the processing system, cause the processing system to provide a Hard Disk Drive (HDD) device self-healing engine that is configured to:
• reserve a first HDD data storage resource, which is included in a plurality of HDD data storage resources that are included in an HDD data storage system in an HDD device to configure the first HDD data storage resource as a reserved first HDD data storage resource that is not used to store data for the HDD data storage system;
• report, to the HDD data storage system, a total HDD storage capacity provided by the HDD storage capacities of the plurality of HDD data storage resources without the reserved first HDD data storage resource;
• determine that data storage operations using a second HDD data storage resource that is included in the plurality of HDD data storage resources will be subsequently unavailable;
• remap logical addresses associated with the second HDD data storage resource to the first HDD data storage resource to configure the first HDD data storage resource to store data for the HDD data storage system;
• report, to the HDD data storage system, the total HDD storage capacity provided by the HDD storage capacities of the plurality of HDD data storage resources including the first HDD data storage resource and without the second HDD data storage resource such that the total HDD storage capacity reported to the HDD data storage system remains constant;
• and
• provide the data that was stored using the second HDD data storage resource on the first HDD data storage resource.

A method for self-healing a Hard Disk Drive (HDD) device, comprising:

• reserving, by a Hard Disk Drive (HDD) device, a first HDD data storage resource, which is included in a plurality of HDD data storage resources that are included in an HDD data storage system in the HDD device to configure the first HDD data storage resource as a reserved first HDD data storage resource that is not used to store data for the HDD data storage system;
• reporting, by the HDD device to the HDD data storage system, a total HDD storage capacity provided by the HDD storage capacities of the plurality of HDD data storage resources without the reserved first HDD data storage resource;
• determining, by the HDD device, that data storage operations using a second HDD data storage resource that is included in the plurality of HDD data storage resources will be subsequently unavailable;
• remapping, by the HDD device, logical addresses associated with the second HDD data storage resource to the first HDD data storage resource to configure the first HDD data storage resource to store data for the HDD data storage system;
• report, to the HDD data storage system, the total HDD storage capacity provided by the HDD storage capacities of the plurality of HDD data storage resources including the first HDD data storage resource and without the second HDD data storage resource such that the total HDD storage capacity reported to the HDD data storage system remains constant;
• and
• providing, by the HDD device, the data that was stored using the second HDD data storage resource on the first HDD data storage resource.
