The Health Service constantly monitors your Storage Spaces Direct cluster to detect problems and generate "Faults".
One new cmdlet displays any current Faults, allowing you to easily verify the health of your deployment without looking at every entity or feature in turn.
The Health Service can assess the potential causality among faulting entities to identify and combine faults which are consequences of the same underlying problem.
For now, this functionality is limited to nodes, enclosures, and physical disks in the event of lost connectivity.
For example, if an enclosure has lost connectivity, it follows that those physical disk devices within the enclosure will also be without connectivity.
No additional action is required to set it up or start it.

Recommendation: Check that the physical disk is working and properly connected.
Part: Manufacturer Contoso, Model XYZ9000, Serial 123456789 Location: Seattle DC, Rack B07, Node 4, Slot 11 The physical location is derived from your fault domain configuration.
See the Fault for helpful location and part information.
When the replacement disk is inserted, it will be verified against the Supported Components Document (see the next section).
Physical disks are automatically retired when they can no longer be used, and a corresponding Fault is raised.
There are several cases: If the retired disk was serving as the cache for many other physical disks, these will automatically be reassigned to another cache disk if one is available. Once a physical disk has been retired, the Health Service immediately begins copying its data onto the remaining physical disks, to restore full resiliency.
The health of storage enclosure components such as fans, power supplies, and sensors is derived from SCSI Enclosure Services (SES).
