HCP for cloud scale performs regular, periodic health verifications to detect storage component failures.

If HCP for cloud scale detects a storage component failure, it sets the storage component state to INACCESSIBLE, so that HCP for cloud scale will not try to write new objects to the storage component, and sends an alert. While a storage component is unavailable, the data in it is not accessible.

HCP for cloud scale continues to verify a failed storage component and, when it detects that the storage component is healthy again, automatically sets its state to ACTIVE. HCP for cloud scale sends an alert when this event happens as well. After the storage component is repaired and brought back online, the data it contains is again accessible and HCP for cloud scale can write new objects to it.
