vSAN Health Service - Physical Disk Health - Operation Health

(9 days ago) WEBDying Disk Handling (DDH) in vSAN continuously monitors the health of disks and disk groups in order to detect an impending disk failure or a poorly performing disk group. When such conditions are detected, vSAN marks the disk or disk group as unhealthy and might trigger data evacuation from the affected disk or disk group.
