A disk failure has occurred in a vSAN cluster.

Checking the vSAN Health Service in the vSphere Client is the first step in diagnosing the issue and verifying the status of the vSAN components after the disk failure.

Rebuilding the affected disk group is necessary to ensure that data is re-optimized and replicated in accordance with the vSAN policy.

Replacing the failed disk with a new one ensures that the storage capacity is restored.

Ensuring that the new disk is claimed by the vSAN cluster is important to ensure that it is recognized and integrated into the vSAN disk group.
