The document discusses a degraded cluster health status shown in OCUM after adding a cDOT ONTAP controller. While the node pairing status was good, the cluster health showed as degraded. This was because OCUM only marks cluster health as OK after subsystem checks return OK, and one subsystem here showed as degraded, causing the overall cluster health to display as degraded. The solution is to ensure the cluster show and system health subsystem show both return OK.
