  • Locate the "vcsHealthStatus" field in the summary table. The value should be "healthy".

• vCLS Health not reported

Environment

vCenter Server 8.x

Cause

vCLS health change happened at very early stage of vpxd initialization, and at that point the event system was not properly initialized. The vCLS healthy event was missed.

Resolution

1. Set DRS to Manual.
2. Confirm no HA or DRS tasks occurring.
3. Enable vCLS retreat mode (this will disable vCLS), see KB: Disable vCLS on a Cluster via Retreat Mode
4. Confirm all tasks for the cluster vCLS VMs have completed (e.g., power off, delete, etc.).
5. Enable System Managed (this will enable vCLS), see KB above. 
6. Verify vSphere Cluster Services health shows Healthy status.
7. Set DRS to original setting.
