Environment

VMware vSphere 8.x

Cause

The vSphere cluster has an enabled Supervisor that is currently in an error state due to which the vLCM Pre-check fails.

 

Resolution

Fix the Supervisor cluster and make sure that the Supervisor is stable and error-free. 
Rerun the pre-check and remediate the hosts with required build.
