Review the best practices for pDRS that are listed here.
Enabling pDRS requires actions to be activated.
The Action credentials must have administrative permissions on the cluster which is enabling pDRS.
pDRS may not be activated for every cluster in vCenter.
vCenter can only receive pDRS data from one vRealize Operations instance.
There must only be one vRealize Operations to one vCenter relationship.
Be careful, if you add another vRealize Operations to the same vCenter
Adding another vRealize Operations to an existing vCenter overwrites the existing vRealize Operations.
Always check pDRS scale numbers
For vRealize Operations, do not activate in clusters > 4K VMs
You need vSphere 6.5 to activate the pDRS functionality
It is required to use vSphere 6.5 to activate the pDRS functionality when using vRealize Operations
