I am fairly new to vvol deployment from Pure

Was wondering what I might be doing wrong when attempting to attach a vvol to additional hosts. I have the host group in question added to the protocol endpoint, but when adding the hosts on the vsphere side, I keep getting an HA error: (vSphere HA failed to create a configuration vVol for this datastore and so will not be able to protect virtual machines on the datastore until the problem is resolved. Error: Operation failed, diagnostics report: .vSphere-HA (Cannot Create File)). disabling and re-enabling HA doesn't clear the error.
