VCHA Deployment error - MethodFault.summary

Hi,

On deployment of the VCHA cluster using the Basic method:

The Peer & Witness nodes are successfully created & Powered On

The 'Deploy a vCenter HA cluster' task fails at approx 84% with a 'MethodFault.summary' status in the Web Client gui.

I've searched the /var/log/vmware/vcha logs for any meaningful errors for the status without success.

I've also tried a re-deploy by destoying the cluster from the VCSA cmd line and re-running the deployment which results in the same state.

This a 6.5 U2c VCSA.

Any ideas or guidance would be appeciated.

Thanks.
