We also use CommVault and I checked my 5.5 vCenters, they are only listening on 902/UDP as well. For the deployment of a VCH to succeed, port 2377 must be open for outgoing connections on all ESXi hosts before you run vic-machine create to deploy a VCH. After much troubleshooting, thinking that the firewalls were the issue, but were not as we killed off all firewalls on the affected devices with no change.we noticed that the VC was not listening on port TCP 902.it is listening on UDP 902 though.
