VMware Replication only working one direction

Jump to solution

I am trying to get VMware Replication running in my test/dev environment.

Environment

ESXi 6.7U3

vCenter: 6.7.0 14368073

VMware Replication:  8.2.0 14761900

Two physical ESXi hosts connected back to back, ie: no firewalls or network devices in the way.

Deployed via vCenter web client OVF install.

Issue

I have redeployed the appliances multiple times with the same result.

I can successfully replicate VMs from site B to site A, but I can't do it the other way round.

The replication job from Site A just sits in a "Not Active" state.

Troubleshooting

I've read though multiple forums/websites that describe the common Replication issues.   I have ensured:

  1. Full network connectivity between the two sites is available.
  2. All the required VIBs are loaded on the ESXi servers (I did see VMware Knowledge Base )
  3. The ESXi firewall ports are enabled for "Replication-to-Cloud Traffic"
  4. Both replication appliances can see each other and show the status as connected.
  5. vCenter on both sides shows the Replication appliances as connected.

I can't see any obvious errors in the ESXi or Replication Appliance logs (perhaps I'm not looking for the right thing).

At this stage, I can't think of anything else to check, so suggestions are most welcome.

After further investigation, I've discovered that the ESXi server on Site A can't talk to Site B.

I thought I'd verified all network connectivity, but obviously missed this one.    Just have to work out what's stopping the traffic and I'm confident the replication will all start working after that.
