Multihome vcenter 6.0 issue

[gferreyra]

Hello guys.

What about a vcenter with 2 different IPs (primary vlan: 10.10.1.2/24, gw: 10.10.1.1; and secondary vlan: 192.168.1.2/24), which ESXi hosts take as vcenter managed ip, either of them?

All the ESXi hosts are on 192.168.1.x/24. Some of the ESXi hosts, once you add them to vcenter, have heartbeat issues (you can the the timeouts on vcenter vpxa log), because the “serverIP” variable on /etc/vmware/vpxa/vpxa.cfg points to 10.10.1.2, instead of 192.168.1.2.

VMware support does not how to fix this. All they say is that multihome is not supported.

I’ve tried everything.

Any idea?

Multihoming of vCenter isn't supported until 7.0, so if GSS is telling you it's not supported on your version, why are you still trying to do it?

Multihome support came with vSphere 7.0. So unfortunately you can't do this.

You can write a route to vCenter Server. However, it will definitely cause errors and problems during the update / upgrade process.
