Hey there,
I have an HA cluster with three hosts, running fine on the vm network. But for some reason, my third host's vmotion network isn't responding. I can't vmkping the vmotion network, I can't simply ping the vmotion network IP Address I've assigned it either. Here are some things I have tried:
- Physically, I unplugged the NIC and plugged it into an interface on the physical switch that other working vmotion nics for other hosts were plugged into. I could still not ping it, but I could ping the originally working host. So I know there's nothing wrong physically. Lights are fine and blinking. No issues there. To reset the nic itself, I changed the duplexing to something else and then back to 1000 full like the rest of them. I watched as the nic on my host went dark, then lit right back up, orange lights to green lights on my physical switch as well. So I know there's nothing wrong physically.
- I compared everything in config > Networking. All of the hosts are on vSwitch 2, vmk1, same VLAN ID: 30, and have an IP Address on the same subnet (different IPs of course). The properties of the vswitch are exactly the same, because it's the same vswitch for all. And the vmotion port is all the same as well. The network is ONLY used for vmotion, so that's not a problem.
- For resetting things, I haven't fully rebooted the host, but I did update the virtual switch by taking the adapter out of active mode and putting it right back in. I can't think of any other ways to basically reset things.
- During vmotion, trying to move a guest to and from any host on the network will fail after 10% if it is powered up. It tells me it is prepping the vm for live migration, then tells me it's migrating the active state of the vm, then fails with the error : A general system error occurred: the vmotion fialed because the esx hosts were not able to connect over the vmotion network. Please check your vmotion network settings and physical network configuration.
Any ideas at this point? I'm really struggling here. I can't do much because, well, it's the vmotion network.
Thanks in advance!
