Default Gatway for Vmotion

Greetings,

I would like to know if a default gateway is required for setting up Vmotion network, all my vmotion IPs within the same Vlan

Thanks

Yes - its still used for fault determination in split brain scenarios.

Thanks for the reply ... my Vlan was not setup with a default, would the vmotion work if I don't specify the default gateway ?

Thanks

I don't think it will even let you enable the interface without one.

It does and allows you to enable the vmotion port group, also I can ping the Vmotion IP from within the box using vmkping, I guess I will find out once my SAN LUNs available to see if the Vmotion will work without the default gateway, I will keep you posted

Thanks again

For some reason VMotion works in my environment too without default gateway setup on VMKernel port group. We started with ESX 3.0.1 in 2006 and now we are running ESX 3.5. So far VMotion works OK for us.

Yep, I haven't had any issues with it. I think the split brain issue mentioned above would be based on the Service Console address/gateway wouldn't it? HA does not need/use the VMotion IP information I don't think.

If you have no outbound connections to other networks I'm not sure what use a gateway would be anyway...?
