Changing subnet for VMkernel and Vmotion

[Dave_McD]

Our current setup has Vmotion on the same subnet as our production machines, which I am not happy aboutand it is causing our 3com switched trouble when we vmotion a VM.

We have dedicated a subnet to vmotion and want to change the vmkernel port to the new subnet.

Our current vmkernel port has 2 physical nics, 1 in standby mode.

My plan is to create another vmkernel port on the same switch and the standby NIC. I would enable vmotion on that one, then disable vmotion on the original one.

I would then delete the original vmkernel port.

Will this plan work and if so, what sort of network out age will I be looking at.

Finally, is there a better way I can do it?

If you're not using IP storage, no problems.

Evening,

This is actually how we run our Service Console and VMotion. We have both Service Console and VMotion on one vSwitch. The Service Console port group is configured with 1 network adapter active and 1 standby. The VMotion port group is configured in reverse. This separates the traffic out while still giving you a level of redundancy in case a network adapter/cable goes down.

Since you are adding VMotion to an existing vSwitch (vswif0) then will be no outage, unless as the other poster said you have IP storage.

Kind regards,

Glen
