Esxi 5.0 U2 - Port group PNics Rebalance Command?

Hi,

i have 20 VMs on a single Port Group. On this Port Group are connected 6 Phisical Nics.

The VMs are up from a long time, and as far I can see the "Balancing" between

Virtual Nics and Phisical Nics is not optimal.

I have many VMs on 2 NICs, few on 2 Nics and none on 2 Nics.

I know that if i Reboot all the VMs, the "Route based on the Originating Port ID"

algorithm would automatically rebalance all the VM Nics on all the PNics.

There is a way (a command or a script), that can do the complete rebalancing

"Online" without rebooting the VMs?

Thanks
