VMware 4.1 - Is it possible to do automatic migration of VM's across hosts when LUN is near full capacity

Hi All,

We have VMware 4.1 - Is it possible to  do automatic migration of VM's across hosts when LUN is near full capacity.

Suppose I configure that if a LUN is near 85% of capacity , can i do a configuration that VM will be moved to another host without any manual intervention.

Thanks
