License PowerPath VE & vApp

Hi,

I am trying to license PowerPath 5.8 using a Served .lic file and the PowerPath vapp in an ESXi 5.1 environment.

I have copied the .lic file to /etc/emc/licenses on the vapp and can list the hosts from the vapp.

The hosts are showing as "license not installed" when I issue rpowermt host= version

When I attempt to register them I get "unable to connect to license server"

How can I specify the license server?
