ViPR 3.0 fewer ports assigned 0 than min_paths 2

Hi,

when I try to present a distirbuted crossconnected VPLEX Volume a failure occurs:

Error 12024: An exception has occurred assigning storage ports: Host 10.195.20.63 urn:storageos:Host:1de08289-e661-4ca2-9673-441083668134:vdc1 has fewer ports assigned 0 than min_paths 2; there may be too few initiators on this host to provide the requested number of paths

the Host is zoned and connected as well...

is there any idea outside to fix this failure?

regards Arne
