As Christoph and Jack suggested I have done the following: [[BR]]

1. Changed the name of the slice on the yaml file in the RC from just slicename to whole URN[[BR]]
2. POSTed the slice URN to the experiment service[[BR]]

The results are:[[BR]]
1. The RCs are unable to connect to the PubSub gateway on emmy9. If I do the same experiment from command line using omf exec the experiment runs[[BR]]
To test this I changed the slice names on 2/5 RCs and these 2 machines did not connect. The others showed as 'UP'. I changed the first 2 back to the slice names and was able to run omf exec experiments on them.[[BR]]
It seems like the nodes are unable to use URNs to connect to Labwiki.[[BR]]

2. The slice URNs are now being POSTed in the GIMI Experiment Service via the init script.
