     6 1. Q: '''Are the resource times for our schedule in EST or in our team's local time which is MST?''' [[BR]]

     9 1. Q: '''I would like to find out the procedure to access a specific domain when I have been assigned two domains which overlap in time.''' [[BR]]
    1010    A: All omf commands accept -t flag which specifies a set of resource (nodes). That set can be specified as either list of nodes or a path to file containing a resource set. So if you have multiple virtual domains reserved, '''system:topo:all''' would refer to all nodes contained in all domains. If you just want to work with a subset of nodes, you could simply list them on a command line. For example, if you have approved reservation for zDC01 and DCGNUR01 and wanted to say image only nodes in DCGNUR01 you would issue
    1111{{{
    1212    omf load -i darpahurdle1.ndz -t node1-1.grid.orbit-lab.org,node3-3.grid.orbit-lab.org

     14 1. Q: '''Given that they don't have USRP hardware, what is the purpose of zDCXX domains?''' [[BR]]
    1615    A: The zDCXX domains are general purpose only, and can't be used for USRP testing. However, they might be useful for other functions, such as working with images, debugging, working with omf (useful tool to get familiar with), etc.

    7775 1. Q: '''How can I save my image? We are having problem saving our image, can you please advise?'''[[BR]]
    7876    A: You have to use Fully Qualified Domain Name (FQDN) of the node as an argument i.e. if you have a reservation for DCGNUR14 and want to save image from node3-13 you have to issue a command:
