load

Load command is used to put an image onto the hard disk of the nodes.

omf help load

Install a given disk image on the nodes in a testbed
Usage:
      omf-5.4 load [-h] [-i IMAGE_PATH] [-o TIMEOUT] [-t TOPOLOGY] [-c AGGREGATE]
 
      With: 
      -h, --help                print this help message
      -c, --config AGGREGATE    use testbed AGGREGATE
      -t, --topology TOPOLOGY   a valid topology file or description (defaults to 'system:topo:all')
                                (if a file 'TOPOLOGY' doesn't exist, interpret it as a comma-separated list of nodes)
      -i, --image IMAGE         disk image to load
                                (default is 'baseline.ndz', the latest stable baseline image)
      -o, --timeout TIMEOUT     a duration (in sec.) after which imageNodes should stop waiting for
                                nodes that have not finished their image installation
                                (default is 800 sec, i.e. 13min 20sec)
          --outpath PATH        Path where the resulting Topologies should be saved
                                (default is '/tmp')
          --outprefix PREFIX    Prefix to use for naming the resulting Topologies
                                (default is your experiment ID)
 
      Some Examples: 
                    omf-5.4 load
                    omf-5.4 load -t system:topo:all -i baseline-2.4.ndz
                    omf-5.4 load -t omf.nicta.node1 -i wireless-2.6.ndz
                    omf-5.4 load -t omf.nicta.node1,omf.nicta.node2 -i baseline.ndz -o 400
                    omf-5.4 load -t system:topo:circle -i my_Own_Image.ndz
                    omf-5.4 load -t my_Own_Topology -i baseline-2.2.ndz -t 600 -c grid
                    omf-5.4 load -t my_Own_Topology --outpath ./ --outprefix my_Own_Prefix

Two important arguments are TOPOLOGY describing the set of nodes one wishes to image , and !IMAGE specifying the name of the image one wants to load the nodes with. Typical command to load both nodes of sandbox 1 with the baseline image would look like:

username@console.sb7:~$ omf load -t all -i baseline.ndz

username@console.sb7:~$ omf load -t all -i baseline.ndz
