omf load

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

Usage: omf help load

Install a given disk image on the nodes in a testbed
      omf-5.4 load [-h] [-i IMAGE_PATH] [-o TIMEOUT] [-t TOPOLOGY] [-c AGGREGATE]
      -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. If the imaging process does not does not finish within the default timeout period, that period can be increase by using the -o flag (e.g. -o 1600). Typical command to load both nodes of sandbox 1 with the baseline? image would look like:

Example: omf load-i baseline.ndz -t system:topo:all

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