Loading an image

  1. Before we begin using the nodes, it's a good idea to check their status first. This is done with the omf stat command.
console> omf stat -t all

The node can be in 1 of 3 states

POWEROFF Node is available for use but turned off
POWERON Node is available and is on
NOT REGISTERED Node is not available for use
  1. It is recommended that the node be in the POWEROFF state prior to any experiment process. If the node is in the POWERON state you can use the omf tell command to get the node into the off state.
console> omf tell -a offh -t sdr2-lg1.sb1.cosmos-lab.org

  1. Use the omf stat to verify the node is in the POWEROFF state. At this point load an image with omf load command.

Once the node finishes the imaging process, the node is in the POWEROFF state. So use the omf tell command to turn it back on, give it some time to boot and then ssh into it.
