| 16 | | Prior to executing the "Hello World" experiment, users need to install an image on the hard disks of the nodes. For this tutorial we will use '''baseline.ndz'''. This image is built on top of '''Ubuntu 12.04''', and is pre-configured with the proper modules and start up scripts to take advantage of the rest of the Orbit [wiki:/Software software] / [wiki:/Hardware hardware]. The imaging process will turn the nodes back off after completing imaging. |

| 18 | | At this point the nodes disks are imaged with the ''baseline'' image and need to be turned back on before proceeding. Give the nodes a couple of minutes to turn on / boot, then check their status with omf stat |
