| | 3 | 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. This will typically produce a result like: |
| | 4 | {{{ |
| | 5 | user@console.sb7:~$ omf stat |

| | 32 | Individual nodes are identified by their fully qualified domain name (FQDN). This establishes their "coordinates" and the "domain" to which they belong. Nodes in |
| | 33 | different domains can NOT see each other. |
| | 34 | |
| | 35 | 2. Node can be in 1 of 3 states: |
| | 36 | |
| | 37 | || POWEROFF || Node is Available for use but turned off || |
| | 38 | || POWERON || Node is Available and is on || |
| | 39 | || NOT REGISTERED || Node is not Available for use || |
| | 40 | |
| | 41 | 3. 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 |
| | 42 | to get the node into the off state. |
| | 43 | {{{ |
| | 44 | username@console.domain:~$ omf tell -a offh -t TOPOLOGY |
| | 45 | }}} |
| | 46 | The ''TOPOLOGY'' can take on many forms, the simplest being a comma separated list of FQDN's. There are special predefined topologies like: all, system:topo:circle, ... |
| | 47 | For more details see [wiki:/Software/cOMF OMF documentation] |
| | 48 | If the node is in the NOT REGISTERED state, you may need to wait for it to recover the POWEROFF state (it some times requires a few moments for the services to sync up). If |
| | 49 | the node never comes out of the NODE NOT AVAILABLE state please contact an administrator. |
| | 50 | |
| | 51 | 4. Prior to the experiment, users need to install an image on the hard disks of the nodes. If you have not created a custom image use the default starting image: |
| | 52 | '''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 |
| | 53 | the Orbit services / hardware. Loading an image is done with the [wiki:/Software/cOMF#load omf load command]. |
| | 54 | {{{ |
| | 55 | username@console.domain:~$ omf load -t TOPOLOGY -i IMAGENAME |
| | 56 | }}} |
| | 57 | Where ''TOPOLOGY'' is the set of nodes you wish to image , and !IMAGENAME is the name of the image you with to load. The most common sandbox starting image command |
| | 58 | would look like |
| | 59 | {{{ |
| | 60 | username@console.domain:~$ omf load -t all -i baseline.ndz |
| | 61 | }}} |
| | 62 | which will load all the nodes of sandbox 1 (totaling 1) with the [wiki:Documentation/SupportedImages baseline] image. An example run on sandbox 7 looks like: |
| | 63 | {{{ |
| | 64 | user@console.sb7:~$ omf load -t all -i baseline.ndz |
