Load an Image
- 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:
user@console.sb7:~$ omf stat
INFO NodeHandler: OMF Experiment Controller 5.4 (git c005675)
INFO NodeHandler: Slice ID: default_slice (default)
INFO NodeHandler: Experiment ID: default_slice-2013-01-16t15.28.15-05.00
INFO NodeHandler: Message authentication is disabled
INFO Experiment: load system:exp:stdlib
INFO property.resetDelay: resetDelay = 230 (Fixnum)
INFO property.resetTries: resetTries = 1 (Fixnum)
INFO Experiment: load system:exp:eventlib
INFO Experiment: load system:exp:stat
INFO Topology: Loading topology ''.
INFO property.nodes: nodes = "system:topo:all" (String)
INFO property.summary: summary = false (FalseClass)

Individual nodes are identified by their fully qualified domain name (FQDN). This establishes their "coordinates" and the "domain" to which they belong. Nodes in
different domains can NOT see each other.
- 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
|
- 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.
username@console.domain:~$ omf tell -a offh -t TOPOLOGY
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, …
For more details see OMF documentation
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
the node never comes out of the NODE NOT AVAILABLE state please contact an administrator.
- 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:
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 services / hardware. Loading an image is done with the omf load command.
username@console.domain:~$ omf load -t TOPOLOGY -i IMAGENAME
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
would look like
username@console.domain:~$ omf load -t all -i baseline.ndz
which will load all the nodes of sandbox 1 (totaling 1) with the baseline image. An example run on sandbox 7 looks like:
user@console.sb7:~$ omf load -t all -i baseline.ndz
