    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:

    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.
     6 2. 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
     7    to get the node into the off state.
     8    [[Include(/Software/cOMF/eStatus)]]

    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, ...
    4710    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.
     11    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 takes more than 60 seconds to come out of the NODE NOT AVAILABLE state please report it to an administrator.

    5113 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:
    5214    '''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
