    235235If you've modified the baseline, or even installed your own OS on a node, you can take a snapshot of the node's disk.  The resulting image can be used on other nodes during your experiment and reused during other slots.  To save a node's disk as an image issue the following command on the experiment console (**NOT THE NODE'S SERIAL CONSOLE**):
    236 {{{
    237    user@console.domain: omf save -n nodeX-Y.domain
    238 }}}
     236
     237 * user@console.domain: omf save -n nodeX-Y.domain
     238
    239239
    240240where X and Y are the node's coordinates.  The image will be named in the form username-node-fqdn-date.ndz and will be displayed in a status message during the save process.  Please keep track of the image name as you will need to supply it during imaging.

    242242ORBIT keeps your images on the machine named repository1 in the /export/omf/omf-images directory. They are considered temporary images unless you claim them by moving them to image repository with:
    243 {{{
    244 mv username-node-fqdn-date.ndz ../your-active-image-name.ndz
    245 }}}
     243
     244* mv username-node-fqdn-date.ndz ../your-active-image-name.ndz
     245
    246246
    247247Please bear in mind that the ORBIT software components (i.e. nodehandler/nodeagent, libmac, otr/otg, oml, and wireless drivers) are under constant development.  The baseline image is continually updated with the latest stable releases of these components.  If you are going to use your own derivative of the baseline and you use these components, may need to update these packages manually.  Please watch the orbit-user mail list for development related news.

    253253You can image the nodes you need with your image using the following command from the "console" machine
    254 {{{
    255    user@console.domain: omf load -t topology -i imagename.ndz
    256 }}}
     254
     255 * user@console.domain: omf load -t topology -i imagename.ndz
