    7 When you issue the saveNode command as follows:
     7Nodehandler '''save''' command is used for capturing the current image of the node into an archive file on the image server. The set of command line options for imaging function are given by "orbit help save":

    13 the nodehandler will request the node specified to reboot itself and load orbit-PXE into RAM (see [wiki:Documentation/orbit-pxe/loading Orbit-PXE Loading]).  Once the node checks in with the Orbit-PXE's nodeagent the nodehandler will ask the node's nodeagent to save the current image it has loaded on disk by issuing the following command (TCP port 9006):
     27Imaging process starts by the request from the nodehandler to the PXE grid service to set the tftp server to [wiki:Internal/Infrastructure/PXEService provide the PXE image] for the node's IP address. The nodehandler will then request the specified node to reboot itself (trough CMC Grid Service request) and thus load that PXE image into RAM (see [wiki:Internal/Infrastructure/PXEImage]).  Once the node checks in with the PXE's nodeagent, the nodehandler will ask the node's nodeagent to save the current image it has loaded on disk by issuing the following command (TCP port 9006):

     39Once nodeagent is done the node will be turned off by the nodehandler trough the CMC service.
