-When you issue the saveNode command as follows:
+Nodehandler '''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":

+Save a disk image from a given node into an archive file

+Usage:

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):
+Imaging 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]).
