Saving node images with Orbit-PXE

When you issue the saveNode command as follows:

saveNode 1,2

the nodehandler will request the node specified to reboot itself and load orbit-PXE into RAM (see 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):

S 10.18.1.2 SAVEIMAGE frisbee:/export/orbit/image/tmp node-1-2-sb8-timestamp.ndz

The nodeagent running on the node will then create /mnt/, mount the remote NFS server image path onto /mnt and issue the following command:

imagezip /dev/hda /mnt/node-1-2-timestamp.ndz

Once nodeagent is done the node will be halted through:

shutdown -h now
