| 30 | | To facilitate in imaging nodes, all nodes in every resource are preconfigured to netboot via the Intel Pre-Boot eXecution Environment. The ORBIT DHCP service instructs all nodes to download and execute Syslinux's pxelinux binary. The binary, upon execution, downloads a boot script via the Trivial File Transfer Protocol. When nodes are queued for imaging, the ORBIT PXE service creates links to a bootscript that forces the node to download and boot a small memory based linux distribution that launches the imaging client, frisbeed. After imaging, the ORBIT PXE service removes this link and, upon reboot, the nodes PXE boot but download a default boot script instructs the node to continue booting off of the hard disk. |

The ORBIT DHCP service instructs all nodes to download and execute Syslinux's pxelinux binary. The binary, upon execution, instructs the node to download and execute a boot script retrieved via the Trivial File Transfer Protocol. When nodes are queued for imaging, the ORBIT PXE service creates links on the TFTP server to a bootscript that forces the node to download and boot a small memory based linux distribution that launches the imaging client, frisbeed. After imaging, the ORBIT PXE service removes this link and, upon reboot, the nodes PXE boot as before, but download a default boot script which instructs the node to continue booting off of the hard disk. With this mechanism, the nodehandler simply instructs the ORBIT PXE server which nodes on any given resource to setup for imaging. |
