 ===== rocks commands =====
-  * Instruct a node to rebuild itself on the next reboot by removing its boot action
+==== Re-install a node ====
-<code># rocks remove host boot compute-0-6</code>
+Nodes' BIOS should be set to boot from PXE (network) first and then the local hard drives.  The PXE server changes the PXE configs depending on what ''bootaction'' you've set for the node in the rocks database.  Therefore, to instruct a node to rebuild itself, remove its boot action:
+<code># rocks remove host boot compute-0-6
 # rocks list host boot | grep 0-6
-# rocks sync config</code>
+compute-0-6:  ------</code>
+Make sure to sync the config after you change the boot action.
+<code># rocks sync config</code>
+After a successful install the bootaction is set to "os", which configures the PXE server to instruct the node to use a local disk upon boot.
