+===== Rocks commands =====
+Rocks 5.0 includes a command line tool ''rocks'' to handle most system administration tasks.
-==== Re-install a node ====
+===== Boot-related commands =====
-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
+==== Reinstall a node ====
-# rocks list host boot | grep 0-6
+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.  To instruct a node to reinstall on the next boot:
-compute-0-6:  ------</code>
-Make sure to sync the config after you change the boot action.
-# 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.
+<code># rocks set host boot compute-0-6 action="install"
+# rocks set host installaction compute-0-6 action="install ilri"
+# rocks run host compute-0-6 'reboot'</code>
+==== Run memtest ====
+<code># rocks set host runaction compute-0-8 action="memtest"
+# rocks set host boot compute-0-8 action="os"
+# rocks run host compute-0-8 'reboot'</code>
+==== Monitor installation progress ====
+You can monitor a node's progress during the installation using VNC.  Make sure you're inside X on the head node, or logged in via SSH with X forwarding:
+<code>$ sudo rocks-console compute-0-8</code>
