= A brief Guide to Node Testing =

The procedure is different for different generations of nodes. We'll break it up into two classes:
 * [#OldrabbitBasedCM Old rabbit Based CM]
 * [#NewLantronixBasedCM New Lantronix Based CM]

== Old rabbit Based CM == #OldrabbitBasedCM
 1. First locate the node4-11 Node ID box, it looks like [[BR]]
    [[Image(node_id_4-11.jpg, 20%)]]
 1. Wire the control, CM, monitor, and keyboard to their respective ports [[BR]]
    [[Image(wire_node.JPG, 35%)]]
 1. Connect Power, the led on the top of the box should start flashing
 1. Connect via ssh to console.outdoor.orbit-lab.org
 1. Run
    {{{
ssugrim@console.outdoor:~$ omf-5.2 stat
 INFO NodeHandler: init OMF Experiment Controller 5.2.408
-----------------------------------------------
 INFO Topology: Loading topology 'system:topo:all'.
 Testbed : outdoor.orbit-lab.org
 .
 .
 .
 Node n_4_10 - State: NODE NOT AVAILABLE
 Node n_4_11 - State: POWEROFF
 Node n_4_12 - State: NODE NOT AVAILABLE
-----------------------------------------------
   }}}
   Note the status of node 4-11. 
 1. In a seprate session telnet to cons4-11 3025
    {{{
ssugrim@console.outdoor:~$ telnet cons4-11 3025
Trying 10.1.224.59...
Connected to cons4-11.outdoor.orbit-lab.org.
Escape character is '^]'.
    }}}    
 1. Turn on the node and then watch the console session for the pxe message and quickly collect the mac address. It should look like:
    {{{
Yukon PXE v3.06  (20041109)

CLIENT MAC ADDR: 00 0F EA 02 87 F4
GUID: 30303046-4541-3032-3837-4634FFFFFFFF
DHCP.-
    }}}
 1. Once you have the mac, turn off the node with omf-5.2 tell offh ![4,11].
    {{{
ssugrim@console.outdoor:~$ omf-5.2 tell offh [4,11]

 INFO NodeHandler: init OMF Experiment Controller 5.2.408
---------------------------------------------------
 Testbed : outdoor.orbit-lab.org - Command: offHard
 Node n_4_11 - Ok
---------------------------------------------------
    }}} 
 1. ssh to dhcp1 and edit the /etc/dhcpd3/dhcpd.conf file. (You may need to bounce of internal4 to do this)
 1. Find the line for node 4-11, in the outdoor group, and replace the mac address with the one you 
    copied from the console. The original line may look like
    {{{
        host node4-1 {hardware ethernet 00:03:1d:08:19:23; fixed-address 10.40.4.1;}

        # Dummy node for TESTING. This node should be wired to the outdoor control vlan.
        host node4-11 {hardware ethernet 00:03:1d:0a:9f:23; fixed-address 10.40.4.11;}

        host node1-201 {hardware ethernet 00:0F:EA:7C:C3:D1; fixed-address node1-201.outdoor.orbit-lab.org;}
    }}}
 1. Restart the dhcp server:
    {{{
root@dhcp1:/etc/dhcp3# /etc/init.d/dhcp3-server restart
 * Stopping DHCP server dhcpd3                                                                                                                                                                          [ OK ]
 * Starting DHCP server dhcpd3
    }}}
 1. Now try to load an image with omf-5.2 load ![4,11] !ImageName and observe the console. If you see faulty behavior you want to capture, log the  telnet session.
    {{{
ssugrim@console.outdoor:~$ omf-5.2 load [4,11] inventory.ndz
Imaging nodes: '[4,11]' with image 'inventory.ndz'
(Domain:  default from hostname)
(Timeout:  800 sec.)
 INFO NodeHandler: init OMF Experiment Controller 5.2.408
    }}}
    You may also see error messages on the monitor attached to the node.
