You can request the power status of all nodes by omitting the nodelist parameter. This returns all the
nodes whose status is either ON or OFF:
# shownode status

n2 ON
n1 ON
3.6 Locating a Given Node
Most nodes supported on the HP XC system have a Unit Identifier LED that can be lit; not all nodes have
this feature.
Follow this procedure to light the Unit Identifier LED on a node with this feature, given its nodename:
1. Log in as superuser.
2. Illuminate the LED on the specified node with the locatenode command:
# locatenode --on nodename
The Unit Identifier LED on the node illuminates on the node's front panel.
3. Invoke the locatenode command again, this time with the --off option to turn off the Unit Identifier
LED when you are done.
3.7 Disabling and Enabling a Node
You can disable one or more nodes in the HP XC system. Disabled nodes are ignored when the HP XC
system is started or stopped with the startsys and stopsys commands, respectively.
The setnode --disable command updates the CMDB to indicate a specified node or a group of nodes
as disabled. In the following example, nodes n2 and n3 are disabled:
# setnode --disable n[2-3]
The shownode disabled command indicates which nodes are currently disabled:
# shownode disabled
n2
n3
The setnode --enable command updates the CMDB to enable a specified node or a group of nodes.
In the following example, nodes n2 and n3 are enabled:
# setnode --enable n[2-3]
The shownode enabled command indicates which nodes are currently enabled.
# shownode enabled
n1
n2
n3
For more information, see setnode(8).
