Determining a Node's Power Status

You can determine a node's power status by using the shownode status command and specifying the node by its node name:

# shownode status n2
ON

Valid power states are ON, OFF, or FAILED.

Specifying more than one node lists the node name and the status, as shown here:

# shownode status n1 n2
n2        ON
n1        ON

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
