Power Management - IBM Power Systems 775 Manual

nodestat: By default, nodestat completes the following steps:
1. Gets the sshd,pbs_mom, xend port status.
2. If none of the ports are open, nodestat gets the fping status.
3. For pingable nodes that are in the middle of deployment, nodestat gets the deployment
status.
4. For non-pingable nodes, nodestat shows 'noping'.
– <power_state>: When the sate is not on or running, reports back the output of rpower
<noderange> stat command.
Example 3-15 "nodestat" output example with power option and all nodes that are turned on
