286 IBM Power Systems 775 for AIX and Linux HPC SolutionThe command that is shown in Example 5-29 verifies that the compute nodes are shutdown.Example 5-29 Verifying the compute nodes are downrpower compute stateOther utility nodesIn this step, any utility nodes (login, backup, and so on) are shutdown, as shownExample 5-30.Example 5-30 Shutting down the utility nodesxdsh login -v shutdown -h nowThe command that is shown in Example 5-31 verifies that the utility nodes are stopped.Example 5-31 Utility nodes stoppedrpower login stateShutting down the storage nodesLoadLeveler, GPFS, and the compute nodes are down. This means that all dependencies onthe storage nodes are stopped and the storage nodes are shut down, as shown inExample 5-32.Example 5-32 Shutting down the storage nodesxdsh storage -v shutdown -h nowThe command that is shown in Example 5-33 verifies that the storage nodes are shut down.Example 5-33 Verifying the storage nodes are downrpower storage stateShutting down the service nodesWith the compute and storage nodes down, there are no other dependencies on the servicenodes and the service nodes are shut down, as shown in Example 5-34.Example 5-34 Shutting down the service nodesxdsh service -v shutdown -h nowThe command that is shown in Example 5-35 verifies that the service nodes are shut down.Example 5-35 Verifies that the service nodes are downrpower service statePowering off the CECsThis section describes the process for shutting down the CECs.After the compute, utility nodes (if any), storage, and service nodes are shut down, the CECsare powered off, as shown in Example 5-36 on page 287.
