Shutting down a system using the CLI

You can use the command-line interface (CLI) to shut down a system.

To power off your system, complete the following steps.

  1. Determine which hosts have access to volumes on this system by running the lshostvdiskmap command.
  2. Stop input/output (I/O) to the system from each host listed in step 1.
    Note: Failure to stop host I/O can result in failed I/O operations being reported to your host operating systems.
  3. Shut down the system using this command:
    stopsystem 
  4. Wait for the power light-emitting diodes (LEDs) on all node canisters in all control enclosures to blink at 1 Hz, indicating that the shutdown operation has completed.
