Shutting down a system by using the CLI

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

Procedure

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 that is 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 by using this command: 
    stopsystem
  4. Wait for the power light-emitting diodes (LEDs) on all nodes or control enclosures to flash at 1 Hz, indicating that the shutdown operation has completed.
