Shut down the SG6000-CN controller to perform hardware maintenance.

What you'll need

You have physically located the SG6000-CN controller requiring maintenance in the data center. See Locate controller in data center.

About this task

To prevent service interruptions, confirm that all other Storage Nodes are connected to the grid before shutting down the controller or shut down the controller during a scheduled maintenance window when periods of service disruption are acceptable. See the information about monitoring node connection states.

Important If you have ever used an ILM rule that creates only one copy of an object, you must shut down the controller during a scheduled maintenance window. Otherwise, you might temporarily lose access to those objects during this procedure. See Manage objects with information lifecycle management.
Steps

  1. Shut down the SG6000-CN controller:

    Caution You must perform a controlled shut down of the controller by entering the commands specified below. It is a best practice to perform a controlled shutdown when possible to avoid unnecessary alerts, ensure full logs are available, and avoid service disruptions.

    1. If you have not already logged into the grid node, log in using PuTTY or another ssh client:

      1. Enter the following command: ssh admin@grid_node_IP

      2. Enter the password listed in the Passwords.txt file.

      3. Enter the following command to switch to root: su -

      4. Enter the password listed in the Passwords.txt file.

        When you are logged in as root, the prompt changes from $ to #.

    2. Shut down the SG6000-CN controller:

      shutdown -h now

      This command might take up to 10 minutes to complete.

  2. Use one of the following methods to verify that the SG6000-CN controller is powered off:

    • Look at the blue power LED on the front of the controller and confirm that it is off.

    • Look at the green LEDs on both power supplies in the rear of the controller and confirm that they blink at a regular rate (approximately one blink per second).
