Replacing an operational E2700 controller

You might need to replace an operational E2700 controller if it is not functioning optimally. For example, you might need to replace an operational controller that repeatedly hangs and needs to be rebooted or one that does not always reboot successfully.

About this task

If both controllers are functioning sufficiently to allow for a controlled shutdown, you can shut down the E5600SG controller to interrupt the connectivity to the E2700 controller.

Steps

  1. Put on antistatic protection.
  2. Label each cable attached to the E2700 controller, so you can reconnect the cables correctly.
  3. If the StorageGRID Webscale appliance is running in a StorageGRID Webscale system, shut down the E5600SG controller.
    1. From the service laptop, log in to the grid node:
      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. Stop all StorageGRID Webscale services:/etc/init.d/servermanager stop
    3. Shut down the E5600SG controller:shutdown -h now

      Shutting down the E5600SG controller interrupts the connectivity to the E2700 controller, so you can replace it.

  4. Turn off power to the enclosure, which turns power off to both controllers.
  5. Wait until all LED and seven-segment display activity on the rear of the controller has stopped.
  6. Remove the cables.
  7. Remove the controller, as described in the E2700 controller documentation.
  8. Insert the new controller, as described in the E2700 controller documentation.
  9. Replace all cables.
  10. Turn the power on to the controller.
  11. Monitor the seven-segment codes.
    • E2700 controller:

      The final LED state is 99.

    • E5600SG controller:

      The final LED state is HA for version 1.5 or later, or SG for version 1.3.
