Replacing the E2700 controller

You might need to replace the E2700 controller if it is not functioning optimally or it has failed.

Before you begin

About this task

You can determine if you have a failed controller by checking the amber Service Action Required LED on the controller (shown as 1 in the illustration). If this LED is on, the controller should be replaced.

The appliance Storage Node will not be accessible when you replace the controller. If the E2700 controller is functioning sufficiently, you can place the E5600SG controller into maintenance mode. Before changing the link configuration, you must place the E5700SG controller controller into maintenance mode. Putting a StorageGRID appliance into maintenance mode might make the appliance unavailable for remote access.

When you replace a controller, you must remove the battery from the original controller and install it in the replacement controller.

Procedure

  1. Prepare to remove the controller.
    You use SANtricity Storage Manager to perform these steps.
    1. Make a note of which version of SANtricity OS software is currently installed on the controller.
    2. Make a note of which version of NVSRAM is currently installed.
    3. If the Drive Security feature is enabled, be sure a saved key exists and that you know the pass phrase required to install it.
      Attention: Possible loss of data access – If all drives in the appliance are security enabled, the new controller will not be able to access the appliance until you unlock the secured drives using the Enterprise Management Window in SANtricity Storage Manager.
    4. Back up the configuration database.
      If a problem occurs when you remove a controller, you can use the saved file to restore your configuration.
    5. Collect support data for the appliance.
      Note: Collecting support data before and after replacing a component ensures you can send a full set of logs to technical support in case the replacement does not resolve the problem.
  2. If the StorageGRID appliance is running in a StorageGRID system, place the E5600SG controller into maintenance mode.
    1. From the Grid Manager, select Nodes.
    2. From the tree view of the Nodes page, select the appliance Storage Node.
    3. Select the Tasks tab.

    4. Click Maintenance Mode.
      A confirmation dialog box appears.

    5. Enter the provisioning passphrase, and click OK.
      A progress bar and a series of messages, including Request Sent, Stopping StorageGRID, and Rebooting indicate that the appliance is completing the steps for entering maintenance mode.

      When the appliance is in maintenance mode, a confirmation message lists the URLs you can use to access the StorageGRID Appliance Installer.

    6. Browse to any of the URLs displayed.
      Note: If possible, use the URL containing the IP address of the appliance's Admin Network port.
      Note: Accessing https://169.254.0.1:8443 requires a direct connection to the local management port.
    7. Confirm that the appliance is in maintenance mode by noting the maintenance mode message on the StorageGRID Appliance Installer home page.

  3. If the E2700 controller is functioning sufficiently to allow for a controlled shutdown, confirm that all operations have completed.
    1. From the title bar of the Array Management Window, select Monitor > Reports > Operations in Progress.
    2. Confirm that all operations have completed.
  4. Follow the instructions in the replacement procedure for a simplex E2700 controller to complete these steps:
    1. Label the cables and then disconnect the cables.
      Attention: To prevent degraded performance, do not twist, fold, pinch, or step on the cables.
    2. Remove the failed controller from the appliance.
    3. Remove the controller cover.
    4. Unscrew the thumbscrew and remove the battery from the failed controller.
    5. Install the battery in the replacement controller, and replace the controller cover.
    6. Install the replacement controller into the appliance.
    7. Replace the cables.
    8. Wait for the E2700 controller to reboot. Verify that the seven-segment display shows a state of 99.
  5. If the appliance uses secured drives, import the drive security key.
  6. Return the appliance to normal operating mode:
    1. From the StorageGRID Appliance Installer, select Advanced > Reboot Controller.

      reboot controller
    2. Click Reboot Controller.
      During the reboot, the following screen appears:
      Reboot in Progress

      The appliance reboots and rejoins the grid. This process can take up to 20 minutes.

    3. On the Nodes page, verify that the appliance node returns to the expected status by viewing the icon to the left of the node name.
      When the reboot is complete, the Tasks tab looks like the following screenshot:
      Reboot Complete
  7. From SANtricity Storage Manager, confirm that the new controller is Optimal, and collect support data.
