Replace storage controller in the SG6000

You might need to replace an E2800 series controller or an EF570 controller if it is not functioning optimally or if it has failed.

Before you begin

  • You have a replacement controller with the same part number as the controller you are replacing.

  • You have labels to identify each cable that is connected to the controller.

  • You have an ESD wristband, or you have taken other antistatic precautions.

  • You have a #1 Phillips screwdriver.

  • You have physically located the storage appliance where you are replacing the controller in the data center.

Note
 Don’t rely on the E-Series instructions to replace a controller in the StorageGRID appliance, because the procedures aren’t the same.
About this task

You can determine if you have a failed controller in two ways:

  • The Recovery Guru in SANtricity System Manager directs you to replace the controller.

  • The amber Attention LED on the controller is on, indicating that the controller has a fault.

    Note
    		 If both controllers in the shelf have their Attention LEDs on, contact technical support for assistance.

If your appliance contains two storage controllers, you can replace one of the controllers while your appliance is powered on and performing read/write operations, as long as the following conditions are true:

  • The second controller in the shelf has Optimal status.

  • The OK to remove field in the Details area of the Recovery Guru in SANtricity System Manager displays Yes, indicating that it is safe to remove this component.

Note
 When possible, place the appliance into maintenance mode for this replacement procedure to minimize the potential impact of unforeseen errors or failures.
Note
 If the second controller in the shelf does not have Optimal status or if the Recovery Guru indicates that it is not OK to remove the controller, contact technical support.

When you replace a controller, you must remove the battery from the original controller and install it in the replacement controller. In some cases, you might also need to remove the host interface card from the original controller and install it in the replacement controller.

Note
 The storage controllers in most appliance models don’t include host interface cards (HIC).

Step 1: Prepare the replacement controller

Prepare the replacement E2800A or E2800B controller.

Steps

  1. Unpack the new controller, and set it on a flat, static-free surface.

    Save the packing materials to use when shipping the failed controller.

  2. Locate the MAC address and FRU part number labels on the back of the replacement controller.

Step 2: Take the controller offline

Prepare to remove the failed controller and and take it offline.

Steps

  1. Prepare to remove the controller. You use SANtricity System Manager to perform these steps.

    1. Confirm that the replacement part number for the failed controller is the same as the FRU part number for the replacement controller.

      When a controller has a fault and needs to be replaced, the replacement part number is displayed in the Details area of the Recovery Guru. If you need to find this number manually, you can look on the Base tab for the controller.

      Caution
      		 Possible loss of data access — If the two part numbers aren’t the same, don’t attempt this procedure.

    2. Back up the configuration database.

      If a problem occurs when you remove a controller, you can use the saved file to restore your configuration.

    3. 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 if the replacement does not resolve the problem.

    4. Take the controller you plan to replace offline.

  2. Power off the controller shelf.

Step 6: Replace controller

Install the replacement controller and verify that it has rejoined the grid.

Steps

  1. Install the replacement controller into the appliance.

    1. Turn the controller over, so that the removable cover faces down.

    2. With the cam handle in the open position, slide the controller all the way into the appliance.

    3. Move the cam handle to the left to lock the controller in place.

    4. Replace the cables and SFPs.

    5. Power on the controller shelf.

    6. If the original controller used DHCP for the IP address, locate the MAC address on the label on the back of the replacement controller. Ask your network administrator to associate the DNS/network and IP address for the controller you removed with the MAC address for the replacement controller.

      Note
      		 If the original controller did not use DHCP for the IP address, the new controller will adopt the IP address of the controller you removed.

  2. Bring the controller online using SANtricity System Manager:

    1. Select Hardware.

    2. If the graphic shows the drives, select Show back of shelf.

    3. Select the controller you want to place online.

    4. Select Place Online from the context menu, and confirm that you want to perform the operation.

    5. Verify that the seven-segment display shows a state of 99.

  3. Confirm that the new controller is Optimal, and collect support data.
