Adding Array Controllers - Upgrade from one 2x6 HA configuration to one 2x4 and one 2x2 HA configurations.


Note: These procedures assume that the first tray is at the bottom of the chassis.


  1. Have the customer backup all data and stop all I/O to the arrays.

  2. Before starting this service action enable the reserve cabinet(s) function.

    a) Reserve the cabinet(s) for maintenance.

    b) Enter a description of the service action (i.e. adding array controllers).

    c) Select the estimated amount of time of the service action from the pull-down.

    d) Select the Reserve Cabinet(s) button.

    e) Other users will be alerted that this service action is in progress when they log in.

    a) Select the Locate Array link from the pop-up screen.

    b) Select a contoller from the array that the controller card will be added to.

    c) Then select the "locate this array" link.

    d) Close the pop-up screen.

  5. The controller card blank is located in the middle of the tray when facing the rear of the tray.

    a) View the controller card blank location illustration.

  6. Remove the controller card blanks from the third, fifth and sixth trays.

    a) Loosen the Phillips retaining screw to unlock the latch handles.

    Note: The first tray should be on the bottom of the 2x6 configuration.

  7. Locate the trays with controllers, they should be the first and fourth of the 2x6 configuration.

  8. Remove the fiber-optic cable from the fourth tray controller card.

  9. Remove the Ethernet cable from the fourth tray controller card.

  10. Remove the controller card from the fourth tray.

  11. Insert the controller card in the available slot in the third tray.

    a) View the adding a controller card illustration.

  12. Push in the latch handles to secure the controller card with the connector.

  13. Tighten the retaining screw.

  14. Insert a new controller card in the available slot in the fifth tray.

  15. Push in the latch handles to secure the controller card with the connector.

  16. Tighten the retaining screw.

  17. Insert a new controller card in the available slot in the sixth tray.

  18. Push in the latch handles to secure the controller card with the connector.

  19. Tighten the retaining screw.

  22. Insert the Ethernet cables into the Ethernet connectors where necessary.

  23. Check the controller LEDs to confirm that all of the controllers are operational. When the controller is operational, the LED is green.

    Note: During a controller boot process, if the Power-On-Self-Test detects a fatal problem with the controller, the system prevents the controller from going online. If this happens, the amber LED, which normally indicates a controller failure, will not light.

  24. Turn off the tray locator LED: Locate tray.

    a) Select the Locate Array link from the pop-up screen.
