Remove and Replace a Tray Controller (Raid Controller and I/O Module)

$DEV_NAME $FRU_NAME, has been selected.

To prepare for this service action, perform the following:

- Enable the reserve the Common Storage Module (CSM) or Common Expansion Module (CEM) function.

  1. Reserve the CSM/CEM for maintenance.

  2. Enter a description of the service action (replacing a controller).

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

  4. Select the Reserve button.

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

- Generate a current FRU inventory.

- Observe all ESD precautions.

- Important Note: When replacing the I/O Module (IOM) steps 8 through 13 and 15 through 19 can be skipped since the IOM does not have a battery. Step 14 must still be followed

  To Remove and Replace a Tray Controller

  1. If needed, to help locate the correct tray, activate the flashing Amber LEDs:

     a) Turn on the tray disk drive Amber LEDs.

     b) View the the tray disk drive LED location illustration.

     Note: All off the disk drive Amber LEDs will flash.

  2. Remove the back cover if needed.

  3. From the rear, locate the failed controller by checking the fault lights. If a fault is detected, the Amber LED will be on.

     a) Controller card "A" is located on the left and controller card "B" is located on the right when viewing the CSM/CEM from the rear.

     b) View the controller card location illustration.

  4. Verify that the controller is ready to remove.

     a) The controller card status should be "failed".

     b) If the controller card is not "failed" call your Sun Service provider.

  5. From the failed controller disconnect the host and expansion interface cables including the SFP transceivers if this is a raid controller. Ensure that all cables are labeled before removing them.

  6. If the controller card is ready for removal, push down on the black spring loaded latch in the middle of the controller card that secures the two removal levers in place. While pushing down on the latch, pull the lever handles outward to remove the controller card from the CSM/CEM.

     a) View the controller card removal illustration.

  7. Unpack the new controller and save all of the packing materials to return the failed controller in. Use care when handling either the new or the failed controller.

  8. Prepare to remove the battery from the failed controller and install it in the new controller.

  9. Turn the failed controller over and place it on a flat surface so that the bottom is facing up.

  10. Remove the six Phillips screws, three per side, that secure the controller cover in place.

      a) View the screw removal illustration.

  11. Slide the cover back slightly and lift the cover carefully from the controller being careful with the battery cable that is still connected to the controller card.

      a) View the cover removal illustration.

  12. Disconnect the battery cable from the connector on the controller card.

  13. From the new controller remove the six Phillips screws, three per side, that secure the controller cover in place.

  14. Record the MAC address for the new controller from the white label on the controller cover before inserting it in the tray. This information will be needed in Step 27.

      a) View the MAC address label location.

  15. Slide the cover back slightly and lift the cover off.

  16. Take the controller cover with the battery and connect the battery cable to the connector on the new controller card and slide the controller cover back in place.

  17. Secure the controller cover in place with all six Phillips screws.

  18. Secure the other controller cover in place with all six Phillips screws on the failed controller and place it in an antistatic bag.

  19. Insert the new controller until it connects with the midplane connector. Use care not to bend any pins.

  20. Push in the latch handles to secure the new controller with the connector being sure that the latch holds the handles in place.

  21. Reconnect all host interface cables and drive interface cables, including the SFP transceivers, to their original locations.

  22. Wait approximately 60 seconds for the controller to complete it's boot process.

      a) All Link LEDs should be on.

      b) All Fault LEDs should be off.

      c) The battery charged (solid green) or charging (flashing green) LED should be on.

  23. If the battery from the failed controller was used, the age does not need to be reset. If a new battery was installed, the age must be reset.

      a) Reset the battery age.

      CAUTION: Potential data loss. If the battery age is not set correctly, you may not be notified to change the battery at the correct time, and data loss could occur. Contact your Sun Service provider if the battery age has been reset by mistake.

  24. Verify the controller "State" and "Status".

      a) The controller "State" should be "Enable" and the "Status" should be "OK".

  25. A new FRU inventory will need to be created for the new controller: Generate new FRU inventory.

  26. The revision level of the new controller must be checked to confirm compatibility: Validate revision level.

      a) From the Revision Checking screen, select the correct Host from the drop down box.

      b) Select the correct Matrix from the drop down box.

      c) Select the correct tray from the Module drop down box.

      d) If an email is required, enter the appropriate email address.

      e) Click on the "Run" tab.

  27. Change the BOOTP server configuration to the MAC address you recorded in step 14. Refer to your specific operating system administrators guide for detailed information on the configuration procedure.

  28. The volumes may need to be moved back to the original/preferred controller. Return to the Sun Web Console and use the Sun StorEdge 6130 Configuration Service to redistribute the volumes.

  29. Turn off the Amber LEDs used to locate the CSM/CEM.

      a) Turn Off tray LEDs.

  30. Disable the reserve CSM/CEM function.

      a) Select the Release button.
