How to replace an Oracle ZFS Storage ZS5-2 DIMM

Solution

CAP PROBLEM OVERVIEW: Oracle ZFS Storage ZS5-2 Memory DIMM replacement

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:
Oracle ZFS Storage ZS5-2 Training.

TIME ESTIMATE: 30 minutes

TASK COMPLEXITY: 0

FIELD ENGINEER INSTRUCTIONS

WHAT STATE SHOULD THE APPLIANCE BE IN READY TO PERFORM THE RESOLUTION ACTIVITY? :

If the system is still up and functioning, customer should perform an orderly and graceful shutdown of applications and OS.  A data backup is not a prerequisite but is a wise precaution.

Removing the motherboard is a cold-service operation. You must power off the appliance and remove the DIMM.

There will be a loss of access to the storage unless the system is in a clustered configuration.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Identify the faulted DIMM.
   
   • Go to the Maintenance > Hardware section of the BUI, click the right-arrow icon for the controller, click DIMM, and note the ID of the faulted DIMM, which has an amber icon.
   
   • To highlight the location of the memory module in the controller picture, click on the module ID. To view details about the faulted module, click its information icon and then click Active Problems.
   
   
2. Shutdown the controller using one of the power-off methods.
   
   • Log in to the BUI and click the power icon on the left side under the masthead.
   
   • SSH in to the appliance and enter the maintenance system poweroff command.
   
   • Use a pen or non-conducting pointed object to press and release the Power button on the front panel.
   
   
   
3. Disconnect the AC power cords from the rear panel of the storage controller.
   
   
   
4. Disconnect all cables from the back of the storage controller. Squeeze the slide release latches, slowly pull the storage controller forward until the slide rails latch.
   
   
   
5. Fully loosen the two captive screws at the rear of the top cover and remove the top cover.
   
   
   
6. Press the Fault Remind button on the motherboard to illuminate the DIMM fault LED.
   
   
   
7. Disconnect the cables attached to the drive backplane, and the cable attached to the USB board carefully.
   
   
   
8. Fully loosen the four screws securing the drive cage to the chassis and rotate the drive cage to the vertical position.
   
   
   
9. Fully loosen the thumbscrew on the left bracket and lift the air duct straight up and off the alignment pins.
   
   
   
10. To remove the faulted DIMM, press down and out on the release levers at both ends of the DIMM slot.
    
    
    Note: The Oracle ZFS Storage ZS5-2 controller supports only fully populated DIMM's, 16 GB for 384 GB or 32 GB for 768 GB. Do not mix DIMM capacities; use either all 16 GB or 32 GB DIMMs.
      
    
    
11. Install each of the replacement DIMMs in the corresponding DIMM sockets on the MB, pressing firmly so that both release levers click closed.
    
    
    
12. Install the air duct to where it installs into the chassis and align the pins.
    
    
    
13. Lower the drive cage to the horizontal position. Tighten the four screws securing the drive cage to the chassis.
    
    
    
14. Connect the cables to the drive backplane, and the cable attached to the USB board. Plug each cable into its connector until you hear an audible click.
    
    
    
15. Install the top cover on the chassis, and tighten the two captive screws at the back of the top cover and slowly push the storage controller backward until the slide rails back to its original position.
    
    
    
16. Reconnect the power cords to the power supplies.
    
    
    
17. Verify that standby power is on. Approximately two minutes after plugging in the power cords, the Power/OK status indicator on the front panel flashes.
    
    
    
18. Check the ILOM to ensure that the fault has been cleared automatically and if not clear it manually. If the fault has not been cleared automatically, and you have to clear it manually, please make note that you must also reset the server again so the previously mapped out DIMM will be brought online.
    
    
    
    1. Login to the ILOM CLI and launch a Fault Management Shell session 
       -> start /SP/faultmgmt/shell
       Are you sure you want to start /SP/faultmgmt/shell (y/n)? y
       
       faultmgmtsp>
        
    2. Use the "fmadm faulty -a" command to list out all active faulty components
       faultmgmtsp> fmadm faulty -a
        
    3. If the DIMM that was just replaced is still listed as a fault then indicate that the DIMM has been replaced by using the command "fmadm replaced <fru|cru|uuid>" for example: 
       faultmgmtsp> fmadm replaced /SYS/MB/P0/D2
        
    4. Confirm that the faults are cleared and then exit out of the fault management shell
       faultmgmtsp> fmadm faulty -a
       No faults found
       faultmgmtsp> exit
       ->
    
    
    
19. Press and release the recessed Power button on the storage controller front panel.
    
    
    
20. The Power/OK status indicator next to the Power button lights and remains lit.
    
    

• Go to the Maintenance -> Hardware screen of the BUI. Click the right-arrow icon for the controller, click DIMM, and verify that the status icon image: is green for the newly installed module. To view details about the new module, click its information icon.
  
  
• If a fault does not self-clear, Repair the Active Problems from Maintenance -> Problem -> select Problem-xxx -> Mark Repaired -> Y
