DISPATCH INSTRUCTIONS

- WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED:

Product knowledge, FS1-2 Flash Storage System

TIME ESTIMATE: 45 minutes

TASK COMPLEXITY: 2

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW:

What: A Controller NV-DIMM in an FS1-2 has failed and needs to be replaced.

Where: There will be a System Alert that identifies the NV-DIMM location. 

Why: An FS1-2 Controller NV-DIMM has failed.

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

The Controller with the NV-DIMM failure will have a warning status.  The other Controller must have a normal status as this procedure requires a Controller failover so that the problem Controller can be powered off in order to replace the failed NV-DIMM.

 QRC for this procedure:

To familiarize yourself with this procedure in general a video can also be found here.  But it should not be viewed as a substitute for the instructions below.

WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE:

1. Disable Call-Home to prevent spurious alerts (see <Document 1942676.1> FS System: How to Disable Call-Home to Prevent Automatic Service Request (ASR) Generation).
2. Use ESD precautions.
3. Log into Oracle FS System Manager to access Guided Maintenance:
1. Select System tab
2. In the navigation tree, expand Hardware and select Controllers
3. In the main window, double click on the Controller with the failed NV-DIMM.
4. In the pop-up Modify window, select the failed NV-DIMM and then click on Replace Component.
5. Follow the steps in Guided Maintenance to identify and place the Controller offline.
   
   
   NOTE - at this time, if the NV-DIMM failure causes the Controller itself to fail boot, Guided Maintenance will not be available for the NV-DIMM replacement.  Proceed directly to Step 4.
   
   
   
   NOTE - Since it may not be possible to identify the location of the failed NV-DIMM from the GUI, use the Service Label on the inside of the Controller top cover, to confirm the location.
    
4. Deploy the anti-tip legs in the front of the rack.
5. Slide the Controller into the service position.
6. Unplug both power cords.
7. Loosen the two captive screws in the rear of the Top Cover.
8. Slide the Top Cover back and remove.
9. Squeeze the two green tabs on the air filter in front and remove it to access Energy Storage Modules (ESMs).
10. Using the Service label on the Drive Compartment identify and remove the ESM associated with the failed NV-DIMM.
    
    NOTE - Exercise care when handling ESMs as they remain energized for several minutes after power is removed.
     
11. Unplug the cables connected to the Drive Compartment - They should be labeled to make reconnections easier.
12. Loosen the four captive screws that secure the Drive Compartment to the Controller chassis and lift it into the service position.
13. Remove the clear plastic Air Duct.
14. Use the Fault Remind button (located between the Power Supply and the first riser) to confirm the location of the failed NV-DIMM.
15. Press the release tabs on both ends of the NV-DIMM to remove it.
16. Install the replacement NV-DIMM by inserting it into the slot evenly until the release tabs lock it into place.
17. Reinstall the clear plastic Air Duct.
18. Lower the Drive Compartment and secure the four captive screws.
19. Reconnect the cabling to the Drive Compartment.
    
    NOTE - Cabling information can be found on the Service Label affixed to the Drive Compartment.
     
20. Close the Top Cover being certain to catch the mushroom tabs in the front to secure it.  Failure to do so will inhibit the Controller being slid back into the rack.
21. Tighten the two screws in the rear.
22. Reinstall the ESM and air filter removed in steps 9 and 10.
23. Plug in both power cords.
24. Return the Controller to the rack position.
25. Return the anti-tip legs to their normal position.
26. Log into the ILOM to confirm the fault has cleared.
    
    1.  Start Fault Management Shell:
       
       ->start /SP/faultmgmt/shell
       Are you sure you want to start /SP/faultmgmt/shell (y/n)? y
       
       faultmgmtsp>
        
    2. List the active faults:
       
       faultmgmtsp> fmadm faulty -a
        
    3. If the newly replaced component is still listed as a fault, it can be cleared by using the replaced option on the appropriate slot number:
       
       faultmgmtsp> fmadm faulty replaced DIMM_##
        
       
       NOTE: NVDIMM slots are 8-11, left to right when viewed from front of Controller. 
        
    4. Confirm fault is cleared:
       
       faultmgmtsp> fmadm faulty -a
       No faults found
       faultmgmtsp> exit
       
       
       
27. When finished, re-enable Call-Home.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

 Confirm that the replacement NV-DIMM was successful - the System Alert associated with it should be gone and the FS1-2 should be normal/green.

Note: because the Controller must cold start, it may take as long as 15 minutes for the boot process to complete and the Controller to return to a normal status.
