How to Replace an Energy Storage Module (ESM) in an Oracle FS1-2 Controller

Solution

DISPATCH INSTRUCTIONS

- WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED:

Product knowledge, FS1-2 Flash Storage System

TIME ESTIMATE: 45 minutes

TASK COMPLEXITY: 1

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW:

What: An ESM in an FS1-2 Controller has failed and needs to be replaced. 

Where: There will be a System Alert that identifies the problem Controller.  Since the Controller will not boot with a failed ESM, it is almost certain that the System Alert will say that there is a Controller failure.

Why: An FS1-2 Controller ESM has failed.

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

The Controller with the ESM failure will have a warning status.  The other Controller must have a normal status as this procedure requires a Controller failover. 

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. Prepare the FS1-2 System for Service Procedure.
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 as pillar to access Guided Maintenance:
   1. Select System tab
   2. In the navigation tree, select Controllers.
   3. In the main window, right click on the Controller with the failed ESM and select View.
   4. In the pop-up View Controller window, select the failed Controller ESM 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 ESM failure causes the Controller itself to fail boot, Guided Maintenance will not be available for the ESM replacement.  Proceed to Step 2.
       
      
      NOTE - since it may not be possible to identify the location of the failed ESM from the GUI, use the markings on the front of the Controller, behind the air filter, to confirm the location.
       
2. Remove the failed ESM
1. Confirm Controller with the failed ESM is offline:
   
   • Controller Unit ID should be blank.
   • SP LED in front, below power button, should be on solid and green.
   • OK LED in front, above power button, should be slow blink (every 3 seconds or so) and green.
     
     
2. Obtain ILOM version to determine if power cords need to be removed:
   
   1. ssh to active Pilot
   2. ssh to surviving Controller
   3. ssh to problem Controller's ILOM and run version command:
   4. If ILOM version is 3.2.9.21 r117708 or higher, proceed to step 2-c.
   5. If ILOM version is lower, power must be removed from the problem Controller:
      1. Deploy the anti-tip legs and pull the Controller into the service position.
      2. Remove both power cords from the Controller.
3. Pinch the two green plastic tabs on the front of the Controller towards the middle and lower the air filter door.
4. Press the drive release button on the left side of the ESM and pivot the release lever to the right to disengage the ESM from the backplane.
5. Wait at least 60 seconds to be sure the ESM has discharged.
6. Pull the ESM clear from the Controller.
   
   
3. Install the replacement ESM.
   
   1. Insert the replacement ESM into the same slot as the failed ESM by pushing on the release button until the release arm catches and starts to move to the left.
   2. Pivot the release lever all the way to the left until the ESM locks into place.
   3. Close the air filter door.
   4. If the power cords were removed, reconnect them and return the anti-tip legs to their stored position.
      
      NOTE - because the Controller must cold start, it may take as long as 20 minutes for the boot process to complete (30 if ILOM has to sync) and the Controller to return to a normal status.
4. Once the Controller has completed booting, 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 ESM was successful - the System Alert associated with it should be gone and the FS1-2 should be normal/green.
