Product knowledge, Oracle MaxRep

TIME ESTIMATE: 50 minutes

TASK COMPLEXITY: 0

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW:

What: A riser in a MaxRep3 Engine has failed and needs to be replaced.  Risers are cards that plug into the motherboard and provide slots PCIe cards to be installed parallel to the motherboard.

Where: See "show /System/Open_Problems" output from ILOM. 

Why: A MaxRep3 Engine riser has failed.

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

The MaxRep3 Engine with the riser failure will have a warning status in the Oracle FS System Manager GUI.  This procedure requires that the MaxRep3 Engine be powered off.

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

QRC for this procedure:

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

1. Prepare the MaxRep3 Engine for Service Procedure.
1. Using the ILOM interface, confirm the failed part and location:
• Browser: point a browser at the ILOM IP address and select Open Problems in the navigation tree on the left.
• CLI: ssh to ILOM IP address and execute "show /System/Open_Problems"
2. 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).
3. Shutdown the MaxRep3 Engine (see <Document 2066803.1> MaxRep: How to Perform a Graceful Shutdown of the Oracle MaxRep3 Engine).
4. Use ESD precautions.
2. Access the failed riser.
1. Deploy the anti-tip legs in the front of the rack.
2. Slide the MaxRep3 Engine into the service position.
3. Unplug both power cords.
4. Loosen the two captive screws in the rear of the top cover.
5. Slide the top cover back and remove.
6. There are 3 risers in a MaxRep3 Engine:
1. Riser 1 is next to the power supplies and contains slots 1 and 4.
2. Riser 2 is in the middle and contains slots 2 and 5.
3. Riser 3 is on the left and contains slots 3 and 6. - Riser 3 is a different part number than 1 or 2.
7. Unplug any external cables connected to the PCIe Card(s) in the riser to be replaced - suggest they be labeled to make reconnections easier.
   
   
3. Remove the failed riser
1. Loosen the two captive screws that secure the riser to the motherboard and then lift the riser and PCIe Card(s) clear of the MaxRep3 Engine chassis.
2. If the failed riser is #3, push down on the green tab to release the PCIe Card retainer and rotate it 180 degrees to free it's PCIe Cards.
3. After noting which slot(s) in the failed riser the PCIe Card(s) were located in, remove them from the riser.  PCIe Card(s) must be returned to the same slot they came from.
   
   
4. Install the replacement riser.
1. Reconnect the PCIe Card(s) removed in step 3-c into the same slots as the replacement riser.
2. If riser #3 was replaced, lock the PCIe Card retainer back in place.
3. Install the riser back into the motherboard.
4. Secure the riser and PCIe Card(s) in place using the 2 captive screws.
   
   
5. Reassemble MaxRep3 Engine components.
1. Reconnect any external cables to the same PCIe Card(s) as they were removed from in step 2-g.
2. Close the top cover being certain to catch the mushroom tabs in the front to secure it. Failure to do so will inhibit the MaxRep3 Engine being slid back into the rack.
3. Tighten the two captive screws in the rear of the top cover.
   
   
6. Return MaxRep3 Engine to operation.
1. Plug in both power cords.
2. Return the MaxRep3 Engine to the rack position.
3. Return the anti-tip legs to their normal position.
   
   
7. After 4-5 minutes, the MaxRep3 Engine should have completed it's boot sequence - Access the User Interface and resync any Protection Plans that require it (see <Document 2066803.1> MaxRep: How to Perform a Graceful Shutdown of the Oracle MaxRep3 Engine).
8. 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 riser was successful - the Warning under Status Summary in the Oracle FS System Manager GUI associated with it and the Open Problem in the ILOM both should be gone.
