DISPATCH INSTRUCTIONS

- WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED:

Product knowledge, Oracle MaxRep

TIME ESTIMATE: 60 minutes

TASK COMPLEXITY: 2

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW:

What: The disk backplane in a MaxRep3 Engine has failed and needs to be replaced.

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

Why: The disk backplane in a MaxRep3 Engine has failed.

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

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

QRC for this procedure:

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

1. Confirm Product Serial Number Containers (PSNCs) are currently synchronized.
1. Use ssh to ILOM of the MaxRep3 Engine.
2. Enter restricted session mode and run the showpsnc command.
   
   
   -> set SESSION mode=restricted

   to allow Services to perform diagnostic tasks.
   
   [(restricted_shell) ORACLESP-1312FMxxxx:~]# showpsnc
   Primary: fruid:///SYS/DBP
   Backup 1: fruid:///SYS/MB
   Backup 2: fruid:///SYS/PDB
   
   Element           | Primary           | Backup1           | Backup2
   ------------------+-------------------+-------------------+-------------------
   PPN                 70893370            70893370            70893370
   PSN                 1312FMxxxx          1312FMxxxx          1312FMxxxx  <=== Product Serial Numbers must match
   Product Name        Sun Netra X4270 M3  Sun Netra X4270 M3  Sun Netra X4270 M3

3. If all 3 PSNs match, exit twice to close the session and proceed to step 2.
4. If the motherboard (MB) and power distribution board (PDB) are the same but disk backplane (DBP0) is different, it is safe to proceed to step 2 since the disk backplane will be replaced.
5. If any other condition exists, STOP!! and re-engage Oracle Support for steps to correct before proceeding to replace the failed disk backplane.
   
   
2. 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.
   
   
3. Access the failed disk backplane.
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.
   
   
4. Remove the failed disk backplane.
1. Remove the front air filter by pressing the two green tabs towards the center and tilting back.
2. Unplug the SAS drives from their drive slots - suggest they be labeled to return to same slots later on.
3. Unplug the cables connected to the Drive Compartment - suggest they be labeled to make reconnections easier.
4. Loosen the 4 captive screws that secure the Drive Compartment and lift it toward you into the service position.
5. Unscrew the 5 screws that secure the disk backplane to the Drive Compartment and remove.
   
   
5. Install the replacement disk backplane.
1. Use the two guide pins on either end (right side pin also doubles as screw hole) to align the replacement disk backplane in place.
2. Use the 5 screws removed in step 4-e to secure the disk backplane into the Drive Compartment.
3. Lower the Drive Compartment from the service position and secure in place with the 4 captive screws.
4. Reconnect the cables that were unplugged in steps 4-c and 4-d.
5. Insert the SAS drives back into their drive slots.
6. Reattach the air filter.
7. Secure the top cover in place using the 2 captive screws in the rear.
   
   
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.
4. Once the MaxRep3 Engine ILOM has completed its reboot, repeat step 1 to verify that the PSN of the replacement disk backplane is synchronized to the other two quorum devices.
   
   
7. After 4-5 minutes, the MaxRep3 Engine should have completed its 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.
