 How to remove and replace a DIMM in  M12-2/M12-2S CMUU / CMUL

Solution

 

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED?: M12 systems training

TIME ESTIMATE: 60 minutes
TASK COMPLEXITY: 3

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:
PROBLEM OVERVIEW:  Faulty DIMM

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

Having a good data backup is not a pre-requisite but is a wise precaution.

In a single server configuration the only way to replace a DIMM  is via "System/Stopped" method which entails all partitions be shut down / powered off with input power cords disconnected.

In a M12S block configuration, "Active/Cold" and "System Stopped" methods are available.

The customer should:

conduct an orderly software system shutdown, "System Stopped"  (M12-2, M12-2S) 

or

Offline the proper server, "Active/Cold" , (12-2S only)  See: http://support.oracle.com/rs?type=doc&id=2248501.1

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

An electromagnetic strap/map is required when working with internal hardware.

System Stopped maintenance
1. When you conduct cold or system-stopped maintenance, make sure that you set the mode switch of the operation panel to the Service mode before you start the maintenance.
2. Stop the entire system.
3. Execute the replacefru command to release the maintenance-target cabinet from the system.
4. Remove all power cords from the PSU backplane unit of the maintenance-target cabinet.

Active/cold maintenance

1.  Verify the customer has removed the server requiring Service from the building block configuration.
2. When you conduct active/cold or system-stopped maintenance, make sure that you set the mode switch of the operation panel to the Service mode before you start the maintenance.
3. Remove all power cords from the PSU backplane unit of the maintenance-target cabinet.

Remove 

1. Per task instructions verify the location of the failed DIMM and remove the proper CMUU/CMUL

CMUU   http://support.oracle.com/rs?type=doc&id=(2244415.1)

or

CMUL   http://support.oracle.com/rs?type=doc&id=(2241836.1)

2. Place the CMUU/CMUL on a static mat and review the memory map attached to the CMU. Locate the DIMM that has failed and it's physical position on the CMU.

3. Remove the failed DIMM by  the memory by pressing downwards on the levers on either side of the DIMM'. 
4. Reinsert the new DIMM  into the  CMU.  Verify the levers on the sides of the slots are in the open position and gently press down on the DIMM until it clicks.
5. follow the instructions provided in 2244415.1  CMUU or 2241836.1 CMUL to reinstall and reassemble the server.

6. Connect the power cord which will return the server to a "hot state"

 If this is "active cold" replacement follow the steps in 2248503.1 to reintroduce the server into the building block configuration.

If this is a system stopped maintenance:

7. Set autoboot to false:
Example: XSCF> setpparparam -p 0 -s bootscript "setenv auto-boot? false"

8. Execute the setpparmode(8) command to deactivate the Autoboot function of the guest domain.
Example: XSCF> setpparmode -p ppar_id -m guestboot=off

9. Start the system
Example: XSCF> poweron -a

10. Enable RAID volume to check the status.
Execute the probe-scsi-all command to confirm that the RAID volume is not in the list.
Select a device to display the volume information and check that it is not enabled.

Example: {0} ok select /pci@8000/pci@4/pci@0/pci@0/scsi@0
{0} ok show-volumes

11. Execute the activate-volume command to enable the RAID volume.
Example: {0} ok 0 activate-volume

12f. Execute the show-volumes command to check that the RAID volume is enabled
Example: {0} ok show-volumes

13. Switch the mode switches of the master cabinet and cabinets whose XSCFs are in the standby state to the Locked mode.
14. Execute the setdate command to set the XSCF clock if needed

OBTAIN CUSTOMER ACCEPTANCE
WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE?:
Have customer boot the system and confirm system state before leaving site.
