Solution 2100737.1 : How to replace an ODA memory dimm

Applies to:

Oracle Database Appliance - Version All Versions and later
Information in this document applies to any platform.

Goal

Provide basic steps for the replacement of a faulty memory module

Solution

Note: The DDR3 memory modules (DIMMs) are customer-replaceable units (CRUs) and do not require an Oracle-qualified service person for replacement

TASK COMPLEXITY: 0

TIME ESTIMATE: 20 minutes

For complete details of replacement procedures refer to the Oracle Database Appliance Service Manual http://docs.oracle.com/cd/E66274_01

Section 4. Servicing CRUS That require Server Node Power off.

You must shut down the server node before you remove it from the system chassis. Be sure that the customer has properly shutdown all applications and has properly failed over to the other node.

To shut down a server node you can use the power button or use ILOM .

Power button:

Graceful shutdown: Press and release the recessed Power button on the lower left-hand corner of the server node's front panel

This causes Advanced Configuration and Power Interface (ACPI) to perform an orderly shutdown of the system.

ILOM

To shut down a server node using the Oracle ILOM,

Using the Oracle ILOM web interface:
Open a browser and enter the server node's service processor IP address in the browser's address field.
At the log in page, type a user name (the account must have Reset and Host Control (r) privileges) and password, and click the Log In button.
Go to Remote Power Control

Select Graceful Shutdown and Power Off from the Select Action list box and then click Save and OK.

The server node shuts down gracefully.

1. Prepare the server node for service.

a. Attach an antistatic wrist strap. See the manual for attaching wrist strap and use of ESD mats and bags.

b. Remove the server node from the system.

To unseat the server node from the system chassis, pull the two latches on the rear of the server node down.

The latches are marked by green tabs. Pull the latches down and away from the rear to the system.

Slide the server node to the rear and lift it out of the system.

c. Remove the server node top cover.

To unlatch the server node top cover, press and hold the green release button on the top of the server node cover.

Using the indented area near the green release button, slide the cover toward the front of the server node about 0.5 inches (12.7 mm).

Lift the cover up and remove it.

2. Identify the faulty DIMM(s)

To identify the location of a faulty DIMMs, press the Fault Remind button on the motherboard. Refer to manual for locations and illustrations of the Fault Remind button and Dimm LEDs if required.

If the DIMM fault LED is off, the DIMM is operating properly.
If the DIMM fault Required LED is on (amber), the DIMM is faulty and should be replaced

3. To remove the faulty DIMM(s), do the following:

a. Rotate both DIMM slot ejectors outward as far as they go. The ejectors push the DIMM partially up.
b. Carefully lift the DIMM straight up to remove it from the socket.

4. Install the new DIMMS

a. Unpack the replacement DIMMs and place them on an antistatic mat.
Ensure that the replacement DIMMs match the system requirements.

The system supports only 1333 MHz or 1600 MHz DDR3, 8GB, dual rank DIMMs obtained from Oracle.

b. Ensure that the ejector tabs are in the open position.
c. Align the replacement DIMM with the connector.

d. Align the notch in the DIMM with the key in the connector. The notch ensures that the DIMM is oriented correctly.

e. Push the DIMM into the connector until the ejector tabs lock the DIMM in place.

f. Repeat Step 3 through Step 5 until all replacement DIMMs are installed.

5. Return the server node to operation.

a. Install the server node top cover.

b. Install the server node into the system.

c. Power on the server node.

6. Clear the DIMM faults.

a. Log in to the server node Oracle ILOM CLI as root.

b. To view server node faults, type the following command:

-> show /SP/faultmgmt

Oracle ILOM lists all known faults. For example:

           SP/faultmgmt
           Targets:
           0 (/SYS/MB/P0/D2)
                  Properties:
                Commands:
                cd
                show

c. To clear the DIMM fault, type the following command:

-> set /SYS/MB/Px/Dn clear_fault_action=true

For example, to clear a fault on the DIMM in location D2 on CPU0:

-> set /SYS/MB/P0/D2 clear_fault_action=true
Are you sure you want to clear /SYS/MB/P0 (y/n)? y
Set 'clear_fault_action' to 'true'
