Solution

DISPATCH INSTRUCTIONS

WHAT SKILLS ARE REQUIRED?: No special skills required, Customer Replaceable Unit (CRU) procedure

TIME ESTIMATE: 60 minutes

TASK COMPLEXITY: 0

REMOVAL/REPLACEMENT INSTRUCTIONS:

PROBLEM OVERVIEW:
Memory failure

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

A data backup is not a pre-requisite but is a wise precaution.
The customer should conduct an orderly software system shutdown.

Then power down the system and disconnect the Power Cord.

WHAT ACTIONS ARE REQUIRED?:

Note: The minimum configuration is one rank, Rank0 or Rank1. This requires configuring 8 identical DIMMs.

The DIMMs of Rank0 are independent of those in Rank1, and therefore can be of a different type.

Note – Not all DIMMs detected as faulty and offline by POST must be replaced. In service (maximum) mode, POST detects memory devices with errors that might be corrected with Solaris PSH.

Caution – This procedure requires that you handle components that are sensitive to static discharges that can cause the component to fail. To avoid this problem, ensure that you follow antistatic practices

Removing the DIMMs

1. Prepare the server for DIMM removal: Powering Off the Server, disconnecting Cables From the Server, Removing the Server From the Rack, Performing Antistatic Measures

2. Removing Top Cover

3. Remove the PCI Tray

4. Remove the DIMM/CPU duct.

5. Locate which DIMM is to be removed and press the ejector levers open, removing the DIMM

6. Set the DIMM aside on an antistatic mat.

7. Repeat from Step 5 for all DIMMs to be removed.

8. Consider your next step:
■ If you removed the DIMMs as part of another procedure, return to that procedure.
■ If you are to install DIMMs, continue to “Installing a DIMM”
■ If you are to only remove DIMMs:
a. Install the DIMM/CPU duct.
b. Perform the following tasks to bring the server back online:

9. Installing the PCI Tray, Installing the Top Cover, Removing Antistatic Measures, Reinstalling the Server Chassis in the Rack, Reconnecting Cables to the Server

10. Powering On the Server

Installing DIMMs

1. Remove the replacement DIMM from its packaging and place it on an antistatic mat.

2. Locate where the DIMM is to install and align it with the slot

3. Push the DIMM into the slot until the ejector levers close with a click

4. Repeat from Step 2 for all DIMMs to be installed.

5. Install the DIMM/CPU duct.

6. Perform the following tasks to bring the server back online: Installing the PCI Tray, Installing the Top Cover, Removing Antistatic Measures, Reinstalling the Server Chassis in the Rack, Reconnecting Cables to the Server

7. Powering On the Server

Perform the following steps to verify the repair:
1. Set the virtual keyswitch to diag so that POST will run in Service mode
2. Issue the poweron command.
3. Switch to the system console to view POST output.
4. Return the virtual keyswitch to normal mode.
5. Gain access to the ALOM CMT sc> prompt.
6. Run the showfaults -v command to determine how to clear the fault.

7. Run the clearfault command (for each UUID reported in 'showfaults')

The method you use to clear a fault depends on how the fault is identified by the showfaults command.

If the fault resulted in the FRU being disabled, such as the following,

sc> showfaults -v
ID Time FRU Fault
1 OCT 13 12:47:27 MB/CMP0/CH0/R0/D0 MB/CMP0/CH0/R0/D0
deemed faulty and disabled

Then run the enablecomponent command to enable the FRU:

sc> enablecomponent MB/CMP0/CH0/R0/D0

8. Switch to the system console.
Issue the fmadm repair command with the UUID. Use the same UUID that you used with the clearfault command.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTIONS ARE REQUIRED TO RETURN THE SYSTEM TO AN OPERATIONAL STATE?: 

Boot system and monitor boot sequence for errors. Test functionality of system:
1. Run the Solaris "fmadm faulty" and SP/ILOM "show faulty" command (if only ALOM is supported run "showfaults -v" command) to verify that the fault has been cleared.
2. Perform one of the following tasks based on your verification results:
   * If the previous steps did not clear the fault, refer to doc 1004229.1 for information about the tools and methods you can use to diagnose and clear component faults.
   * If the previous steps indicate that no faults have been detected, then the component has been replaced successfully. No further action is required
3. Restart software applications per applicable administration guides to resume system operation.
