|
Note - Not all DIMMs detected as faulty and offlined by POST must be replaced. In service (maximum) mode, POST detects memory devices with errors that might be corrected with Solaris PSH. See Section 3.4.5, Correctable Errors Detected by POST. |
|
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, follow the antistatic practices as described in Chapter 4. |
1. Perform the procedures described in Chapter 4.
2. Locate the DIMM that you want to remove.
Use FIGURE 5-11 and TABLE 5-1 to identify the DIMM that you want to remove.
TABLE 5-1 maps the DIMM names that are displayed in faults to the socket numbers that identify the location of the DIMM on the motherboard. The Channel/Rank/DIMM locations (for example, CH0/R0/D0) are silkscreened on the board and on a label near the board.
3. Note the DIMM location so that you can install the replacement DIMM in the same socket.
4. Push down on the ejector levers on each side of the DIMM until the DIMM is released.
5. Grasp the top corners of the DIMM and remove it from the motherboard.
6. Place the DIMM on an antistatic mat.
Use the following guidelines and FIGURE 5-11 and TABLE 5-1 to plan the memory configuration of your server.
1. Unpack the replacement DIMMs and place them on an antistatic mat.
2. Ensure that the socket ejector tabs are in the open position.
3. Line up the replacement DIMM with the connector.
4. Push the DIMM into the socket until the ejector tabs lock the DIMM in place.
5. Perform the procedures described in Chapter 6.
|
Note - You must replace the top cover as instructed in the Chapter 6 chapter before proceeding with these instructions. The top cover must be in place for ALOM CMT to detect that a DIMM has been replaced. |
6. Gain access to the ALOM sc> prompt.
Refer to the Advanced Lights Out Management (ALOM) CMT Guide for instructions.
7. Run the showfaults -v command to determine how to clear the fault.
The method you use to clear a fault depends on how the fault is identified by the showfaults command.
then run the enablecomponent command to enable the FRU:
8. Perform the following steps to verify the repair:
a. Set the virtual keyswitch to diag so that POST will run in Service mode.
c. Switch to the system console to view the POST output.
Watch the POST output for possible fault messages. The following output is a sign that POST did not detect any faults:
d. Return the virtual keyswitch to normal mode.
e. Issue the Solaris OS fmadm faulty command.
No memory or DIMM faults should be displayed.
If faults are reported, refer to the diagnostics flow chart in FIGURE 3-1 for an approach to diagnose the fault.
9. Obtain the ALOM CMT sc> prompt.
10. Run the showfaults command.
If the fault was detected by the host and the fault information persists, the output will be similar to the following example:
sc> showfaults -v ID Time FRU Fault 0 SEP 09 11:09:26 MB/CMP0/CH0/R0/D0 Host detected fault MSGID: SUN4V-8000-DX UUID: f92e9fbe-735e-c218-cf87-9e1720a28004 |
If the showfaults command does not report a fault with a UUID, then you do not need to proceed with the following steps because the fault is cleared.
11. Run the clearfault command.
12. Switch to the system console.
13. Issue the fmadm repair command with the UUID.
Use the same UUID that you used with the clearfault command.
The motherboard and chassis are replaced as a unit. Therefore, you must remove all FRUs and associated cables from your chassis, and install them in the new chassis.
1. Perform the procedures described in Chapter 4.
2. Remove the PCI-Express card.
See Section 5.1, Replacing the Optional PCI-Express Card.
3. Remove the fan tray assembly and cable.

6. Remove all DIMMs from the motherboard assembly.
See Section 5.5, Replacing DIMMs.
7. Remove the socketed system configuration SEEPROM from the motherboard and place it on an antistatic mat.
The system configuration SEEPROM contains the persistent storage for the host ID and Ethernet MAC addresses of the system, as well as the ALOM configuration including the IP addresses and ALOM user accounts, if configured. This information will be lost unless the system configuration SEEPROM is removed and installed in the replacement motherboard. The PROM does not hold the fault data, and this data is no longer accessible once the motherboard and chassis assembly is replaced.
The location of this SEEPROM is shown in Appendix A.
