FIELD ENGINEER INSTRUCTIONS

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

The customer should conduct an orderly software and system shutdown.
System power off is required.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Ensure system is shut down

2. Follow instructions in chapter 4 (Sun Fire T1000 Server Service Manual) to prepare the system for service.

The chassis cover might be very difficult to remove. If you press too hard on the cover lock button, the front edge of the cover might warp and bind. Also, elastic gasket material on the sides of the chassis might prevent the cover from sliding freely.

To work around this, lightly hold down the cover lock button and push the cover slightly toward the front of the chassis (this assists the unlocking action), then slide the cover approximately one half inch (12 mm) toward the rear of the chassis. You can now lift the cover off the chassis.

3. Locate the DIMM that you want to remove.

4. Note the DIMM location so that you can install the replacement DIMM in the same socket.

5. Push down on the ejector levers on each side of the DIMM until the DIMM is released.

6. Grasp the top corners of the DIMM and remove it from the motherboard.

7. Place the DIMM on an antistatic mat.

8. Unpack the replacement DIMMs and place them on an antistatic mat.

9. Ensure that the socket ejector tabs are in the open position.

10. Line up the replacement DIMM with the connector.

11. Push the DIMM into the socket until the ejector tabs lock the DIMM in place.

12. Follow instructions in Chapter 6 (Sun Fire T1000 Server Service Manual) to finish up hardware servicing.

13. Gain access to the ALOM sc> prompt.

14. Set POST to min mode

sc> setsc diag_level min

15. Run the showfaults -v command to determine how to clear the fault.

If the fault is a host-detected fault (displays a UUID), continue to step 16.
For 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 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

16. Perform the following steps to verify the repair:

sc> setkeyswitch diag
sc> poweron
sc> console

Watch the POST output for possible fault messages.

Log in with root and run:

# fmadm faulty

If any DIMM fault is reported by POST and/or fmadm, report the issue to back end support for further diagnostics.

17. Obtain the ALOM CMT sc> prompt, and run:

sc> setkeyswitch normal

18. 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.

19. Run the clearfault command.

sc> clearfault f92e9fbe-735e-c218-cf87-9e1720a28004

20. Switch to the system console.

sc> console

21. Issue the fmadm repair command with the UUID.

Use the same UUID that you used with the clearfault command.

# fmadm repair f92e9fbe-735e-c218-cf87-9e1720a28004

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE FE/CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Boot and test functionality of system, verify no service LEDs or error messages.
1. Run the Solaris "fmadm faulty" and/or SP/ILOM "show faulty" command (run "showfaults -v" command if only ALOM is supported ) 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
