Clear PSH-Detected Faults

When the PSH detects faults, the faults are logged and displayed on the console. In most cases, after the fault is repaired, the server detects the corrected state and automatically repairs the fault. However, you should verify this repair. In cases where the fault condition is not automatically cleared, you must clear the fault manually.

1. After replacing a faulty FRU, power on the server.
2. At the host prompt, determine whether the replaced FRU still shows a faulty state.

   # fmadm faulty

                     faulty
    
   Description : The number of correctable errors associated with this strand has
                 exceeded acceptable levels.
                 Refer to http://sun.com/msg/SUN4V-8002-6E for more information.
    
   Response    : The fault manager will attempt to remove the affected strand
                 from service.
    
   Impact      : System performance might be affected.
    
   Action      : Schedule a repair procedure to replace the affected resource, the
                 identity of which can be determined using 'fmadm faulty'.

   • If no fault is reported, you do not need to do anything else. Do not perform the subsequent steps.

   • If a fault is reported, continue to Step 3.

3. Clear the fault from all persistent fault records.

   In some cases, even though the fault is cleared, some persistent fault information remains and results in erroneous fault messages at boot time. To ensure that these messages are not displayed, type this Oracle Solaris command:

   # fmadm repair UUID

   For the UUID in the example shown in Step 2, type this command:

   # fmadm repair 21a8b59e-89ff-692a-c4bc-f4c5cccc

4. Use the clear_fault_action property of the FRU to clear the fault.

   -> set /SYS/PM0 clear_fault_action=True
   Are you sure you want to clear /SYS/PM0 (y/n)? y
   set 'clear_fault_action' to 'true
