Chapter 3 Server Diagnostics 3-41
The following is an example of the ALOM CMT alert for the same PSH diagnosed
fault:
Note – The Service Required LED is also turns on for PSH diagnosed faults.
3.5.1.1 Using the fmdump Command to Identify Faults
The fmdump command displays the list of faults detected by the Solaris PSH facility
and identifies the faulty FRU for a particular EVENT_ID (UUID). Do not use
fmdump to verify a FRU replacement has cleared a fault because the output of
fmdump is the same after the FRU has been replaced. Use the fmadm faulty
command to verify the fault has cleared.
Note – Faults detected by the Solaris PSH facility are also reported through ALOM
CMT alerts. In addition to the PSH fmdump command, the ALOM CMT
showfaults command provides information about faults and displays fault UUIDs.
See Section 3.3.2, “Running the showfaults Command” on page 3-16.
1. Check the event log using the fmdump command with -v for verbose output:
In this example, a fault is displayed, indicating the following details:
■ Date and time of the fault (Sep 14 10:09)
■ Universal Unique Identifier (UUID) that is unique for every fault (f92e9fbe-
735e-c218-cf87-9e1720a28004)
■ The message identifier (SUN4V-8000-DX) that can be used to obtain additional
fault information
■ Faulted FRU (FRU: mem:///component=MB/CMP0/CH0:R0/D0/J0601), that in
this example MB is identified as the DIMM at
R0/D0 (J0601)
