POST error messages use the following syntax:
c : s
> ERROR: TEST =
failing-tes t
c : s
> H/W under test =
FRU
c : s
> Repair Instructions: Replace items in order listed by H/W under test above
c : s
> MSG =
test-error-message
c : s
> END_ERROR
In this syntax, c = the core number, s = the strand number.
Warning and informational messages use the following syntax:
INFO
or
WARNING
: message
In Example 1-3 , POST reports a memory error at FB-DIMM location
/SYS/MB/CMP0/BR1/
CH0/D0
. The error was detected by POST running on core 7, strand 2.
b.
Run the
showfaults
command to obtain additional fault information.
The fault is captured by ALOM CMT CLI, where the fault is logged, the Service Required
LED is lit, and the faulty component is disabled.
Refer to
Example 1-4 .
In this example,
/SYS/MB/CMP0/BR1/CH0/D0
is disabled. The system can boot using
memory that was not disabled until the faulty component is replaced.
Note -
You can use ASR commands to display and control disabled components. See “1.8
Managing Components With Automatic System Recovery Commands” on page 46 .
