Managing Faults 47
In the following example, POST reports a memory error at FB-DIMM location
/SYS/MB/CPU0/CMP0/BR1/CH0/D0. The error was detected by POST running on
core 7, strand 2.
EXAMPLE: show Command Output
Perform further investigation if needed.
■If POST detects a faulty device, the fault is displayed and the fault information is
passed to the service processor for fault handling. Faulty FRUs are identified in
fault messages using the FRU name.
■The fault is captured by the service processor, where the fault is logged, the
Service Required LED is lit, and the faulty component is disabled. See EXAMPLE:
Fault Detected by POST on page 54.
■Run the ILOM show faulty command to obtain additional fault information.
In this example, /SYS/MB/CPU0/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
“Disabling Faulty Components” on page55.
