Chapter 3 Server Diagnostics 3-35
b. Run the showfaults command to obtain additional fault information.
The fault is captured by ALOM, where the fault is logged, the Service Required
LED is lit, and the faulty component is disabled.
Example:
In this example,
MB/CMP0/CH0/R1/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 Section 3.7, “Managing Components With Automatic System Recovery
Commands” on page 3-45.
3.4.5 Correctable Errors Detected by POST
In maximum mode, POST detects and offlines memory devices with errors that
could be correctable by PSH. Use the examples in this section to verify if the
detected memory devices are correctable.
Note – For servers powered on in maximum mode without the intention of
validating a hardware upgrade or repair, examine all faults detected by POST to
verify if the errors can be corrected by Solaris PSH. See Section 3.5, “Using the
Solaris Predictive Self-Healing Feature” on page 3-39.
When using maximum mode, if no faults are detected, return POST to minimum
mode.
