4.6.4 Verifying Successful Replacement of a Faulty
FB-DIMM
1. Access the ALOM CMT sc> prompt.
Refer to the Sun Integrated Lights Out Management 2.0 Supplement for the Sun Netra
T5220 Server for instructions.
2. Run the showfaults -v command to determine how to clear the fault.
The method you use to clear a fault depends on how the fault is identified by the
showfaults command.
Examples:
■ If the fault is a host-detected fault (displays a UUID), continue to Step 3. For
example:
■ If the fault was detected by POST and resulted in the FB-DIMM being disabled,
such as the following,
In most cases, the replacement of the faulty FB-DIMM(s) is detected when the
service processor is power cycled. In this case, the fault is automatically cleared
from the system. If the fauilt is still displayed by the showfaults command,
then run the enablecomponent command to enable the FB-DIMM and clear
the fault.
3. Perform the following steps to verify the repair:
