How to clear fmadm log or FMA faults log

Host Power-On Failed: System Power OK, Open Boot not responding

I faced this issue while troubleshooting disk issue on Sun Fire V440.

The disk has intermittently undetected from host, tried to upgrade the OBP firmware from 4.13 to 4.30, found the amber light with below error messages:

"Host Power-On Failed: System Power OK, Open Boot not responding"

--------------
sc> poweron
SC Alert: Host System has Reset
sc>
SC Alert: Host Power-On Failed: System Power OK, Open Boot not responding
sc>
SC Alert: Host System has Reset
-------------

found related KB while searching on MOS:
"On V440/N440 2P systems with OBP 4.22.19 firmware and ALOM firmware 1.5.4 may encounter a host power on failure. (Doc ID 1000080.1)"
Root Cause
The root cause was determined to be the OBP probe timeout value of 2.5 seconds set in ALOM 1.5.4.
Deviation WO_35484 was issued to Celestica (CMX) to rework V440/N440 systems by loading ALOM 1.6.3 FW.

Document 1000080.1 can be found at: https://support.us.oracle.com/oip/faces/secure/km/DocumentDisplay.jspx?id=1000080.1

So, there is a bug on current ALOM. the OBP firmware is upgraded to the latest already, now what I need to do is to upgrade the ALOM firmware. Patch id/name is 10263984

Install patch ID  10263984, its contains 2 file. For V440, use "ALOM_1.6.10_fw_hw0.tar.gz".

Copy and extract file "ALOM_1.6.10_fw_hw0.tar.gz" to "/usr/platform/SUNW,Sun-Fire-V440/lib/images" directory.

Then, run command: "scadm download boot alombootfw"

bash-3.00# pwd
/usr/platform/SUNW,Sun-Fire-V440/lib/images
bash-3.00# gzcat ALOM_1.6.10_fw_hw0.tar.gz | tar xf -
bash-3.00# /usr/platform/`uname -i`/sbin/scadm download boot alombootfw
