Thank you for patience
I have confirmed with my Staff Engineer and he said that this error actually fake error. I have already informed to Kiatchumpol about this problem.
According to our staff engineer please ignore this issue, here is the reason
There is a BIOS memory selftest code, which will run each time system
startup. The BIOS program will inject an error code to check if the
MCE will report the error info and record in "mcelog". After finishing
the error inject test, the error info is not cleaned by BIOS program
when booting up finished. At this time, u could see the error info
above. If this happen, it's only a log record for test code and no
influence the system
will be changed/resolved in a future build/version of NetBackup appliance
(maybe an updated bios?).
Thank you in advance for your time and consideration.
Please let me know if you any query
