Hi all,
I have a hardware problem on a old AlphaServer ES45 Model 2B, it presents a random reboot;
in operating panel display appaers 'FAN6 Failed FAN3 failed', same message at system's boot.
I have replaced both the fans, clean the errors but the messages are still present and reboot don't stop.
In SRM Console the output of 'show error' is only SMB0.CPU0 SYS_SERIAL_NUM Mismatch
and I have set it as a procedure.
Console Log report this messages:
CPU machine check/exception - CPU 1
Maintenance: diagnostic msg: Memory Troller:bad page
Maybe I have a memory's problem? What commands I could launch for deep diagnostic?
What log files? Have binary.errlog but it's hard to analyze it.
Thanks for tips and my apologies for my poor and bad english.
Giacomo B.
Solved! Go to Solution.

SolutionHello,
ES45 - Fan3 and Fan6 ocp message is displayed on power up
Fan3 and Fan6 ocp message is displayed on power up
Problem Description Fan3 and Fan6 ocp message is displayed on power up
Fan3 and Fan6 ocp message is displayed on power up
Fan4 and Fan5 ocp message is displayed on power up
Fan1 and Fan2 ocp message is displayed on power up
Changing the associated fan's does not fix the problem.
The pci backplane would be the likely cause, especially if both the failing fan's are monitored by one LM80 chip. The pci backplane has qty=3 LM80 chip's and each chip monitors qty=2 fan's.
LM80 chip #1 monitors fans 1+2
LM80 chip #2 monitors fans 4+5
LM80 chip #3 monitors fans 3+6
Please use below command to analyze the binary.errlog file
ana/err/elv trans binary.errlog
I work for HPE

Re: Hardware problem on AlphaServer ES45 Model 2B
Hi Kumaran,
after a month, yesterday I have replaced the PCI Backplane as suggested,
the problem is SOLVED! the AlphaServer is up&running without error.
Thank you very much for the precious and decisive indication
