Isilon NL410 Node Backplane Light indicators (What do they mean?)
Hey Community,
Is there a doc that explains what the different light indicators mean on the backside of the Isilon NL410 nodes? Currently I have a flashing orange light on the back of one of my nodes and the rest have a solid green light. I run isi_hw_status and I don't see anything glaring at me as a possible hardware issue. Should I be looking for another command to show me what else could be wrong?
I have opened the installation guide for the NL410 and don't see anything in there telling me what the light indicators mean.
Thank you,
Yan Faubert,
Hey thank you for this info. I went ahead and reset the node to and started it back to the setup menu and the orange light went away. I am not saying this is the fix, but if that light start flashing again I will be sure to take a closer look at what you have here. Thank you for the quick response!

However it might not reveal much... See if you have any hardware events in the SEL (System Event Log), to list all SEL entries:
/usr/bin/isi_hwtools/isi_ipmicmc -S -V -p l
l is lowercase 'L'.
I had one such incident and it turned out to be the CMOS battery that had to be changed on the motherboard.
In the output of 'isi_hw_status' it was the 'BB VBAT' sensor that was low, but we also got this cluster alert that pointed us in the right direction:
Message: BB VBAT has exceeded Lower Critical threshold: 0.995 (threshold: 2.211)
