Emergency shutdown: Number of Failed chassis fans are more than tolerable limit. Shutting down now

Hi,

We are still burning in a new 3170 clusters running 7.3.3 - last night one of the heads logged:

 Emergency shutdown: Number of Failed chassis fans are more than tolerable limit. Shutting down now

Shortly after midnight last night.
When I went to check it this morning there were no fans failed (no amber lights on) and the head was sitting at the LOADER prompt.
I typed 'bye' and it came up fine waiting for giveback.

This is less than confidence inspiring - we want to cutover production to this cluster and having it flake out on a seemingly  non-existent fan issue is troubling.
Anyone else seen this or anything like it?
All HW diags appear green - do I have a faulty piece of hardware or not?

thanks,
Fletcher

Fletcher,

The fact the the system was sitting at the LOADER prompt meant it rebooted & this most likely cleared any amber lights that might have existed. What did the messages log record during this timeframe? If one controller didn't record the problem, the partner might have, so look on both.

Peace,

Shane
