Hi Al,

Thank for the answer, the workaround you suggested actually worked on all the 
DELL machines (PE 2950, PE 1950, R510, R410) that had the N/A sensors reading 
problem.
As you said, they were just labeled as disable, but they actually weren't.

Regards,
Daniel

Hi,

The most likely issue you're hitting is a bug on many Dell Poweredge
motherboards.  If you use this workaround, "-W ignorescanningdisabled",
it should work around.  Short description of the workaround, the Dell
motherboards say that a sensor is disabled, but in reality it isn't.

Other possibilities may be that sensors need to be bridged
(--bridge-sensors) or shared sensor outputs need to be enabled
(--shared-sensors).

I'm unsure why ipmi-sensors -v would work.  Would you mind showing
examples of the differences.

Al
