: The [miscGlobalStatus] MIB description is a little woolly however :

: Is there a more detailed explanation of what event will : trigger what status?

We were intentionally vague in describing the status, to allow us the flexibility to change the algorithm in future releases.

The current algorithm is to report "critical" if there are any failed fans, power supplies, or if the chassis temperature is too hot. It reports "nonCritical" if there are any failed disks, or if any volume is 99% full.

: However, when doing : the same power supply pull, we only get a message in the : 'info' file.

I filed a bug report (14576) on this one. Power supply failures are more serious than "info"; we need both to get the severity right, and to make it consistent across the various flavors of reporting.
