[Linux-PowerEdge] hard disk predictive failures and snmp

You may want to look at smartd.  smartd can email you about SMART errors 
and run custom scripts when a problem occurs.  It works well for us.

I don't think that hard drives, RAID cards, etc usually communicate with 
the BMC (aka iDRAC) so it wouldn't have that information at the hardware 
level.  I could be wrong but that certainly seems to be the case.
