ipmitool sensors. The ipmitool sel list  will tell you actual errors 
logged.  What does the smartctl -a /dev/da# show for the temperatures of 
the hard drives ?  Does smartctl -x show any interesting log entries for 
the drives that threw errors vs the ones that did not ?

memtest will help a bit.  But if its ECC errors typically do get logged 
by the BMC and the ipmitool sel list will typically log those.
