FW: Backup Server RAID Array Event Notification

	After I created a pair of two member RAID1 arrays and then added
them as members to a RAID6 array, I am now getting messages similar to the
following, complaining of "Wrong-level" issues.  When I check the RAID6
array, however, it is clean and both RAID1 members are still there.  When I
check both RAID1 arrays, they show clean with no events.  I am running a
compare between all the data on this machine and its mirror (this is a
backup machine).  So far everything looks good.  What does this imply?  Is
there something about which I should be worried?
