slow in Oracle Linux 6.2

I was going thru the logs in /var/log/messages and I came across some Storage Service Events. While they may or may not indicate a problem, many of these occurred after ywe completed the last build out of the file system and many days after Dell had swapped out the drives.  See an extract below:

After reading your question: called Dell already? They have swapped hardware, now you have messages you did not have before.
