Red Hat does discontinue support for some storage driver for very old 
hardware when they start a new release series.  For EL6, that list is here:

For 7:

I did a cursory check, and don't see any drivers that were removed in 6 
present in 7.

Run 'lsmod' on the system you're currently running and see if you can 
locate the storage driver.  I'm guessing it's "megaraid" which is not 
present in EL7.
