about 4 years ago, I tried to install CentOS 6 on a Supermicro server with SCSI drives using a LSI raid system.
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.
