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:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Migration_Planning_Guide/sect-Migration_Guide-Package_Changes-Driver_Changes.html#sect-packages-discontinued-drivers
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Migration_Planning_Guide/sect-packages-deprecated-drivers.html
For 7:
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Migration_Planning_Guide/sect-Red_Hat_Enterprise_Linux-Migration_Planning_Guide-Removed_Drivers.html
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.
Gordon,
