humm... it should detect it fine. 
According to: 

http://www.redhat.com/docs/manuals/linux/RHL-7.2-Manual/ref-guide/s1-modules-scsi.html

it should use the megaraid module and be supported and not need any
other parameters. ;(  

You could try booting the 7.2 with 'linux expert' and epecifically
make it load the megaraid module.  

You can also go to the vty on alt-f4 and alt-f5 and see if it has any
error messages.  

Finally, you can try the updated boot image at:
https://www.redhat.com/support/errata/RHBA-2002-016.html

it doesn't mention the megaraid as being fixed, but it might be... 
that will of course be in the next KRUD version if you want to wait.

not really. You can update packages, but doing that between release
versions is likely to get your machine confused or otherwise subtly
messed up.
