[CentOS] semi-OT: hardware RAID and xfs on CentOS 7

Hi, folks,

I'm about to build a filesystem on a CentOS 7 box, on a JetStore RAID box
through a QLogic ISP2532 card. Do I need to specifiy sw and su, or will
xfs query the subsystem and get that itself?

    mark (assuming nixpam lets me through....)
