Daniel, the situation is at follows:
- Normally, RH/FC will see each of the phisical disks as a separate entity.
- As Tom Robinson has said, after you activate RAID1 from BIOS, the OS should see a single logical disk. In order for this to happen, you need ADDITIONAL SOFTWARE DRIVERS. If you are lucky, you might be able to adapt those from HP that you can download from
http://h18000.www1.hp.com/support/files/server/us/locate/1116_6154.html#7. Unfortunately, at a quick glance there seem to exist binary only drivers, only suitable for very old kernels and which most probably will not be useful in FC.
However, IF the so called hardware RAID would have really been hardware, the additional software drivers would not have been needed. Therefore I strongly suggest to give up using the "BIOS" RAID and use a software linux-created RAID1 instead. It is EXTREMELY simple: just DO NOT activate the RAID in BIOS (leave the SATA ports as regular rather then RAID) then go ahead and create the RAID in anaconda (in disk druid actually) when given the opportunity. YOU WILL NOT GAIN ANYTHING using the pseudo-hardware RAID because in fact IT IS STILL DONE IN SOFTWARE, via the drivers available at the above mentioned URL.
As a sidenote: REAL HARDWARE RAID is EXPENSIVE. It ALWAYS includes a separate controller, either on the motherboard or on a separate card. ALL motherboards which pretend to do RAID but require specific software drivers are actually implementing fake-raid. Here are inlcuded both taiwanese made motherboards (all consumer sub-200$ boards) as well as higher priced (Intel, Dell, HP) ones.
And as a last observation: I have implemented linux software RAID several times without a glitch. As long as
http://www.tldp.org/HOWTO/Software-RAID-HOWTO.html is respected, you will not have any problems. It works just as well (or better, since you have additional options and flexibility) as any fake raid.
