thanks for answering, but it seemed it is quite difficult to know if a RAID is a Fake or a real HW RAID, my server (ie S5000PAL) is using 1068 or 1064E RAID chipset to allow using RAID, I don't realy know if it is either a good SW or HW RAID but my boss doesn't want me to use Linux RAID instead of the SW RAID provided by the system itself
I have a pair of 1064's in a server at home and I can confirm they are true hardware RAID. They only support RAID 0, 1, or 10 at most though.
I'm using RAID 10 and for my install RAID is detected, but once I reboot (after the install) the system cannot boot on the OS it seems that I had to use mkinitrd but I don't know how to use it. During installation everything is fine and just before reboot, I got to type some shell command to "tell" the system that he had to use the raid driver at reboot (there is also a problem that I use an USB key to instert the driver and it is viewed as /dev/sda then the system detect the Raid disk and called it /dev/sdb), maybe I had to do something with that before rebooting with a fresh install of XenServer
