Sata drive install

[gato]

To all
I am trying to install CentOS 5.2 on a HP proliant DL320 G4. (Sata SmartArray P400) It seems to me that the OS can't see the drives.
this is what I have done so far
I tried to install the CentOS 5.2 with defaults settings (centOS sees the hard drive at raid 0 hardware raid) at first it seems that the OS was installed properly no error message what so ever,
but when CentOS it is trying to boot up I get error messages

dev/sda2: read failed after 0 to 1024 at 15619678208:input output error
no volume groups founds
volume group "vlogroup00" not found
buffer I/O on device sda2
unable to access resume device (/dev/vougroup00/logvol01)
mount could not find file system /dev/root
setuproot moving /dev failed not such a setuproot error moutnting /proc no such file or directory
setuproot error mounting /system not such file or director
Kernet panic not syncing attenpted to kill init!

Is my assumption correct or it is something else?

thanks for your help in advance

Are you using a ramdisk? What's the output of ls -l /boot, and what's in /boot/grub/menu.lst? (You can use a rescue disk such as Knoppix to access these details. This tutorial might give you the idea: http://www.howtoforge.com/how-to-reset-a-forgotten-root-password-with-knoppix )
