I just have bought an HP HP Proliant ML350 G4. There are four SCSI hard drive configured on RAID 5.0 to act as one 420 GB hard drive. It works and boots perfectly fine with windows 2003 server setup. However when I am trying to setup and boot with small business server 2003 CD it can not detect any hard drive and ask me to check. It seems very strange and I have no clue why it is so. Please guide what can I do to set up SBS2003. I have tried everything and bit frustated.
