I purchased 2 Ultra320 SCSI HD for my DL360G4p, however, when I boot it up and go to the BIOS I don't see the drive beeing recognized. I was able to boot Centos 5.5 liveCD from USB. The only change I remember doing was flashing the BIOS. I don't think that would cause an issue. I'm thinking there might be a RAID configuration isssue but that doesn't explain why the BIOS isn't identifying the 2 HD.
