Using LSI Logic 21320RB Ultra320 Dual Channel controller, I went into the card bios and set the card to mirror two identical Fujitsu drives. The onboard scsi controller has a single drive attached that has Windows Server 2003 installed as the boot drive. In order for the server to boot from this drive, I had to disable the bios on the LSI Logic card. When I boot the server and go to Disk Management, it shows the C: drive as it should, but it shows the mirrored drives as one dynamic drive ('LSILogic 1030 IM scsi disk device' in Properties) that is set to OFFLINE and I can't get it changed.
My first assumption was that having the controller card do the mirroring would be better - faster - than having Windows handle the mirroring. Is that a correct assumption? If not, I can get it set up with Windows doing the mirroring.
If I SHOULD have the scsi card control the mirroring, how do I get the OS to recognize the drive and show it as ONLINE?
