SUMMARY
The SCSI ID configuration for Future Domain SCSI controllers is the reverse of the industry standard. The reversal of the SCSI ID is for performance and/or priority reasons on the SCSI BUS.

The Future Domain SCSI adapters use the highest SCSI ID for the boot drive, this is normally ID 6. When adding new SCSI device it will be important to configure the device with a lower SCSI ID then the current boot device.

The following information from the Future Domain Installation Instructions discusses the reasoning behind the reverse ID scheme:

Devices with higher SCSI IDs receive priority from your computer over devices with lower IDs. The controller uses SCSI ID 7, so it is given the highest priority by your computer. You may assign higher IDs to your most often used and fastest devices.

For example, our main SCSI hard drive should be assigned SCSI ID 6 so that it will receive priority over other SCSI devices.

Note: If you have more than one SCSI hard drive, the drive with the highest ID will always be the boot drive.
