How IBM SCSI Adapter Reassigns Drive IDs


The information in this article applies to:

  • Microsoft Windows NT Server version 3.1
  • Microsoft Windows NT Workstation version 3.1
  • Microsoft Windows NT Advanced Server, version 3.1


On older IBM SCSI controllers, the physical drive IDs (what you set the switch or jumper to on the drive itself) are remapped to logical IDs. The controller scans from the highest priority physical ID (6) to the lowest priority physical ID (0) and assigns them in sequential order to logical IDs 0, 1, 2, and so forth.

All software programs and operating systems see the logical IDs just as if they were physical IDs.
