the other nice thing about this is that (if you’ve already had to set MapBuffers) you can use vendor specific commands to the LUN to do your configuration rather than miniport IOCTLs which have more performance issues.
please, please, please, please, please do NOT make your fake device SCSI_DISK or any other useful storage class (cdrom, tape, etc…)
if you do expose a fake device, you should expect to ship a scsi device INF which has an entry for your fake device and silently installs no driver. Otherwise your customers hit device popups. (this may not be necessary for SCSI_OTHER, but for SCSI_PROCESSOR we have no idea whether the device is a RAID controller, some other server type device, or a consumer printer and we need to ask for drivers to resolve the last case)

To: NT Developers Interest ListAh good point. The solution to this bug is for the miniport
to create a target that is always present. SCSI_PROCESSOR or
SCSI_OTHER usually works.===========================
