Why I am having problems with my real scsi devices after I installed scsi-emulation?
There should be no problem with real scsi devices – scsi emulation is just adding another virtual scsi-controller to your system. So you might have now several controllers and perhaps some device numbering is no longer correct. I have also heard of cases where the previous scsi-controller module no longer gets loaded automatically at startup. In this case just load the module manually by putting this line into /etc/rc.d/rc.
