Device Driver Numbering - SunOS 4.1.x

SUN's minor device naming abovemay seem to imply that the minor device corre-

sponds to the SCSI ID. In general, this is not the case. For example, on a typical

Sun 4/470 kernel, tape devices are congured in the kernel such that the following

Thus, the mapping from SCSI ID's to minor devices is as follows:

Thus, although (18,4) and (18,5) would correspond to SCSI ID's 4 and 5 respectively,
