From this listing, the type of devices, as well as the model name, vendor, and SCSI channel/ID data
is available.
In addition, each SCSI driver used by the system has its own directory in /proc/scsi, which con-
tains files specific to each SCSI controller that uses that driver. So, for the example system above,
aic7xxx and megaraid directories are present, as those two drivers are being utilized. The files in
each of the directories typically contain IO address range, IRQ, and statistics for the particular SCSI
controller that utilizes that driver. While each controller can report a different type and amount of in-
formation, expect the output from most of these files to be very helpful and easy to read. The Adaptec
AIC-7880 Ultra SCSI host adapter's file in our example system produces the following output:
