..I am a little confused about tape devices in FreeBSD. Under the /dev directory...I have the following tape devices: # ls *sa* ersa0 esa0.1 nrsa0.3 rsa0.0 sa0.1 ersa0.0 esa0.2 nsa0 rsa0.1 sa0.2 ersa0.1 esa0.3 nsa0.0 rsa0.2 sa0.3 ersa0.2 nrsa0 nsa0.1 rsa0.3 sa0.ctl ersa0.3 nrsa0.0 nsa0.2 rsa0.ctl esa0 nrsa0.1 nsa0.3 sa0 esa0.0 nrsa0.2 rsa0 sa0.0 I have figured out most of it by searching on the net...but any clarification or pointers to documentation would be helpful. This is what I have figured out so far (feel free to correct me if I am wrong). -e[r]sa0 = Eject -n[r]sa0 = No Rewind -[r]sa0 = Rewind -The .ctl file should be used with the "mt" command. This is what I still need explained: -The difference between the /dev/*rsa0 devices and /dev/?sa0 devices? i.e. What is the "r" for? -What is the .0, .1, .2 and .3? Thanks, Marco
