Hi folks,
I'm trying to get my head around the details of tape devices, as in
/dev/st0.
I had thought that for each physical device, two nodes were created
/dev/st0 and /dev/nst0.
The latter does not rewind when closed, thats the one used with bacula.
Untrue! its creates 8 modes. For each on st and nst, there are {a,l,m}
suffixes. These are "scsi modes".
Its documented that these have their own minor device numbers, but I
haven't found anything that explains the significance.
I even had a grovel through st.c but didn't get anything but a pain
behind my eyes.
Any comment on these would be most welcome.
Regards,
John
