Where can I find the meaning of the device files in /dev/rmt

0?

0mnb?

Hi

Use lssf /dev/rmt/* or use sam to look at the tape device and you have an option to see the device files.

The device files work like this:

0m is an AT&T style device
0mb is a Berkely style device
0mn is an AT&T - no rewind device
0mnb is a Berkely - no rewind device

Generally, you'll only be using the AT&T device files: 0m and 0mn

David,

You can also get this information by going into SAM > Peripheral Devices > Tape Drives, then selecting a drive and looking at Actions > Show Device Files.
