I had not tried it, but I obtain something consistent to the mentioned
one above:


backup:/boot# lsscsi
[3:0:0:0]    disk    ATA      ST3160211AS      3.AA  /dev/sda


Apparently neither tape drive nor changer is being detected.

I know that SAS disks are seen as SCSI devices (sd*), but external SAS
devices are also seen as SCSI devices? Independent of it, is always the
name of the special file of device /dev/[n]st* for the tape drive and
/dev/sg* for changer?

All these results presented are with Linux 2.6.26-2 from Debian
repositories. Responding to what has been said by James Harper, this
kernel has the CONFIG_CISS_SCSI_TAPE=y option.

Thanks for your reply.

Regards,
Daniel
