This makes me think it is a hardware issue, not a software (i.e. Bacula) issue. > Checking /proc/scsi: > [EMAIL PROTECTED] bacula]# cat /proc/scsi/scsi > Attached devices: > Host: scsi0 Channel: 00 Id: 06 Lun: 00 > Vendor: HP Model: C7438ARev: ZP5A > Type:Sequential-AccessANSI SCSI revision: 03 > > Checking with "mt": > [EMAIL PROTECTED] bacula]# mt -f /dev/nst0 status > SCSI 2 tape drive: > File number=0, block number=0, partition=0. > Tape block size 0 bytes.

If so, OK. > I just noticed that /proc/scsi reports "ANSI SCSI revision: 03" and > mt status reports "SCSI 2 tape drive:". Is that an issue? No idea. That may be an OS specific issue... Is the SCSI chain properly terminated? Have you tried a different SCSI cable? A different SCSI terminator? In this image, the cable coming in from the bottom is attached to the computer. The looped cable goes from one SCSI device to another. The block closest to the right is the SCSI terminator. The green light on the terminator indicates the SCSI bus is active. http://www.freebsddiary.org/images/tape-libraries-cables.jpg > Any help here is appreciated! Thanks!
