Is there a tape drive connected?

I need to know if there is a SCSI tape drive connected to my OpenSUSE Linux server. I tried checking the status of /dev/st0 but got an error message: mt: /dev/st0: Input/output error. /proc/scsi/scsi contains the following entries: Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: hp Model: DVD RW AD-7586H Rev: KP03 Type: CD-ROM ANSI SCSI revision: 05 Host: scsi2 Channel: 00 Id: 05 Lun: 00 Vendor: HP Model: C7438A Rev: ZP8B Type: Sequential-Access ANSI SCSI revision: 03 lsscsi output: [0:0:0:0] cd/dvd hp DVD RW AD-7586H KP03 /dev/sr0 [2:0:5:0] tape HP C7438A ZP8B /dev/st0
