Shalom,

The command syntax is similar.

You just need to find the device.

lspci

Should give you initial information.

The GUI hwbrowser should give you enough information to run a command line test.

what is the tape drive model you have?

Here is what worked for me
[root@tnela25n root]# modprobe aic79xx
root]# lsmod
root]# lsmod|grep aic
aic79xx 189020 0 (unused)
diskdumplib 5324 0 [aic79xx]
scsi_mod 115240 4 [aic79xx st ips sd_mod]
root]# mt -f /dev/st0 status
SCSI 2 tape drive:
File number=-1, block number=-1, partition=0.
Tape block size 0 bytes. Density code 0x0 (default).
Soft error count since last status=0
General status bits on (50000):
DR_OPEN IM_REP_EN

"lspci" will list similar to this
