FC5 and scsi tape drive troubles

FiveFlat · 07-07-2006, 08:00 PM

I have FC5 installed and my scsi DAT tape drive is detected just fine in dmesg.
However, there is no such device at /dev/st0 or /dev/nst0. FC5 doesn't have the command 'mt' and I have no idea where to go from here. Any help/suggestions would be very welcome!

Regards!

You can get an rpm package of mt from http://rpm.pbone.net

Not at my desktop with scsi dat drive so not sure what to check.
Lets see what the output of the following commands
cat /proc/scsi/scsi

I wonder if the st module is loaded. Type the command ' lsmod ' and post results. Mostly looking for a line like this containing st module

Code:

aic7xxx               134708  11 
scsi_transport_spi     26240  1 aic7xxx
sd_mod                 23168  17 
scsi_mod              132008  6 usb_storage,st,sr_mod,aic7xxx,scsi_transport_spi,sd_mod

and my cat /proc/scsi/scsi

Code:

> cat /proc/scsi/scsi

Finally had time to ssh to my desktop to get this info. I listed all scsi modules loaded on the machine.

If you have no st module then as root use the command to load it.
/sbin/modprobe st

Lets see if that helps.

Here's my results:

Code:

[sheldon@home dev]$ /sbin/lsmod
Module                  Size  Used by
dm_mod                 50009  6 dm_snapshot,dm_zero,dm_mirror
ext3                  116169  2

aic7xxx               129525  0
scsi_transport_spi     21185  1 aic7xxx

scsi_mod              124649  6 st,sg,libata,aic7xxx,scsi_transport_spi,sd_mod

Looks like I infact have it on the bottom line

I've heard it said that FC5 replaced the 'mt' command with 'scsitape' is this true? Even if it is, 'scsitape' results in "command not found".

FiveFlat · 07-08-2006, 11:22 PM

ah ha... I rebooted the system and I noticed that the green led was ON on the front of the tape drive this time. (I originally shoved a tape in there, it loaded and I had no lights) I didn't know that I was supposed to have a green light on simply when the tape is loaded.
so I tried a:

Code:

tar -tf /dev/st0

and it burst into life. So now, I just have to figure out why the hell FC5 doesn't include the 'mt' command.

All distro differ in what they package based on what they believe most users of the distro are going to use.

edit:
Going over to fedora core site and looking through the mirrors site of fc5 rpms, it shows the mt-st package. It can be gotten here. http://mirror.linux.duke.edu/pub/fed...2.2.1.i386.rpm

Now why you may not have it installed may depend on the choices of packages during your installation. So more than likely the rpm is on the install CD or can be gotten from above link.

As far as the LEDs I am not sure since never seen that model or worked with one. Might refer to the manuafactors site for led status.

edit:
To see if you have it installed type ' rpm -qa | grep mt
