Hi Guys
i onnect tape drive on Redhat 8 server . I try the command mt -f /dev/st0 status and mt -f /dev/st1 status and got the error /dev/st1 No such file or directory. Could someone help to mount the tape drive on my server

tapes are not mounted, they are written to/read from just like a regular file. Does the first command i.e. mt -f /dev/st0 status provide a response or an error message?

What type of tape drive did you connect to your server? What is the make/model. What type of interface does it use? IDE, USB, SCSI etc?

For SCSI you need to make sure the SCSI controller module is being loaded as well as the tape module st.

Thanxs for the replay te model is HP storageWorks Ultinium 960 and the interfac is SCSI. find belong the display of the LS command in /dev

So no tape device exists.
Was the SCSI controller already part of the computer?
Is this a RAID controller?
Post the output of the command lsmod to see if the tape driver st is being loaded.

please find the print

Did you plug the tape drive into the RAID controller?
The tape module is not being loaded.

Try running the command:
modprobe st
