/dev/rmt devices are missing

Hello,

I attached a tape drive to one of my partitions but i cannot find the device.
I run the command
Code:
lsdev|grep rmt

but i dont get anything in return.
When i run
Code:
lsslot -c slot

i can see the slot number and the device that belongs to the tape drive but i cannot find any rmt files in /dev.
Why /dev/rmt files are gone and how can i bring them back?

I tried to re-create the files simply by touch but it doesnt work.
My partition is running on UNIX 5.3 environment.

Thank you for your attention

NAME
tcopy - copy a magnetic tape SYNOPSIS
tcopy source [destination] DESCRIPTION
The tcopy utility copies the magnetic tape mounted on the tape drive specified by the source argument. The only assumption made about the contents of a tape is that there are two tape marks at the end. When only a source drive is specified, tcopy scans the tape, and displays information about the sizes of records and tape files. If a des- tination is specified, tcopy makes a copies the source tape onto the destination tape, with blocking preserved. As it copies, tcopy pro- duces the same output as it does when only scanning a tape. The tcopy utility requires the use of Berkeley-compatible device names. For example, example% tcopy /dev/rmt/1b /dev/rmt/2b ATTRIBUTES
