Some information :
It's a ES45 simplex Tru64 5.1B machine.

Not knowing much, I normally use "doconfig"
to make a new kernel when I add hardware.

You tried what? What didn't work? What,
exactly, did you do? What, exactly,
happened when you did it?

Thanks Steven for replying .
My root file system has been deleted .So i need to restore from the backup .I have booted in single user mode using the cd and mounted the file system .Now i need to mount the tape drive to start the restoration .There's no device name for the tape drive in the output of hwmgr -v d .I tried MAKEDEV tz16 . That created special files like nrmt0h , which i tried to mount but failed .Now i checked the reference pages of Tru64, i found tms and mtio that can be given as parameters to MAKEDEV .But both of them did not work.I thought the tape drive may not be connected well.So just pulled it and put in again.But no changes .
Pls help !

may be you can use
root#dn_setup â install_tape

now it'll work I hope ;)

I booted my XP1000 from the V5.1B CD-ROM (and
exited from the installation procedure).

# ls -lL /dev/tape
ls: /dev/tape not found

# hwmgr -view devices

This shows my tape drive (DLT7000).

# dn_setup -boot

Looks promising.

Looks good to me. I vote for "dn_setup
-boot".
