Changing device names

[Glenn Mitchell_4]

I need to change a tape drive device name from /dev/rmt/2m to /dev/rmt/1m. How do I do this?

Hello Glenn,

you can give devicefiles any names you want as long as you stay in the HPUX convention.

You delete the existing device file with the rm command and create a new one with the mknod command.

Make sure that you keep a copy of the old file in a different dir to be on the safe side.

Check the manpage for mknod for the complete syntax.

Hi,

You can just create a link:

ln /dev/rmt/2m /dev/rmt/1m

and it works

But should remember, that 1 and 2 have their meaning.

Use the mknod command to duplicate the device characteristics and change the device name. This always works for me. Hope this helps.

#rmsf -a /dev/rmt/2m
#mksf -C tape -I 1 /dev/rmt/1m

See man rmsf and mksf

The mv command works...
example (0m to 1m):
# cd /dev/rmt
# lssf 0m
stape card instance 0 SCSI target 0 SCSI LUN 0 at&t best density available at ad
dress 16/5.0.0 0m
# mv 0m 1m
# lssf 1m
stape card instance 0 SCSI target 0 SCSI LUN 0 at&t best density available at ad
dress 16/5.0.0 1m

You could also opt to keep the original device file name an create a link to it...
# cd /dev/rmt
# ln -s 0m 1m
