I don't think you can change it without recreating.

What OS version ?

Hello boomerang,

You have the following options with device files:

The command "insf -e -v" recreates device files. The "-e"option creates non-existent device files while the "-v" option re-creates existent device files.

You can manually create device files with the command below:
"mknod /dev/vg01/rvol9 c 64 0x010011"


Regards,
Emmanuel

I hope you are not talking about VG minor number. To do this, see this thread.

If you are talking about a tape device, you can't change it without recreating, but an alternate option, create a hard link to the existing device.
