problems creating a device link for robot

I tried creating the robot link and I got the following error message

# ls -l /dev/rac/c4t0d0
crw------- 1 bin sys 231 0x040000 Nov 14 05:10 /dev/rac/c4t0d0
# mknod /dev/robot c 203 0x040000
# mc -d /dev/robot -rDS
ERROR: No such file or directory

Try removing the /dev/robot and create a symbolic link of /dev/robot to /dev/rac/c4t0d0

#ln -s /dev/rac/c4t0d0 /dev/robot

Thanks

It really depends upon which driver you need to use --- and that depends upons the host and changer.

First do an lsdev to determine the major device number; 203 may be completely bogus. You will proabably use the scsi pass-thru driver (e.g. sctl, spt, ...) or an autochanger driver. You may, in fact, have to install the appropriate driver in the kernel before using the device. There is just no enough data help to help.
