Create the entries in /etc/devlink.tab as described in Creating Tape Links.
If devfsadm has previously discovered the devices, you must determine the device address by running the ls -l command on the existing link.
Be sure to assign /dev/rmt/ N numbers to avoid conflicts with any automatically configured devices, as described above.
Remove existing links from /dev/rmt by running the rm /dev/rmt/* command.
This command creates new links as per the entries in /etc/devlink.tab in addition to automatically creating links for any unspecified devices.
