] crw-rw-rw-   1 root     sys        9,  0 Jul  2 12:29 tc0
] crw-rw-rw-   1 root     sys        9,  8 Jul  2 12:29 tc0n
] crw-rw-rw-   1 root     sys        9,  1 Jul  2 12:29 tc1
] crw-rw-rw-   1 root     sys        9,  9 Jul  2 12:29 tc1n
] ..(The minor number is the SCSI ID, or +8 for the tcXn device)

Well, I just used newunix tc and then autoconfig and it did it all for me. I
used
	autoconfig -I -o /unix -S /etc/startup -M /etc/master

As fas as formatting, you can use mt(1).  
	mt -f/dev/rmt/tc? format

PS: dont forget to re-kconfig. 8-(
