You need to do a few more things to get where you want to be.
1) do a fsck on root
/etc/fsck -y /dev/dsk/0s1
2) mount root
/etc/mount /dev/dsk/0s1 /mnt
3) cd to the hard disc root
cd /mnt
4) if you want - set your path to reflect the current environment
PATH=/mnt/bin:/mnt/usr/bin:/mnt/etc:/mnt/usr/lib
export PATH
5) now you can get to all the files on your hard disc, but remember
that your 'root' file system is really one level down,
ie. / = /mnt
6) do whatever you need to do (ie. edit /mnt/etc/passwd) and then
unmount the disc
cd /
/etc/umount /dev/dsk/0s1
7) sync the disc tables
sync;sync;sync
8) reboot
uadmin 2 0
All should be again well with the world, with the exception of the
Middle East.

Don't know what your original question was, so am making an assumption
that you have a "standard" scsi 60meg tape drive, in which case, I have
had excellent success using 3M DC600HC tapes in mine.
