If you use "zpool create -f <pool name> <7th slice>", yes, it'll destroy
the filesystem that's on that slice and you won't be able to access any
of the data presently on it.
If you do "zpool create pool <7th slice>"
where <slice> has a UFS filesystem, and is mounted, it should print an
error message, saying that
a) there's a filesystem present
b) it's mounted
- so you need to unmount it, and use the -f flag.

In more detail:
(snip newfs of c2t1d0s1 to put a UFS filesystem on it)
# mount /dev/dsk/c2t1d0s1 /tmp/a
# zpool create pool c2t1d0s1
invalid vdev specification
use '-f' to override the following errors:
/dev/dsk/c2t1d0s1 is currently mounted on /tmp/a. Please see umount(1M).
# umount /tmp/a
# zpool create pool c2t1d0s1
invalid vdev specification
use '-f' to override the following errors:
/dev/dsk/c2t1d0s1 contains a ufs filesystem.
# zpool create -f pool c2t1d0s1
