Jean-Paul,
Our goofy disk formatting is tripping you...
Put the disk space of c8t0d0 in c8t0d0s0 and try the
zpool add syntax again. If you need help with the
format syntax, let me know.
This command syntax should have complained:
pfexec zpool add rpool cache /dev/rdsk/c8t0d0
See the zpool syntax below for pointers.

# zpool add rpool cache c0t1d0s0
# zpool iostat -v rpool
capacity operations bandwidth
