When umountall and mountall:
/dev/rdsk/c0t12d0s0: is clean.
/dev/rdsk/c0t11d0s0: is clean.
/dev/rdsk/c0t10d0s0: is clean.
/dev/rdsk/c0t8d0s0: is logging.
/dev/rdsk/c0t9d0s7: is logging.
/dev/rdsk/c0t9d0s6: is logging.
/dev/rdsk/c0t9d0s5: is logging.
/dev/rdsk/c0t9d0s0: is logging.
why some says clean and some says logging? They are all treated equally
