# mount -F pcfs /dev/diskette /pcfs
Unmounting File Systems
# umount /export/home ==> unmount using directory mount point
# umount /dev/dsk/c0d1s7 ==> unmount using logicak disk device name
# umountall ==> to unmount all filesystems listed in /etc/mnttab file
# umountall -l ==> to unmount only local filesystems
