Unmounting a File System
Use the umount command to unmount a currently mounted file system.
How to Unmount a File System
To unmount a file system, use the following syntax:
umount special | mount_point
Specify the file system to be unmounted as a mount_point or special (the device on which the file system resides). See the umount_vxfs(1M) manual page for more information about this command and its available options.
Example
To unmount the file system /dev/vx/dsk/fsvol/vol1, enter:
# umount /dev/vx/dsk/fsvol/vol1
To unmount all file systems not required by the system, enter:
# umount -a
This unmounts all file systems except / (root), /usr, /var, /opt, and /tmp.
