Unmounting File Systems

When you unmount a file system, you make it temporarily inaccessible.
Unmounting does not remove the file system from the disk; you can
make it accessible again by remounting it.
Mounted file systems are automatically unmounted upon executing the
shutdown command. See “Unmounting File Systems Automatically at
Shutdown” on page 610.
You can use either SAM or HP-UX commands to unmount file systems at
other times.
For help in unmounting file systems using SAM, use SAM’s online help.
You get an error
indicating /etc/mnttab
does not exist or that
mount had an
“interrupted system
call” when you try to
mount a file system.
/etc/mnttab is normally created, if it does
not already exist, within
/sbin/init.d/localmount when you boot
up your computer. If you get one of these
messages, /etc/mnttab does not exist.
Recreate it using the mount command
without any options.
On a T-class system,
after adding many file
systems to /etc/fstab
and executing mount -a,
you get a message
including the words
table is full.
See “Reconfiguring the Kernel (Prior to
HP-UX 11i Version 2)” on page 282.
