SYNOPSIS
mount [-l][-v
|-p]
mount [-F vxfs ][-eQ
] -a
mount [-F vxfs ][
-eQrV][-o specific_options ]{special |directory }
mount [-F vxfs ][-eQrV

umount [-F vxfs ][-v
] -a
DESCRIPTION
mount attaches special , a removable file system, to directory , a directory on the file tree. (This directory
is also known as the mount point). directory , which must already exist, becomes the name of the root of
the newly mounted file system. If you omit either special or directory,
mount attempts to determine the
missing value from an entry in
/etc/fstab.
mount can be invoked on any removable file system,
except /. special and directory must be given as absolute path names.
mount notifies the system that special , a VxFS block special device, is available to users from
mount_point , which must exist before mount is invoked. mount_point becomes the name of the root of
the newly mounted file system special.
Large files (over two gigabytes) are supported on HP-UX 10.20 systems and above.
Unlike some file system commands, you cannot specify multiple
-o options to mount; only the last option
is used.
If you invoke
mount with no arguments, it lists all the mounted file systems from the mounted file system
table, /etc/mnttab.
The
umount command unmounts mounted file systems.
The
vxumount command provides a force option to unmount mounted file systems.
Only the superuser can
mount and umount file systems. Other users can use mount to list mounted file
systems.
Options
mount recognizes the following options:
-a Attempts to mount all file systems described in /etc/fstab. All optional fields in
/etc/fstab must be included and supported. If -F vxfs is specified, all VxFS file sys-
tems in /etc/fstab are mounted. If noauto is specified in an entry’s option list (in
/etc/fstab), that entry is skipped (not mounted). File systems are not necessarily
mounted in the order listed in /etc/fstab.
-e Verbose mode. Writes a message to the standard output indicating which file system is
being mounted.
-F vxfs
Specifies the file system type (vxfs).
-l Limits actions to local file systems only.
-o specific options
Specifies options specific to the VxFS file system type. See the "Specific -o Options" topic in
this section..
-p Reports the list of mounted file systems in /etc/fstab format.
-Q Prevents display of error messages, resulting from an attempt to mount already mounted
file systems.
-r Mounts the specified file system as read-only. Physically write-protected file systems must
be mounted in this way or errors occur when access times are updated, whether or not any
explicit write is attempted.
