HP-UX Reference (11i v2 03/08) - 1M System Administration Commands A-M (vol 3)

a
automount(1M) automount(1M)
OSNAME The output of uname -s
. The OS name. For example, HP-UX.
OSREL The output of uname -r. The OS release name. For example,
B.11.00.
OSVERS The output of uname -v. The OS version. For example,
C.
If a reference needs to be protected from neighboring characters, you can surround the variable name
with braces (
{}).
Multiple Mounts
A multiple mount entry takes the form:
key [-mount-options][[mountpoint ][
-mount-options] location ...]...
The initial
/[mountpoint ] is optional for the first mount and mandatory for all subsequent mounts. The
optional mountpoint is taken as a pathname relative to the directory named by key.Ifmountpoint is
omitted in the first occurrence, a mountpoint of
/ (root) is implied.
Given an entry in the indirect map for
/src:
beta -ro \
/ svr1,svr2:/export/src/beta \
/1.0 svr1,svr2:/export/src/beta/1.0 \
/1.0/man svr1,svr2:/export/src/beta/1.0/man
automount would automatically mount /src/beta
, /src/beta/1.0, and /src/beta/1.0/man,
as needed, from either
svr1 or svr2, whichever host is nearest and responds first.
The
autofs mount points must not be hierarchically related.
automount does not allow an autofs
mount point to be created within another autofs mount.
Other Filesystem Types
The automounter assumes NFS mounts as a default filesystem type. Other filesystem types can be
described using the
-fstype mount option. Other mount options specific to this filesystem type can be
combined with the -fstype option. The location field must contain information specific to the filesystem
type. If the location field begins with a slash, a colon character must be prepended, for instance, to mount
a CD filesystem:
cdrom -fstype=hsfs,ro :/dev/sr0
or to perform an autofs mount:
src -fstype=autofs auto_src
Mounts using CacheFS are most useful when applied to an entire map as map defaults (see
cfsadmin(1M)). The following entry in the master map describes cached home directory mounts. It
assumes the default location of the cache directory, /cache.
/home auto_home -fstype=cachefs,backfstype=nfs
Indirect Maps
An indirect map allows you to specify mappings for the subdirectories you wish to mount under the direc-
tory indicated in the /etc/auto_master map or on the command line. In an indirect map, each key
consists of a simple name that refers to the subdirectory of one or more filesystems that are to be mounted
as needed.
Entries in both direct and indirect maps can be modified at any time. The new information is used when
automountd next uses the map entry to do a mount.
Direct Maps
Entries in a direct map are associated directly with
autofs mount points. Each key is the full pathname
of an autofs mount point. The direct map as a whole is not associated with any single directory.
Since each direct map entry results in a new
autofs mount, such maps should be kept short.
If a directory contains direct map mount points, then an
ls -l in the directory will force all the direct
map mounts to occur.
Entries in both direct and indirect maps can be modified at any time. The new information is used when
automountd next uses the map entry to do a mount.
New entries added to a master map or direct map will not be useful until the
automount command is
run to install them as new autofs mount points. New entries added to an indirect map may be used
