System Administration Commands lumount(1M)
NAME
lumount, luumount - mount or unmount all file systems in a
boot environment
SYNOPSIS
/usr/sbin/lumount [-l error_log] [-o outfile] BE_name
[mount_point] [-X]
/usr/sbin/lumount
/usr/sbin/luumount [-f] { [-n] BE_name | [-m] mount_point |
block_device} [-l error_log] [-o outfile] [-X]
DESCRIPTION
The lumount and luumount commands are part of a suite of
commands that make up the Live Upgrade feature of the
Solaris operating environment. See live_upgrade(5) for a
description of the Live Upgrade feature.
The lumount and luumount commands enable you to mount or
unmount all of the filesystems in a boot environment (BE).
This allows you to inspect or modify the files in a BE while
that BE is not active. By default, lumount mounts the file
systems on a mount point of the form /.alt.BE_name, where
BE_name is the name of the BE whose file systems are being
mounted. See NOTES.
When invoked with no arguments, lumount returns the name(s)
of the mounted BEs on a system.
The lumount and luumount commands require root privileges or
the Primary Administrator role.
OPTIONS
The lumount and luumount commands have the following
options:
-f
For luumount only, forcibly unmount a BE's file systems
after attempting (and failing) an unforced unmount. This
option is analogous to the umount(1M) -f option.
-l error_log
Error and status messages are sent to error_log, in
addition to where they are sent in your current environ-
ment.

System Administration Commands lumount(1M)
-m mount_point
luumount unmounts the file systems of the BE that owns
mount_point. See description of mount_point under
OPERANDS, below. The use of -m is optional when specify-
ing a mount point for luumount.
-n BE_name
Name of the BE whose file systems will be unmounted. See
description of BE_name under OPERANDS, below. The use of
-n is optional when specifying a BE name for luumount.
-o outfile
All command output is sent to outfile, in addition to
where it is sent in your current environment.
-X
Enable XML output. Characteristics of XML are defined in
DTD, in /usr/share/lib/xml/dtd/lu_cli.dtd.<num>, where
<num> is the version number of the DTD file.
For luumount, if you supply an argument and specify neither
-m nor -n, the command determines whether your argument is a
BE name, a mount point, or a block device. If it is one of
these three and the argument is associated with a BE that
has mounted file systems, luumount unmounts the file systems
of that BE. Otherwise, luumount returns an error.
OPERANDS
BE_name
Name of the BE whose file systems will be mounted or
unmounted. This is a BE on the current system other than
the active BE. Note that, for successful completion of
an lumount or luumount command, the status of a BE must
be complete, as reported by lustatus(1M). Also, none of
the BE's disk slices can be mounted (through use of
mount(1M)).

System Administration Commands lumount(1M)
mount_point
For lumount, a mount point to use instead of the default
/.alt.BE_name. If mount_point does not exist, lumount
creates it. For luumount, the BE associated with
mount_point will have its file systems unmounted. Note
that default mount points are automatically deleted upon
unmounting with luumount. Mount points that you specify
are not deleted.
block_device
For luumount only, block_device is the root slice of a
BE, such as /dev/dsk/c0t4d0s0. luumount unmounts the
file systems of the BE associated with block_device.
EXAMPLES
Example 1: Specifying a Mount Point
The following command creates the mount point /test and
mounts the file systems of the BE second_disk on /test.
# lumount second_disk /test
/test
You can then cd to /test to view the file systems of
second_disk. If you did not specify /test as a mount point,
lumount would create a default mount point named
/.alt.second_disk.
Example 2: Unmounting File Systems
The following command unmounts the file systems of the BE
second_disk. In this example, we cd to / to ensure we are
not in any of the file systems in second_disk.
# cd /
# luumount second_disk
#
If /dev/dsk/c0t4d0s0 were the root slice for second_disk,
you could enter the following command to match the effect of
the preceding command.
# cd /
# luumount /dev/dsk/c0t4d0s0

slashes with colons in a default mount point name. For exam-
ple:
# lumount 'first/disk'
/.alt.first:disk
