lumount, luumount - mount or unmount all file systems in a boot environment


lumount [ -l error_log ] [ -o outfile ] BE_name [ mount_point ] luumount [ -l error_log ] [ -o outfile ] BE_name


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.<num>, where <num> is a random number. The lumount and luumount commands require root privileges.


The lumount and luumount commands have the following options: -l error_log Error and status messages are sent to error_log, in addition to where they are sent in your current environment. -o outfile All command output is sent to outfile, in addition to where it is sent in your current environment.


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 comple- tion 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)). mount_point For lumount only, a mount point to use instead of the default /.alt.<num>. If mount_point does not exist, lumount creates it. SunOS 5.8 Last change: 22 Oct 2001 1 Maintenance Commands lumount(1M)


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. 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 #


The following exit values are returned: 0 Successful completion. >0 An error occurred.
