NAME

       lu - FMLI-based interface to Live Upgrade functions

SYNOPSIS

       /usr/sbin/lu

DESCRIPTION

       The  lu  program  is  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 lu program is a Forms and Menu Language Interpreter-based user interface. (See fmli(1) for a description of the Forms and Menu Language
       Interpreter.)  lu  enables  you to create and upgrade boot environments (BEs) and perform other administrative tasks on BEs. The lu program
       performs a subset of the functions provided by the Live Upgrade command-line utilities.

       Users of lu should be aware of the following:

         o  lu is a deprecated interface. It will be replaced in the future and should not be depended on for critical functionality.

         o  All new Live Upgrade features are being implemented in the Live Upgrade command-line utilities. No new features are being made  avail-
            able in lu.

         o  The lu command is not internationalized. It will not be internationalized in a future release.

       lu  should be used for learning or experimenting only. For any production use or to use the full capabilities of Live Upgrade, use the Live
       Upgrade command-line utilities.

       Invocation of the lu command requires root privileges.

       The lu command accepts no arguments. After invoking lu, you receive a display with the following options:

       Activate

           Activate a boot environment. This option designates that the system boot from the specified BE upon next reboot. This option is equiva-
           lent to the command-line luactivate(1M) utility.

       Cancel

           Cancel  a  copy  job. Live Upgrade allows you to schedule the copy, upgrade, and flash functions (all described below) at a later time.
           The cancel function enables you to cancel a scheduled job. This function is equivalent to the command-line lucancel(1M) utility.

       Compare

           Compare the contents of BEs. Enables you to obtain a detailed comparison of two BEs. Equivalent to the command-line lucompare(1M) util-
           ity.

       Copy

           Start/schedule  a  copy.  Copies the contents of one BE to another. Equivalent of the command-line lumake(1M) utility. At any time, you
           can have only one Live Upgrade operation scheduled.

       Create

           Create a boot environment. Implements a subset of the functions performed by the command-line lucreate(1M) utility.

       Current

           Display the name of the current boot environment. Equivalent of the command-line lucurr(1M) utility.

       Delete

           Delete a boot environment. Equivalent of the command-line ludelete(1M) utility.

       List

           List the file systems of a boot environment. Equivalent of the command-line lufslist(1M) utility.

       Rename

           Change the name of a boot environment. Equivalent of the command-line lurename(1M) utility.

       Status

           List the status of all boot environments. Equivalent of the command-line lustatus(1M) utility.

       Upgrade

           Upgrade a boot environment or upgrade the OS on an inactive BE. This option enables you to upgrade to a new operating system or install
           new  packages  or  patches on a specified BE. Implements a subset of the functions performed by the command-line luupgrade(1M) utility.
           Note that if you are performing an upgrade that requires more than one CD, you must use the -i option of luupgrade.

       Flash

           Flash a boot environment. This option enables you to install an operating system on a BE from a flash archive. You can perform the same
           function with luupgrade(1M).

       Help

           Displays help information. There are also context-specific help screens for many of the options.

       Exit

           Exit lu.

   Navigation
       You  navigate  through lu's various screens using arrow keys and function keys (usually F2 through F9 on the keyboard of a Sun desktop sys-
       tem). Available key functions are displayed at the base of the lu screen. You can use Ctrl-F, plus a number key, to  duplicate  a  function
       key. For example, press Ctrl-F and the number key 2 to duplicate the F2 key.

       In a screen for a given option, you can press Esc to obtain context-specific help.

   Display Issues
       When viewing the FMLI interface remotely, such as over a tip line, you might need to set the TERM environment variable to VT220. When using
       the FMLI interface in a CDE environment use dtterm, rather than xterm, as the value of the TERM variable.

       The lu command supports only single-byte environments.

   Common Functions
       Most of the options listed above offer the following functions. These functions are accessible through function keys indicated at the  base
       of the screen.

       Choice

           Available  to you whenever you have a field that can be filled in. Pressing the Choice function key gives you a popup screen displaying
           a list of alternatives. For example, for options involving copying or upgrading BEs, you receive a list of available BEs.  You can then
           use  arrow  and function keys to make a selection from this popup. The choice function is useful because it prevents you from selecting
           an invalid alternative. In our example, it prevents you from choosing a BE that is not available for a copy or upgrade operation.  Such
           non-availability might occur when a BE is in the midst of an upgrade.

       Cancel

           Cancel an operation.

       Save

           Proceed with an operation.

   Other Functions
       The "Create" option, described above, offers the following functions:

       Split

           Split  a  file  system.  For  example, you can split a / file system into /, /usr, and /var. To split a file system, you must have disk
           slices available on which to mount the separated file system(s). If you do not, lu invokes the format(1M) utility, in which you can use
           the partition option to create a new disk slice.

       Merge

           Join  one  or  more  file systems with its (or their) parent file system. For example, using a source BE that has separate /, /usr, and
           /var file systems, you can merge these file systems under / on a target BE.

FILES

       /etc/lutab

           list of BEs on the system
