lu - FMLI-based interface to Live Upgrade functions




The lu program is part of a suite of commands that make up the Live Upgrade feature of the Solaris operating environ- ment. 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 sub- set of the functions provided by the lucreate(1M) and luupgrade(1M) command-line utilities. 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 equivalent 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) utility. 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. Equivalent of the command- line lucreate(1M) utility. Current Display the name of the current boot environment. SunOS 5.8 Last change: 8 Jun 2001 1 Maintenance Commands lu(1M) 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. Equivalent of the command- line luupgrade(1M) utility. 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 system). 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. SunOS 5.8 Last change: 8 Jun 2001 2 Maintenance Commands lu(1M) The lu command supports only single-byte environments. Common Functions Most of the options listed above offer the following func- tions. 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.
