Optional Configuration Tasks
Adding the LifeKeeper GUI Icon to the Desktop Toolbar
The LifeKeeper GUI icon is automatically added to the desktop menu under the System sub-menu
during installation of the LifeKeeper GUI package. (If the icon does not appear, then logout and then
login again.) If you also wish to add the icon to your desktop toolbar, do the following:
Note: The location of the System menu may vary depending on the Linux distribution you are using.
Changing the Icon Position
In either Gnome or KDE, if you wish change the location of the LifeKeeper GUI icon on the toolbar, do
the following:
1. Right-click on the LifeKeeper GUI icon on the toolbar and choose Move (or Move Applet).
2. You can now move the icon across the length of the toolbar.
3. Left click on the desired location to anchor the icon in its new location.
Configuring the Manual Failover Confirmation Option
In certain configurations, it may be desirable to require manual confirmation by a system
administrator before allowing LifeKeeper to perform a failover recovery of a system that it detects as
failed. This capability can be used to prevent LifeKeeper from performing failovers in situations where
LifeKeeper detects that a remote system has crashed when it actually has not. This situation is
possible in configurations that do not include redundant heartbeat communications paths.
This option is configured by setting the confirmso!uname flag on the system which will be
performing the failover recovery, where uname refers to the name of the remote system which has
failed. See theLCDI-flag(1M) manual page.
When this flag is set and LifeKeeper determines that the indicated system has failed, the lk_
confirmso(1M)command must be used to confirm or block switchovers. See the lk_
confirmso(1M) manual page for details on its use, and for information about modifying the default
timeout and action values associated with this feature, as specified by the CONFIRMSOTO and
CONFIRMSODEF tunables in /etc/default/LifeKeeper.
Setting Server Shutdown Strategy
The Shutdown Strategy is a LifeKeeper configuration option that governs whether or not resources
are switched over to a backup server when a server is shut down. The options are:
