Confirm Failover and Block Resource Failover Settings
In certain configurations, it may be desirable to require manual confirmation by a system
administrator before allowing SPS to perform a failover recovery of a system that it detects as failed.
This capability can be used to prevent SPS from performing failovers in situations where SPS detects
that a remote system has crashed when it actually has not. This situation is possible in configurations
that do not include redundant heartbeat communication paths.
Make sure you review and understand the following descriptions, examples and considerations
before setting Confirm Failover or Block Resource Failover in your SPS environment. These
settings are available from the command line or on the Properties panel in the LifeKeeper GUI.
Confirm Failover On
The Confirm Failover On setting allows you to require manual confirmation of failovers from specific
systems in the SPS cluster. It is only available to SPS administrators. Operators and guests will not
be able to see it. By default, all failovers proceed automatically with no user intervention. However,
once the Confirm Failover flag is set, failovers from the designated system will require confirmation.
Execute one of the following lk_confirmso commands to confirm the failover:
To proceed with failover:
lk_confirmso -y system
To block failover:
lk_confirmso -n system
By default, the administrator has ten minutes to run this command. This time can be changed by
modifying the CONFIRMSOTO setting in /etc/default/LifeKeeper. CONFIRMSOTO is set to the
