controller Commands
Syntax
controller set automatic_failover 
[/failover_enabled{=boolean}]
/failover_enabled{=boolean}
Specifies whether to turn on or off automatic failover on the 
specified controller. You must set this switch to TRUE if you 
want to turn on automatic failover on the specified controller.
To turn off automatic failover on the specified controller, set 
this switch to FALSE. The command defaults to TRUE, which 
means the command turns on automatic failover on the 
specified controller.
Examples
Before turning the automatic failover feature on or off, check its 
status by using the controller show automatic_failover 
command. 
The following example shows that the controller’s automatic 
failover is currently disabled:
AAC0> controller show automatic_failover
Executing: controller show automatic_failover
Automatic failover DISABLED
The following example turns on (enables) the automatic failover 
feature for the currently opened controller:
AAC0> controller set automatic_failover /failover_enabled
Executing: controller set automatic_failover /failover_enabled=TRUE
The controller show automatic_failover command 
indicates that the controller’s automatic failover is currently 
enabled:
AAC0> controller show automatic_failover
Executing: controller show automatic_failover
Automatic failover ENABLED
