haFailover Forces the failover mechanism so that the standby control processor (CP) becomes the active CP. Synopsis hafailover Availability admin Description Use this command to force the failover mechanism to occur so that the standby CP becomes the active CP. Because haFailover results in an active CP reboot, a warning message and confirmation are displayed. If the user confirms, the failover takes place. When HA synchronization is enabled and the CPs are in sync, the port traffic light does not flash during the failover, even while traffic is continuing to flow. NOTE: This command is supported only on systems with dual CP cards. Operands none Examples To force the failover of the active CP to the standby CP in the switch: switch:admin> hafailover Local CP (Slot 6, CP1): Active Remote CP (Slot 5, CP0): Standby, Healthy HA enabled, Heartbeat Up, HA State synchronized Warning: This command is being run on a redundant control processor(CP) system. If the above status does not indicate 'HA State synchronized', then the CPs are not synchronized and this operation will cause the active CP to reset. This will cause disruption to devices attached to both switch 0 and switch 1 and will require that existing telnet sessions be restarted. To reboot a single logical switch on this system, use the switchreboot command while logged in to that logical switch.
