SANRAD manual Modifying a Cluster, Kai, Routine V-Switch Maintenance 185

Both V-Switches in the cluster must be modified.

Modifying a Cluster

You can modify a cluster’s parameters.

cluster set

You need to define three parameters to modify a cluster’s parameters:

SWITCH	PARAMETER	DEFINITION	STATUS	EXAMPLE
-kai	KEEP ALIVE	TIME BETWEEN	MANDATORY IF	5
	INTERVAL	ALIVE SIGNALS	CHANGING
		FROM NEIGHBORS
-sint	SUSPICIOUS	TIME FROM WHEN A	MANDATORY IF	10
	INTERVAL	SIGNAL WAS	CHANGING
		EXPECTED BUT NOT
		RECEIVED
-fint	FAILOVER INTERVAL	TIME WHEN	MANDATORY IF	10
		SUSPICIOUS	CHANGING
		INTERVAL IS
		EXCEEDED

Enabling and Disabling Failover

If you want to break a cluster or need to take a V-Switch off-line, you must first disable V-Switch failover. Use the CLI command cluster failover disable to disable this functionality. This command must be executed on both V-Switches in the cluster.

cluster failover disable

If you want to restore a cluster or after you bring the V-Switch back on-line, you need to re-enable the failover functionality. Use the CLI command cluster failover enable to re-enable this functionality. This command must be executed on both V-Switches in the cluster.
