SANRAD manual Enabling and Disabling Failover, Further V-Switch Cluster Configurations

Example:

Every 2 seconds V-Switch 1 sends out a keep alive signal. If, after 6 seconds from the last keep alive signal, V-Switch 1 does not receive another keep alive signal from its neighbor, it enters a suspicious interval. If, after 10 seconds from the last keep alive signal, V-Switch 1 enters a dead interval and begins activating the failover process.

Enabling and Disabling Failover

Once you have configured your cluster parameters, you need to enable the failover functionality. Use the CLI command cluster failover enable to enable this functionality. This command must be executed on both V-Switches in the cluster.

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.

Further V-Switch Cluster Configurations

After configuring neighbor parameters on each V-Switch, you need to configure identical volume configuration and exposure details on each V- Switch in the cluster. Please refer to “Volume Configuration,” page 81, for information on configuring volumes. Please refer to “Volume Exposure & Security,” page 105, for information on exposing volumes.

Please refer to “Configuring a Cluster,” page 272, for a working example of a full cluster configuration.
