Chapter 5: V-Switch Cluster Configuration 79
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.
