Chapter 5: V-Switch Cluster Configuration 5-9
Use the CLI command cluster show to view the keep alive parameters of a
cluster.
cluster show
Last Keep Alive KeepAlive Int(s) Susp Int(s) Dead Int(s)
1 2 6 10
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 Chapter 6 “Volume Configuration” for information on
configuring volumes. Please refer to Chapter 7 “Volume Exposure &
Security” for information on exposing volumes.
Please refer to Appendix A “Configuring a Cluster” for a working example of a
full cluster configuration.
