Configuring alert replication using the CLI

Use the commands in this section to configure whether aggregated alert data is continuously passed to the secondary node. By default, alert replication is enabled on both nodes. (See Alert replication for information about this configuration option.)

Note

This is a global configuration. The configuration actions are performed from only one node, but are applied to the cluster.

Disabling alert replication

Stop the cluster engine on both nodes:

Enable the CLI configuration mode:

node-hostname > enable
node-hostname # configure terminal

Stop the cluster engine:
```
node-hostname (config) # ha engine stop
```
Repeat these steps on the primary node.

Disable alert replication:

node-hostname (config) # no ha replicate alerts enable

Verify your change:

node-hostname (config) # show ha configuration

Save your change:
```
node-hostname (config) # write memory
```

Restart the cluster engine on both nodes:

Restart the cluster engine on the primary node:
```
node-hostname (config) # ha engine restart
```
Repeat the previous step to restart the cluster engine on the secondary node.

Enabling alert replication

Stop the cluster engine on both nodes:

Enable the CLI configuration mode:

node-hostname > enable
node-hostname # configure terminal

Stop the cluster engine:
```
node-hostname (config) # ha engine stop
```
Repeat these steps on the primary node.

Enable alert replication:

node-hostname (config) # ha replicate alerts enable

Verify your change:

node-hostname (config) # show ha configuration

Save your change:
```
node-hostname (config) # write memory
```

Restart the cluster engine on both nodes:

Restart the cluster engine on the primary node:
```
node-hostname (config) # ha engine restart
```
Repeat the previous step to restart the cluster engine on the secondary node.

Example

The following example disables alert replication on the cluster from the primary node.

node2 (config) # ha engine stop

node1 (config) # ha engine stop
node1 (config) # no ha replicate alerts enable
node1 (config) # show ha configuration
CM HA Cluster Settings:
