Converting to a standard (non-HA) Central Management System configuration

Use the commands in this section to convert the two nodes in a Central Management System HA configuration to a standard configuration with two independent Central Management System appliances.

Caution

You must convert the secondary node first, and then convert the primary node.

Caution

There will be downtime at the end of the conversion while the Central Management System appliance that was previously the primary node reloads. After it reloads, the managed appliances will resume aggregating alert data to it.

Determine which node is primary:

Log in to either node.
Enable the CLI enable mode:
```
node-hostname > enable
```
Determine which node is primary:
```
node-hostname # show ha status
```
In the command output, look for the Primary Node line under Cluster Status.

Convert the secondary node:

Enable the CLI configuration mode:

node2-hostname > enable
node2-hostname # configure terminal

Stop the cluster engine:

node2-hostname (config) # ha engine stop

Verify that the engine is stopped:

node2-hostname (config) # show ha status

Remove the node from the cluster:
```
node2-hostname (config) # ha node leave
```
When prompted, enter YES (in all uppercase letters) to confirm the removal:
```
Please type YES to confirm leave: YES
```
Disable HA mode:
```
node2-hostname (config) #  no ha enable
```

Disable the HA feature:

node2-hostname (config) #  no cms feature ha available

Save your change:
```
node2-hostname (config) # write memory
```
Power off the Central Management System appliance you converted in the previous steps. (You will power it on again after you convert the primary node.)

Convert the primary node:

Enable the CLI configuration mode:

node1-hostname > enable
node1-hostname # configure terminal

Stop the cluster engine:

node1-hostname (config) # ha engine stop

Verify that the engine is stopped:

node1-hostname (config) # show ha status

Remove the node from the cluster:
```
node1-hostname (config) # ha node leave
```
When prompted, enter YES (in all uppercase letters) to confirm the removal:
```
Please type YES to confirm leave: YES
```
Disable HA mode:
```
node1-hostname (config) #  no ha enable
```

Disable the HA feature:

node1-hostname (config) #  no cms feature ha available

Save your change:
```
node1-hostname (config) # write memory
```
Reboot the Central Management System appliance to complete the conversion to a standard configuration.
```
node1-hostname (config) # reload
```

Example

The following example converts the secondary node to the standard Central Management System configuration.

...

node2 (config) # ha engine stop
success
...				
node2 (config) # show ha status
...
Nodes Status
                              node1        node2
                              running      stopped
...
node2 (config) # ha node leave
Cluster leaving has started
Please check the status with CLI 'show ha configuration'.
node2 (config) # no ha enable
...
node2 (config) # no cms feature ha available
node2 (config) # write memory
Saving configuration file ... Done!
