If you are trying to assign virtual hostname for internal manager/standard manager it may not be possible in 12.1.3. As 12.1.3 needs cm to be attached to physical hostname.
If you are trying to add additional new node to current setup and want to enable CM on the new node, you can disable batch processing service group on current node and enable on other node. Below are the steps to be performed after adding node.
1) Shutdown services
2) On current node modify value of "s_batch_status" in context file to "disabled"
3) Run autoconfig
4) On new node, ensure that "s_batch_status" has value set to "enabled", if not please update.
5) Run autoconfig and then bounce services.
Can you share the requirement. did you recently changed the host name ? (or) you added new servers recently?
Please check the node details.
