When replacing a standalone node that is under InCenter control, the following steps should be used:
Remove the old node and replace it with an identical node so its network connections are the same.
Connect to the new node locally and set its management IP address to be the same as the old unit. This will allow InCenter to communicate with it.
Use the export command in the InCenter CLI to force the current configuration into the new node. For example:
admin@InCenter:/> node my-node1 export
This command does not require an activate and commit sequence.
The first time this command is used, an error message will be returned indicating that the host key on the node is different to the host key held by InCenter. This situation is described in the previous section and is solved by changing the stored host key to the correct value shown in the error message. The InCenter CLI command to do this is:
admin@InCenter:/> set StandaloneNode <node-name>
HostKey=<key-value>
