How-to Change ILAN on single host Ciena MCP/BluePlanet Install – After the fact

If you started your MCP/BluePlanet install and later found that you have a conflict with the default network it uses for its containers, you will need to change it. Here’s a quick how-to:

Change ILAN on single host MCP
==============================

- Get the [MCP Solution name] in solman:

	# solman
	(cmd) sps | grep mcp:
	
	(Eg: artifactory.ciena.com.blueplanet.mcp:18.06.01-2-single)

	
- Do an online backup:
	
	# su - bpadmin
	# cd bpi
	# ./bpi --backup
	(Ignore the "FAILED - RETRYING: Backup - wait to complete" messages)

	
- Confirm backup exits:
    # exit
	# cd /opt/ciena/bp2/snapshots
	# ls -lrth 
	(Last one should be the same as listed at the end of the backup)
	
	
- Stop MCP Solution in solman:

	(cmd) solution_stop [MCP Solution name]
	
  	Can take a long time (20 min)

	
- Stop docker 
    
	(cmd) exit
	# systemctl stop docker

	
- Remove existing DB:

	# cd /opt/ciena/data/docker/network/files
	# rm -rf local-kv.db

	
- Update ILAN IP

	# cd /etc/bp2/site
	# vi ilannet
	# vi /etc/bp2/swarm/swarm_cluster

	Change value. (Eg: 172.16.0.0 to 172.30.0.0)

	
- Stop docker interface:

	# ifconfig dockerbr down

	
- Force ilan change:

	# apply-ilan-config --force
	# bp2-site redeploy
	
- confirm Docker is running (Start docker if not):

	# systemctl status docker
	(# systemctl start docker)
	 
	
- Verify the change

    # solman
	(cmd) sps
	
	IP addresses on the right should all be the new IP.
