Example application:
There are two SANs using replication; one of them needs to be moved to a different location so that it synchronizes over the WAN, which means its IP will change.
Solution:
Stop your replication task by clicking on the stop button in CONFIGURATION -> Volume manager -> Vol. replication -> Replication task manager.
Disconnect from your ISCSI initiator.
Change the IP address for the server in question in SETUP -> Network -> Interfaces -> IP address.
On the other server, change the mirror server IP in CONFIGURATION -> Volume manager -> Vol. replication -> Mirror server IP.
Restart your replication task.
Restart your ISCSI initiator, go to Discovery and remove the old portal.
Create a new portal and then connect.
