Preparing the Existing Collectors Nodes (Old Partition Scheme)

To prepare the existing collectors nodes, complete the following:

1. Follow the steps to prepare node B for HA Collector as described in the section above, Preparing Secondary Appliances (Old Partition Scheme).
2. Log in to the administrative shell on the existing node, enter the reset system command, and then enter the repartition command.
3. After repartitioning is complete, run the configure server command.
4. Install the license that should be identical.
5. Reset the admin password in the GUI to match the other system.
6. Log in to the administrative shell on node A, enter the config tunclient command and connect it to the node B OC.
7. You now have two nodes ready for failover configuration where any of them can be primary.
8. If you want to make node B primary, complete the following:
   • Log in to the NetMRI UI of node B (primary) OC and then go to the Settings icon > Setup > Tunnels and Collectors.
   • Choose the existing collector (A), select Collector Replacement, and then insert the Serial Number of node B.
   • Log in to the administrative shell on node B, run the config tunclient command, and then connect it to node B OC (primary).

As the result, you have a new partitioned system (OC (B) and two 2 collectors (A and B)) with prepared secondary devices. Now you can configure a failover pair.
