To prepare the existing OC node, complete the following:
- Follow the steps to prepare node B for HA OC as described in the section above, Preparing Secondary Appliances (Old Partition Scheme).
- To disable SNMP collection on node A, go to the Settings icon > Setup > Collection and Groups > Global > Network Polling and then clear the SNMP Collection checkbox.
- Generate a database archive of node A and restore it on node B. For more information, see NetMRI Database Management.
- If data is restored successfully, proceed to the next step.
- If the restore failed due to disk space exhaustion, try reducing data retention settings on your existing NetMRI system to reduce the archive size. It might take up to 24 hours for reduced data retention settings to take effect. For more information, see Data Retention or contact Infoblox Support for further assistance.
- Run the
configure servercommand on node B. - Run the
config tunservercommand with the new server IP (IP of node B). - To re-enable SNMP collection after restoring the archive on node B, go to the Settings icon > Setup > Collection and Groups > Global > Network Polling and then select the SNMP Collection checkbox.
- Log in to the administrative shell on node A, enter the
reset systemcommand, and then enter therepartitioncommand. - After repartitioning is complete, run the
configure servercommand on node A. - Install the license.
- Reset the admin password in the NetMRI UI to match the other system.
The two nodes are now ready for failover configuration where the primary node is node B with all OC data but without connected collectors at this point.
