To edit the instance network settings

1. From the System topology page of the Flex Appliance Console, navigate to the Application instances section.
2. Locate the instance that you want to edit. If you want to edit the IP address and interface pairs or the default gateway, click Actions > Stop. You do not need to stop the instance to edit the other settings.
3. Click on the instance name to open the instance details page.
   
4. At the top of the details page, click Edit network.
5. Make the required changes. To add or remove IP address and interface pairs, click Manage pairs. To add or remove static routes, click Manage routes.

   Note:

   If you change the protocol of the instance IP addresses, make sure that your configured NetBackup features support the new protocol. For example, if you have configured MSDP cloud on an instance and change the IP protocol to IPv6 only, the SSL setting Check certificate revocation must be disabled.

6. When you are done, click Save.
7. If you changed the IP address and interface pairs for the instance, make sure that you update your DNS configuration or add the new IP addresses to the Hosts file on all hosts that communicate with the instance. If the other hosts are application instances, you can add the new IP addresses to the Hosts file as follows:

   • Follow the previous steps to edit the network of all application instances that need to communicate with the instance that you already edited. On the Edit network page, add the new IP addresses to the Hosts file entries field.

   • Open an SSH session to each instance and run the following commands:

     • sudo /usr/openv/netbackup/bin/bpclntcmd -clear_host_cache

     • sudo mv /usr/openv/var/host_cache /usr/openv/var/host_cache.old

     • sudo bp.kill_all

     • sudo bp.start_all
