Reconfigure DNS and Domain Search on the VMware Aria Operations Analytics Cluster Nodes for Site Protection and Disaster Recovery for VMware Cloud Foundation

To avoid availability disruptions in the VMware Aria Operations analytics cluster during a disaster in the protected VMware Cloud Foundation instance, you reconfigure the domain name and domain search path for all VMware Aria Operations analytics cluster nodes to add the root domain of the recovery VMware Cloud Foundation instance.

Procedure

1. Log in to the primary VMware Aria Operations node by using a Secure Shell (SSH) client at <aria_operations_primary_node_fqdn> as root.

2. Reconfigure DNS and domain search on the VMware Aria Operations Appliance.

   1. Edit the /etc/systemd/network/10-eth0.network file.

      vi /etc/systemd/network/10-eth0.network

   2. In the Network section, add a DNS entry according to your VMware Cloud Foundation Planning and Preparation Workbook, and save the file.

      Note:

      You add an entry for the additional VMware Cloud Foundation instance only.

3. Reconfigure domain search on the on the VMware Aria Operations Appliance.

   1. Edit the /etc/systemd/resolved.conf file.

      vi /etc/systemd/resolved.conf

   2. Modify the Domains entry according to your VMware Cloud Foundation Planning and Preparation Workbook, and save the file.

      Note:

      You add space separated domains.

4. Repeat this procedure for the remaining VMware Aria Operations analytics cluster nodes.
