Planning Disaster Recovery for VMware Aria
Operations for Networks
VMware Aria
Operations for Networks
VMware Site Recovery Manager (SRM) is
a disaster recovery automation software that provides policy-based management,
non-disruptive testing, and automated orchestration. To protect your
VMware Aria
Operations for Networks
, SRM automates every aspect of executing a disaster recovery plan
to accelerate recovery and eliminate the risks involved when using a manual process.
VMware Aria
Operations for Networks
supports SRM version 8.2 and newer versions.For information about
installing, upgrading, and configuring SRM, see
VMware Site Recovery Manager
Documentation.
The prerequisites for the
disaster recovery operation for
VMware Aria
Operations for Networks
are as follows:
- Ensure that you have installed and configured vSphere Replication.
- SRM should be deployed and configured on both the protected and the recovery sites.
- Ensure that the site pairing is configured properly from within the SRM UI before proceeding with the creation of the recovery plan and other components.
- VMware vSphere Replication should be enabled for each of the protected nodes of theVMware Aria Operations for Networkssetup in context. While enabling VMware vSphere Replication, provide sufficient RPO considering theVMware Aria Operations for Networksnode size & the usage so that minimum data loss is expected to incur during a disaster. For more information on replication, see VMware vSphere Replication Documentation.
- Ensure that you create a separate protection group forVMware Aria Operations for Networks. For small and non-distributed deployments, ensure that all the VMs are in the same protection group. For distributed deployments, it is recommended that you place all the platforms in a single protection group so that it is easy to recover. You can place the collectors in different protection groups.
- Create a recovery plan and add the protection groups containingVMware Aria Operations for NetworksVMs to this plan. Ensure that the protection group containing the platform nodes get the higher precedence. In the recovery plan, ensure that the primary platform node is placed in a higher priority group than the other platform nodes.
- Currently, any type of IPv4 customization with SRM is not supported
It is recommended that you
migrate or recover
VMware Aria
Operations for Networks
VMs to an identical network configuration. Also as per
the SRM recommendation, you can perform test run periodically to ensure the
existing plan works with underlying infrastructure and the configured RPO
limit.
- Migrate or recoverVMware Aria Operations for NetworksVMs to an identical network configuration.If the recovery site is configured to have the same network configuration as the protected site and a mapping is created between the identical networks, configure all replicatedVMware Aria Operations for Networksvirtual machines to be started with the same IPs, because these VMs are the protected nodes. The recovered system will become operational after the planned migration or disaster recovery has finished successfully.
- Do not specify any IP customization for a recovery plan when the recovery site does not have the same network as that of the protected site. In this scenario, SRM is used for the recovery of the appliance VMs. For configuring network post recovery, manually assign the network settings as follows:
- Runchange-network-settingscommand on all platforms to change the IP.Ensure that the platform VM reboots successfully before you run the next command.
- Runupdate-IP-changecommand on all the nodes.For example, in a 3-node cluster, to update IP of platform1 from IP1 to IP2, run theupdate-IP-changecommand on platform2 and platform3 with IP1 and IP2 as the arguments. To update IP of platform2, run theupdate-IP-changecommand on platform1 and platform3.
- Runfinalize-IP-changecommand on platform1.
- Run theshow-connectivity-statuscommand on all the collectors and search forPlatform_VM_IP/URLto identify the associated platform nodes.
- Runpair-collector set-platform –-ip-or-fqdn platform-newIPon all collectors.For example, if the CollectorA is associated to platform2, runpair-collector set-platform –-ip-or-fqdn platform2-newIP.
- Check the service status. If some of the services on the platform nodes are not running, reboot the nodes in the recommended order.
