Recover OpenStack Deployment Using VIOCLI

To recover your VMware Integrated OpenStack deployment, you must deploy VMware Integrated OpenStack virtual appliance, and use viocli create drrecover for updating the VMware Integrated OpenStack backup data, and then use restore procedure for recovering the deployment in the disaster recovery site.

Prerequisites

Verify that you deploy VMware Integrated OpenStack 7.2 OpenStack virtual appliance in the disaster recovery target site.
Verify that there is a VMware Integrated OpenStack backup package in the vCenter content library in the disaster recovery target site.
Before disaster, you must prepare the disaster recovery YAML file.

Procedure

Create the vCenter and the NSX CR in target site.
1. Create CR for management and compute vCenter servers.
```
viocli create vcenter -n 10.155.20.126 -u [email protected] -p ‘xxxxxx’
```
2. Create CR for NSX manager.
```
viocli create nsx -n nsxmgr01.violab.com -u admin -p ‘xxxxxx!xxxxxx’
```
3. Retreive the vCenter and NSX CR names.
```
viocli get vcenter
NAME              CREATION DATE            VALIDATION
vcenter155        2021-04-28 14:03:17      Success
vcenter388        2021-04-28 14:02:12      Success
viocli get nsx
NAME              CREATION DATE            VALIDATION
nsx950            2021-04-28 14:05:10      Success
```
4. Calculate Nova compute name in the target site.
  - Log in to the management vCenter or compute vCenter.
  - Click each nova-compute cluster for obtaining the URL from the address bar. For example:
```
https://<vcenter_server>/ui/app/cluster;nav=h/urn:vmomi:ClusterComputeResource:domain-c8:7e8d8b50-09e4-4cbf-ba52-cab4ae78eba6/summary
```
  - Extract the string ClusterComputeResource:domain-cx:xxxxxxxx from the http URL for each compute cluster for reforming compute node name.
    For example, for ClusterComputeResource:domain-c8:7e8d8b50, compute node name is compute-7e8d8b50-c8.
Create the disaster recovery template and edit the source and target site information.
```
viocli create drrecover -o > drrecover.yaml
```
Edit the disaster recovery template YAML file with the necessary configuration information.

Note: Ensure that you configure the backup package disaster recovery vCenter content library in the backup configuration section in YAML.
Generate a disaster recovery package in vCenter content library using the drrecover command.
```
viocli create drrecover -f drrecover.yaml
```
Verify that there is a new backup package generated in the disaster recovery vCenter content library, for example: backup125-DR-625849.
Use the new generated backup package backup125-DR-625849 for restoring the VMware Integrated OpenStack deployment in the disaster recovery vCenter. For more information, see Restore Deployment.

After restore procedure, your deployment is recovered in the disaster recovery site. You can use it to manage the recovered instances, volumes, and networks.

Following are the examples for the disaster recovery tempate. You can check the details for the configurations.
