使用 VIOCLI 復原 OpenStack 部署

若要復原 VMware Integrated OpenStack 部署，必須部署 VMware Integrated OpenStack 虛擬應用裝置，並使用 viocli create drrecover 更新 VMware Integrated OpenStack 備份資料，然後使用還原程序復原災難復原站台中的部署。

必要條件

確認在災難復原目標站台中部署 VMware Integrated OpenStack 7.2 OpenStack 虛擬應用裝置。
確認災難復原目標站台的 vCenter 內容程式庫中存在 VMware Integrated OpenStack 備份套件。
發生災難前，必須準備災難復原 YAML 檔案。

程序

在目標站台中建立 vCenter 和 NSX CR。

為管理和運算 vCenter Server 建立 CR。

viocli create vcenter -n 10.155.20.126 -u [email protected] -p ‘xxxxxx’

為 NSX Manager 建立 CR。

viocli create nsx -n nsxmgr01.violab.com -u admin -p ‘xxxxxx!xxxxxx’

擷取 vCenter 和 NSX CR 名稱。

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

計算目標站台中的 Nova 運算名稱。
- 登入管理 vCenter 或運算 vCenter。
- 按一下每個 nova-compute 叢集以從網址列取得 URL。例如：
```
https://<vcenter_server>/ui/app/cluster;nav=h/urn:vmomi:ClusterComputeResource:domain-c8:7e8d8b50-09e4-4cbf-ba52-cab4ae78eba6/summary
```
- 從每個運算叢集的 HTTP URL 中擷取字串 ClusterComputeResource:domain-cx:xxxxxxxx，以重新建立運算節點名稱。
  例如，對於 ClusterComputeResource:domain-c8:7e8d8b50，運算節點名稱為 compute-7e8d8b50-c8。

建立災難復原範本，並編輯來源和目標站台資訊。
```
viocli create drrecover -o > drrecover.yaml
```
使用必要的組態資訊編輯災難復原範本 YAML 檔案。

備註：確保在 YAML 的備份組態區段中設定備份套件災難復原 vCenter 內容程式庫。
使用 drrecover 命令在 vCenter 內容程式庫中產生災難復原套件。
```
viocli create drrecover -f drrecover.yaml
```
確認在災難復原 vCenter 內容程式庫中產生了新的備份套件，例如： backup125-DR-625849。
使用新產生的備份套件 backup125-DR-625849 還原災難復原 vCenter 中的 VMware Integrated OpenStack 部署。如需詳細資訊，請參閱還原部署。

執行還原程序後，您的部署將在災難復原站台中復原。您可以將其用來管理已復原的執行個體、磁碟區和網路。

以下是災難復原範本的範例。您可以檢查組態的詳細資料。
