Scenario
In a high-availability (HA) cluster, if either the active or passive node fails or needs a hardware upgrade, the node can be replaced by migrating its disks to a new NAS. This avoids rebuilding the entire cluster and preserves all data and settings.
Procedure
- Prepare a new NAS to replace the old NAS.
Important
- Do not use a different NAS model for replacement. QNAP HA only supports clusters where both NAS devices are of the same model.
- The memory configuration on the new NAS must be the same as the old NAS.
- Do not power on the new NAS at this stage.
- If the old NAS is the active node in the cluster, first perform a switchover.
You can skip this step if the old NAS is already the passive node.- Log in to the old NAS (active node).
- Go to High Availability Manager > Cluster.
- Click Manage, and then select Switch Over.
- After the switchover is complete, ensure the following:
- The other node is now the new active node.
- The cluster status is “Good”.
- Shut down the old NAS (passive node).
- Log in to the other NAS (active node) in the cluster.
- Go to High Availability Manager > Nodes.
- Under the passive node, click
, and then select Shut Down.High Availability Manager shuts down the old NAS.
- Remove all network cables from the old NAS.
Important
Remember which port each network cable is connected to. You will need to connect them to the same ports on the new NAS.
- Transfer all disks from the old NAS to the new NAS.
Important
- Ensure both NAS devices are powered off before you begin.
- You must transfer the disks to the same slots in the same order on the new NAS.
For example, if the old NAS has disk A installed in slot 1, disk B in slot 2, and disk C in slot 5, the new NAS must have the same disk configuration. - We recommend transferring one disk at a time to ensure the order and slot positions are preserved.
- Connect the network cables to the same ports on the new NAS as they were previously connected to on the old NAS.
- Power on the new NAS.
The system will automatically recognize the new NAS as a node and restore the original HA cluster status.

情境
在高可用性 (HA) 叢集 中，如果主動或被動節點故障或需要硬體升級，可以透過將其磁碟遷移到新的 NAS 來替換節點。這樣可以避免重建整個 叢集，並保留所有資料和設定。
程式
- 準備一臺新的 NAS 來替換舊的 NAS。
重要
- 不要使用不同的 NAS 型號進行替換。QNAP HA 僅支援兩台 NAS 設備型號相同的 叢集。
- 新 NAS 的記憶體配置必須與舊 NAS 相同。
- 在此階段不要開啟新 NAS。
- 如果舊 NAS 是 叢集 中的主動節點，首先執行切換。
如果舊 NAS 已經是被動節點，可以跳過此步驟。- 登入舊 NAS (主動節點)。
- 前往 High Availability Manager > 叢集。
- 按一下 管理，然後選擇 切換。
- 切換完成後，確保以下事項：
- 另一個節點現在是新的主動節點。
- 叢集 狀態為「良好」。
- 關閉舊 NAS (被動節點)。
- 登入 叢集 中的另一台 NAS (主動節點)。
- 前往High Availability Manager > 節點。
- 在被動節點下，按一下，然後選擇關閉。
High Availability Manager 關閉舊的 NAS。
- 移除舊 NAS 上的所有網路纜線。
重要
記住每條網路纜線連線到的埠。您需要將它們連線到新 NAS 上的相同埠。
- 將所有磁碟從舊 NAS 轉移到新 NAS。
重要
- 確保在開始之前，兩臺 NAS 裝置都已關閉電源。
- 您必須將磁碟以相同的順序轉移到新 NAS 的相同插槽中。
例如，如果舊 NAS 的插槽 1 裝有磁碟 A，插槽 2 裝有磁碟 B，插槽 5 裝有磁碟 C，則新 NAS 必須有相同的磁碟配置。 - 我們建議一次轉移一個磁碟，以確保順序和插槽位置保持不變。
- 將網路纜線連線到新 NAS 上與舊 NAS 上相同的埠。
- 開啟新 NAS 的電源。
系統將自動識別新 NAS 為一個節點並恢復原始 HA 叢集 狀態。
