Scenario
You want to create a high-availability (HA) cluster with external storage devices connected to the NAS devices. The external storage devices are identical between the two devices and are connected to the same ports or PCIe slots. However, when you try to create an HA cluster in High Availability Manager, the application fails to pair the NAS devices and indicates that they are inconsistent with each other.
Cause
Assuming the two NAS devices are consistent and compatible in all other aspects, HA pairing could fail if you connected the external storage devices to the NAS devices in different chronological orders. This would cause the corresponding external storage devices to have different enclosure IDs between the two NAS devices.
Enclosure IDs are typically assigned to external devices starting from "1", based on the chronological order in which they are connected to the NAS. If the corresponding external storage devices have different enclosure IDs between the two NAS devices, High Availability Manager will consider the two NAS devices to be inconsistent.
Solution
- Check if the enclosure IDs are inconsistent between the two NAS devices.
On each NAS device, go to Storage Manager > Disks > Device to check the enclosure IDs of all external storage devices.
Note
If the enclosure IDs of the external storage devices are all consistent between the two NAS devices, the HA pairing likely failed due to some other inconsistency or incompatibility issue. Please check High Availability Manager for details to resolve the issue.
- Reinitialize the enclosure IDs on both NAS devices.
- For each pair of corresponding external storage devices between the two NAS devices, ensure the external storage devices are connected to the same port or PCIe slot.
- On each NAS device, go to Storage Manager > Disks > Device.
- Click
> Recover > Reinitialize Enclosure IDs.
This action resets all enclosure IDs and assigns each external storage device a new ID number starting from "1", based on the order of the ports and PCIe slots that the external storage devices are physically connected to.
- Ensure the enclosure IDs are consistent.
On each NAS device, go to Storage Manager > Disks > Device to check the enclosure IDs of the external storage devices. Ensure they are consistent between the two NAS devices.
You can now try pairing the NAS devices in the cluster creation wizard in High Availability Manager.

场景
您希望创建一个高可用性（HA）群集，并将外部存储设备连接到 NAS 设备。两个设备之间的外部存储设备是相同的，并连接到相同的端口或 PCIe 插槽。然而，当您尝试在 High Availability Manager 中创建 HA 群集时，应用程序无法配对 NAS 设备，并指出它们彼此不一致。
原因
假设两个 NAS 设备在其他方面都是一致和兼容的，如果您以不同的时间顺序将外部存储设备连接到 NAS 设备，HA 配对可能会失败。这将导致两个 NAS 设备之间的相应外部存储设备具有不同的机箱 ID。
机箱 ID 通常从“1”开始分配给外部设备，根据它们连接到 NAS 的时间顺序。如果两个 NAS 设备之间的相应外部存储设备具有不同的机箱 ID，High Availability Manager 将认为两个 NAS 设备不一致。
解决方案
- 检查两个 NAS 设备之间的机箱 ID 是否不一致。
在每个 NAS 设备上，进入 存储管理器 > 磁盘 > 设备 ，检查所有外部存储设备的机箱 ID。
注意
如果两个 NAS 设备之间的外部存储设备的机箱 ID 都是一致的，HA 配对可能由于其他不一致或不兼容问题而失败。请检查 High Availability Manager 以获取详细信息以解决问题。
- 重新初始化两个 NAS 设备上的机箱 ID。
- 对于两个 NAS 设备之间的每对相应外部存储设备，确保外部存储设备连接到相同的端口或 PCIe 插槽。
- 在每个 NAS 设备上，前往存储管理器 > 磁盘 > 设备。
- 点击 > 恢复 > 重新初始化机箱 ID。
此操作将重置所有机箱 ID，并根据外部存储设备物理连接的端口和 PCIe 插槽的顺序，从“1”开始为每个外部存储设备分配新的 ID 号。
- 确保机箱 ID 一致。
在每个 NAS 设备上，前往 存储管理器 > 磁盘 > 设备 检查外部存储设备的机箱 ID。确保它们在两个 NAS 设备之间一致。
您现在可以尝试在 High Availability Manager 中的群集创建向导中配对 NAS 设备。
