Scenario
I have set up a high-availability (HA) cluster with my NAS devices. After logging in to the passive node, I noticed that most features and applications are unavailable, including most functions in High Availability Manager. Is this normal?
Root Cause
In an HA cluster, the active node provides services while the passive node only syncs data from the active node to ensure data consistency and system reliability. The passive node remains in standby mode and does not perform any services. Therefore, most system and configuration functions are restricted on the passive node.
Details
You can still access some applications on the passive node. However, the available features on these applications are mostly limited to specific viewing functions, including:
- High Availability Manager
You can view the HA cluster status and node roles. - QuLog Center
You can check system event logs. - Notification Center
You can review the notification history.
All other services and settings are disabled, until the passive node becomes the active node through a failover or switchover.

场景
我已经使用我的NAS设备设置了一个高可用性（HA）群集。登录到备用节点后，我注意到大多数功能和应用程序不可用，包括High Availability Manager中的大多数功能。这正常吗？
根本原因
在HA 群集中，活动节点提供服务，而备用节点仅从活动节点同步数据，以确保数据一致性和系统可靠性。备用节点保持待机模式，不执行任何服务。因此，大多数系统和配置功能在备用节点上受到限制。
详细信息
您仍然可以访问备用节点上的某些应用程序。然而，这些应用程序上的可用功能大多仅限于特定的查看功能，包括：
- High Availability Manager
您可以查看HA 群集状态和节点角色。 - QuLog Center
您可以检查系统事件日志。 - 通知中心
您可以查看通知历史。
所有其他服务和设置都被禁用，直到备用节点通过故障转移或切换成为活动节点。
