Symptoms

症狀
在這種情況下，簡報伺服器 （管理伺服器） 安裝在 SDS 節點上。

來自主要 MDM 的事件會顯示安裝管理伺服器的 SDS 處於維護模式並重新開機。

When the node boots up, the mgmt-server service initiates but fails when attempting to start the Alert Manager service.

來自管理伺服器的scaleio.log可能會顯示以下錯誤。

影響

警報不會顯示在UI中。

Cause

節點重新開機後，簡報伺服器可能不會顯示警示。此零星問題似乎與節點啟動期間的計時或競爭狀況有關。
