Symptoms
在這種情況下，簡報伺服器 （管理伺服器） 安裝在 SDS 節點上。
來自主要中繼資料管理員 （MDM） 的事件表示安裝管理伺服器的 SDS 正在進入維護模式並重新開機。

當節點啟動時，管理伺服器服務將啟動，但在嘗試啟動警報管理器服務時失敗。
來自管理伺服器的scaleio.log可能會顯示以下錯誤。

...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。
Resolution
若要解決此問題，請重新啟動 mgmt-server 服務以取回警示。
systemctl restart mgmt-server.service
