ECS:OBS: xDoctor:RAP073/208:偵測到交換器連線故障
摘要: 本知識庫說明如何處理偵測到交換器連線故障警示。
症狀
從 ECS xDoctor v4.8-109.0 和 ObjectScale xDoctor v5.1-109.0 開始, RAP208 (偵測到交換器連線故障) 已實作為 自動修復程式。當交換器連線問題超過設定 的錯誤 或 嚴重 性閾值時,xDoctor 會發出 RAP208 警示,並自動啟動其整合式修復協調流程。如果已 啟用 xDoctor 自動修復程式,此工作流程將執行必要的補救動作。
注意:如果您的環境執行的 xDoctor 版本早於 ECS xDoctor v4.8-109.0 或 ObjectScale xDoctor v5.1-109.0,則無法使用 RAP208 自動修復功能。在這些版本中,必須使用下述 AutoPilot 程序執行補救,或依照「解決方法」一節中概述 的手動補救步驟 執行。
觸發 RAP208 自動修復的警示
當交換器連線失敗超過設定 的錯誤 或 嚴重 性閾值時,即會觸發 RAP208 自動修復工作流程。一旦超過此閾值,xDoctor 就會產生 RAP208 警示,作為自動化修復程序的觸發器。
警示輸出範例
注意:在 ECS xDoctor v4.8-109.0 和 ObjectScale xDoctor v5.1-109.0 之前的 xDoctor 版本中,此狀況僅會導致警示。不執行自動補救。

自動修復程式補救 (範例)
啟用自動修復程式後,xDoctor 會套用本知識庫中概述的常見修正措施,自動針對偵測到的交換器連線問題啟動補救。

自動修復器要求
必須啟用 xDoctor 自動修復功能,才能進行此補救。自動修復程式可在安裝期間或安裝後依照下列步驟啟用:
原因
更換交換器後,用於驗證交換器的 SSH 主機金鑰可能會變更,或是連接至交換器的管理介面可能會以系統管理方式關機。有時,在 xDoctor 中配置的密碼與受影響交換器上的當前密碼不匹配,必須相應地進行更新。
xDoctor 自動化和自動修復工作流程 不會執行交換器密碼補救。相反地,xDoctor 會偵測與驗證相關的故障,並發出適當的警示,將使用者引導至相關知識文章,說明如何配置 xDoctor 以使用在交換器上設定的密碼。
解析度
xDoctor 自動修復器:ObjectScale xDoctor v5.1-109.0 / ECS xDoctor v4.8-109.0 或更新版本
- 若要手動觸發已啟用的自動修復程式,請在
master.rack節點。這將啟動機架分析器,一次一個地驗證和自動修復節點。
