如果您在與整合Hyperflex群集的vCenter中看到「NFS all paths down」錯誤消息,則本文檔為您提供了可執行的快速瞭解和故障排除步驟,以便評估問題的根源。
vCenter中的典型錯誤消息如下。
在主機上看到APD警報後,獲取以下資訊以更好地瞭解問題說明:
為了對APD進行故障排除,我們需要瞭解3個元件 — vCenter、SCVM和ESXi主機。
這些步驟是建議的工作流程,旨在查明或縮小出現的所有路徑關閉症狀的來源。請注意,此訂單不必嚴格遵守,您可以根據在客戶環境中觀察到的特定症狀來充分遵循此訂單。
連線到vCenter Server(VCS)並導航到受影響的主機
連線到所有StCtlVM並驗證下面的指標,您可以使用 MobaXterm 軟體的路由器之間的 CLI 設定站點對站點(LAN 對 LAN)IPSec 網際網路金鑰交換版本 1 (IKEv1) 通道。
