VxRail 上的 VCF：無法存取 SDDC UI

Summary: SDDC UI 無法運作並開啟並顯示錯誤：- 「伺服器無法啟動。無法初始化 PSC 和/或 Postgres。請查看 SDDC Manager UI 伺服器記錄以取得更多詳細資料」 檢查後發現管理 VC 和工作負載網域 VC 之間的複寫已連同 EAM 服務的憑證續約一起修正。  但是，SDDC UI 仍無法存取。

Cause

節點上的主機金鑰可以基於各種原因進行更改，包括但不限於：

  • 從備份還原。
  • 手動重建
  • 手動干預以變更主機金鑰

由於此變更金鑰，SDDC Manager 無法透過 SSH 進入一或多個有問題的節點來執行嘗試的工作流程，因為預期的主機金鑰與節點顯示的金鑰不相符。

Resolution

使用「fix_known_hosts.sh」指令檔修正主機金鑰問題。
