Cause

這些警示會在 PowerStore 複製工作階段遺失時產生,這些警示可能會快速復原,但會針對暫時中斷連線建立警示。如果這些事件很快復原,這可能不是問題,儘管這是網路問題的症狀。

Resolution

PowerStoreOS 4.0 預期會降低警示的頻率,儘管事件可能仍會發生。

因應措施:
如果您認為您的問題與本文所述問題相符,請聯絡 PowerStore 的 Dell 技術支援 部門,並參考本文。

作為可能的因應措施,建議在網路中為複寫連結實作 QoS。此建議取決於特定環境,不一定會減少出現的警示數量。還建議您確定遠端連線網路延遲設定為「高」。它位於遠端連接屬性下。

一些其他資訊可協助確認問題是否符合本文中的內容:

  • 複製是否通過 WAN 或 LAN 運行?
  • WAN 或 LAN 是專用的還是共用的?
  • WAN 或 LAN 的連結大小或速度是多少?
  • 是否還有其他系統或應用程式在同一時間範圍內回報連線問題?
