Symptoms


在託管於 PowerFlex 儲存裝置的 Windows 2012 R2 VM 上執行的 PowerFlex SDC 驅動程式載入緩慢,最後掛起,且無法存取對應至它的磁碟區。

症狀
從 Windows SDC 執行 ping 命令至其中一個 SDS 節點時無法成功完成。
登入 Windows 伺服器的系統事件會顯示如下磁碟問題。

影響
主機變得緩慢且沒有回應。無法存取 SDC 指派的磁碟區。

Cause

已對環境中的防火牆規則進行變更。一個 SDS 節點不在防火牆規則集中,導致 SDC 失去對指定卷的訪問許可權。

 

Resolution

重新獲得卷訪問許可權的最快方法是將防火牆 SDS 置於維護模式。這僅適用於只有一個故障組受到影響的情況 (一般維護模式規則適用)

修正防火牆規則,將 PowerFlex SDS 節點新增回規則中。確保埠 7072 已打開且未被任何其他應用程式使用。

使用 ping/telnet 測試以確認已套用防火牆規則,而且將 SDS 退出維護模式是安全的。
