Cause

在進一步調查時,可以看到以下行為:
每個 MMCS (MMCS-A 和 MMCS-B) 都可能在 128.221.252 (MMCS-A) 和 128.221.253 (MMCS-B) 網路上,在兩個 VPlex 叢集上 ping 所有導向器。
在這種情況下,(Cluster-1 和 Cluster-2) 上的 MMCS-B 無法 ping 128.221.253 網路上的遠端導向器,但本機導向器會從 128.221.253 網路上的兩個 MMCS-B ping「確定」。

無法透過 SSH 進入叢集 2 上的 MMCS-B....已取代叢集 2 上的 MMCS-B 以解決此問題。

 

Resolution

已更換 Cluster2 上的 MMCS-B 以解決此問題。
NDU 預先檢查現已清理乾淨,沒有錯誤。

 

Additional Information

重新整理 VS6 的 MMCS IP 資訊

Cluster-1 MMCS-A   128.221.252.33
Cluster-1 MMCS-B   128.221.253.33
Cluster-2 MMCS-A   128.221.252.65
Cluster-2 MMCS-B   128.221.253.65
