從Cisco交換器移轉至Cisco Nexus 2300YC交換器
您可以將不中斷營運的舊Cisco叢集交換器移轉至ONTAP Cisco Nexus 92300YC叢集網路交換器、以供支援使用。
移轉完成後、您可能需要安裝所需的組態檔、以支援適用於92300YC叢集交換器的叢集交換器健全狀況監視器(CSHM)。請參閱"安裝叢集交換器健全狀況監視器(CSHM)"。 |
檢閱要求
-
完整功能的現有叢集。

移轉交換器
本程序中的範例使用下列交換器和節點命名法:
-
現有的Cisco Nexus 5596UP叢集交換器為C1和C2。
-
新的Nexus 2300YC叢集交換器為CS1和CS2。
-
節點是node1和node2。
-
叢集lIF分別是節點1上的node1_clus1和node1_clus2、以及節點2上的node2_clus1和node2_clus2。
-
交換器C2先由交換器CS2取代、然後由交換器CS1取代交換器C1。
-
將C1連接至CS1的CS1上建置了暫時ISL。
-
然後從C2中斷連接節點與C2之間的纜線、並重新連接至CS2。
-
然後、節點與C1之間的纜線會從C1中斷連線、然後重新連線至CS1。
-
然後移除C1與CS1之間的暫用ISL。
-
-
有些連接埠是在Nexus 2300YC交換器上設定、以10 GbE或40 GbE執行。
-
叢集交換器使用下列連接埠來連線至節點:
-
連接埠E1/1-48(10/25 GbE)、E1/49-64(40/100 GbE):Nexus 2300YC
-
連接埠E1/1-40(10 GbE):Nexus 5596UP
-
連接埠E1/1-32(10 GbE):Nexus 5020
-
連接埠E1/1-12、2/1-6(10 GbE):Nexus 5010、含擴充模組
-
-
叢集交換器使用下列交換器間連結(ISL)連接埠:
-
連接埠E1/65-66(100 GbE):Nexus 92300YC
-
連接埠E1/41至48(10 GbE):Nexus 5596UP
-
連接埠E1/33-40(10 GbE):Nexus 5020
-
連接埠E1/13-20(10 GbE):Nexus 5010
-
-
"交換器Hardware Universe" 包含所有叢集交換器支援的纜線連接資訊。
-
本程序所支援的支援的支援版本包括ONTAP "Cisco乙太網路交換器" 頁面。
步驟1:準備移轉

如果AutoSupport 此叢集啟用了「支援」功能、請叫用AutoSupport 下列訊息來禁止自動建立案例:
「系統節點AutoSupport 不完整地叫用節點*-type all -Message MAn=xh」
其中x是維護時段的持續時間(以小時為單位)。
此資訊可通知技術支援人員執行此維護工作、以便在維護期間抑制自動建立案例。AutoSupport 顯示範例
下列命令會禁止自動建立兩小時的個案:
