如何從Cisco交換器移轉至Cisco Nexus 9336C-FX2叢集交換器
貢獻者
您可以將不中斷營運的舊Cisco叢集交換器移轉至ONTAP Cisco Nexus 9336C-FX2叢集網路交換器、以利進行非中斷的叢集式叢集。
-
現有叢集必須正確設定並正常運作。
-
所有叢集連接埠都必須處於「up」狀態、以確保不中斷營運。
-
Nexus 9336C-FX2叢集交換器必須在適當版本的NX-OS安裝和套用參考組態檔（RCF）下進行設定和操作。
-
現有的叢集網路組態必須具備下列項目：
-
使用兩個舊Cisco交換器的備援且功能完整的NetApp叢集。
-
管理連線能力、以及對舊Cisco交換器和新交換器的主控台存取。
-
使用叢集生命區的所有叢集生命區都位於主連接埠上。
-
在舊的Cisco交換器之間以及新交換器之間啟用或連接ISL連接埠。
-
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 9336C-FX2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C2連接至CS2的CS2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。
-
接著移除C2與CS2之間的暫用ISL。
-
步驟
-
如果AutoSupport 此叢集啟用了「支援功能」、請叫用AutoSupport 「系統節點AutoSupport 支援功能叫用節點*-type all -most MAn=xh」訊息來禁止自動建立案例
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 -
將權限層級變更為進階、並在系統提示您繼續時輸入* y*：「et -priv家 特權進階」
出現進階提示（*>）。
-
驗證是否已在所有叢集lifs上啟用自動還原：「network interface show -vserver cluster -Fields auto-Revert」
cluster1::*> network interface show -vserver Cluster -fields auto-revert Logical Vserver Interface Auto-revert --------- ------------- ------------ Cluster node1_clus1 true node1_clus2 true node2_clus1 true node2_clus2 true 4 entries were displayed. -
判斷每個叢集介面的管理或作業狀態：
每個連接埠應顯示「Link」（連結）、「Health Status」（健全狀況狀態）則顯示為「Healthy」（健全狀況）。
-
顯示網路連接埠屬性：「network port show -IPSpace Cluster（網路連接埠顯示-IPSpace叢集）」
cluster1::*> network port show -ipspace Cluster Node: node1 Ignore Speed(Mbps) Health Health Port IPspace Broadcast Domain Link MTU Admin/Oper Status Status --------- ------------ ---------------- ---- ---- ----------- -------- ------ e0a Cluster Cluster up 9000 auto/10000 healthy false e0b Cluster Cluster up 9000 auto/10000 healthy false Node: node2 Ignore Speed(Mbps) Health Health Port IPspace Broadcast Domain Link MTU Admin/Oper Status Status --------- ------------ ---------------- ---- ---- ----------- -------- ------ e0a Cluster Cluster up 9000 auto/10000 healthy false e0b Cluster Cluster up 9000 auto/10000 healthy false 4 entries were displayed. -
顯示有關邏輯介面及其指定主節點的資訊：「network interface show -vserver Cluster」（網路介面show -vserver叢集）
每個LIF都應顯示為「狀態管理/作業者」、而「IS主頁」則顯示為「真」。
cluster1::*> network interface show -vserver Cluster Logical Status Network Current Current Is Vserver Interface Admin/Oper Address/Mask Node Port Home ----------- ----------- ---------- ------------------ ------------- ------- ---- Cluster node1_clus1 up/up 169.254.209.69/16 node1 e0a true node1_clus2 up/up 169.254.49.125/16 node1 e0b true node2_clus1 up/up 169.254.47.194/16 node2 e0a true node2_clus2 up/up 169.254.19.183/16 node2 e0b true 4 entries were displayed. -
-
每個節點上的叢集連接埠都會以下列方式（從節點的角度）連接至現有的叢集交換器：「network device-dDiscovery show -protocol cup」（網路裝置探索show -protocol cup）
