貢獻者
建議變更
PDF
您可以更換故障的Nexus 9336C-FX2共用交換器。這是不中斷營運的程序（NDU）。
您需要的產品
更換交換器之前、請確定：
-
在現有的叢集與網路基礎架構中：
-
現有的叢集已通過驗證、完全正常運作、至少有一個完全連接的叢集交換器。
-
所有叢集連接埠均為* up*。
-
所有叢集邏輯介面（l生命）都是* up *及其主連接埠。
-
使用支援Ping叢ONTAP 集的節點節點node1命令時、必須指出所有路徑上的基本連線能力和大於PMTU的通訊均已成功完成。
-
-
Nexus 9336C-FX2替換交換器：
-
替換交換器上的管理網路連線功能正常。
-
更換交換器的主控台存取已就緒。
-
節點連線為連接埠1/1至1/34：
-
所有交換器間連結（ISL）連接埠在連接埠1/35和1/36上都會停用。
-
所需的參考組態檔（RCF）和NX-OS作業系統映像交換器會載入交換器。
-
任何先前的站台自訂（例如STP、SNMP和SSH）都應該複製到新交換器。
-
關於範例
您必須執行命令、從裝載叢集LIF的節點移轉叢集LIF。
本程序中的範例使用下列交換器和節點命名法：
-
現有Nexus 9336C-FX2交換器的名稱為_SH1_和_sh2_。
-
新Nexus 9336C-FX2交換器的名稱為_newsh1_和_newsh2_。
-
節點名稱是_node1_和_node2_。
-
每個節點上的叢集連接埠名稱為_e3a_和_e3c_。
-
叢集LIF名稱為節點1的「node1_clus1」和「node1_clus2」、節點2的「node2_clus1」和「node2_clus2」。
-
對所有叢集節點進行變更的提示為cluster1：：*>。
下列程序以下列網路拓撲為基礎：

步驟
-
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）。
-
選用：在交換器newsh2上安裝適當的RCF和映像、並進行必要的站台準備。
-
如有必要、請針對新交換器驗證、下載及安裝適當版本的RCF和NX-OS軟體。如果您已確認新交換器已正確設定、而且不需要更新RCF和NX-OS軟體、請繼續執行 步驟3.。
-
請前往NetApp支援網站上的NetApp叢集與管理網路交換器參考組態檔案說明頁面。
-
按一下叢集網路與管理網路相容性對照表的連結、然後記下所需的交換器軟體版本。
-
按一下瀏覽器的返回箭號以返回「Description（說明）」頁面、按一下「Continue（繼續）」、「Accept the license agreement（接受授權合約）」、然後前往「Download（下載）」頁面。
-
請依照下載頁面上的步驟、針對ONTAP 您要安裝的版本的更新軟體、下載正確的RCF和NX-OS檔案。
-
-
[[step3]在新交換器上、以admin身分登入、並關閉所有連接至節點叢集介面的連接埠（連接埠1/1至1/34）。如果您要更換的交換器無法正常運作且已關機、請前往 步驟4.。叢集節點上的LIF應已容錯移轉至每個節點的其他叢集連接埠。

[[step7]從Nexus 9336C-FX2 sh2交換器拔下所有纜線、然後將其連接至Nexus C9336C-FX2 newsh2交換器上的相同連接埠。
-
在SH1和newsh2交換器之間啟動ISL連接埠1/35和1/36、然後驗證連接埠通道作業狀態。
連接埠通道應指示PO1（SU）、而成員連接埠應指示eth1/35（P）和eth1/36（P）。

[[step10]在上一步所用的同一個節點上、使用network interface revert命令、還原上一步與連接埠相關聯的叢集LIF。
在此範例中、如果Home值為true且連接埠為e3b、則節點1上的LIF node1_clus2會成功還原。
下列命令會將節點1上的LIF node1_clus2傳回主連接埠e3a、並顯示兩個節點上的LIF LIF相關資訊。如果兩個叢集介面的「Is Home」欄位都為* true*、而且顯示正確的連接埠指派、則啟動第一個節點會成功、在此範例中、節點1上的「是Home」欄位和「e3b」。
