在HA中更換Catalyst 9000的Supervisor模組或堆疊成員
目錄
簡介
本文說明如何在HA（高可用性）設定中替換Catalyst 9K交換器的監督器模組或堆疊成員。
必要條件
需求
思科建議您熟悉Catalyst 9K交換器上的堆疊、stackwise-virtual(SVL)和「套件組合」與「安裝」開機模式相關概念。
採用元件
本文中的資訊係根據以下軟體和硬體版本：
- C9200
- C9300
- C9400
- C9500
- C9600
本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路運作中，請確保您瞭解任何指令可能造成的影響。
背景資訊
本文包括替換堆疊式交換機型別成員的過程：
- C9200/C9300堆疊成員
- 使用SVL的C9500
- C9400/C9600機箱在其各種操作模式（獨立、雙支援、SVL和四支援SVL）下的管理引擎。
更換C9300或C9200堆疊的成員
在本範例中，您會替換C9300堆疊的成員。（本示例中的交換機在「安裝」引導模式下使用switch 2）。
驗證更換前
檢查當前堆疊狀態並準備進行交換。確保將交換機上的boot變數設定為指向正確的程式包文件（如果啟動模式為「安裝」）或bin檔案（捆綁包啟動模式），並啟用auto-boot功能。

Manual Boot = no

iPXE Timeout = 0
C9300#show run all | in software auto
no software auto-upgrade source url
software auto-upgrade enable
檢查堆疊是否以全環形連線，例如，如果關閉相關交換器成員的電源，則不會分割現有堆疊而導致堆疊合並。驗證後，請轉到後續步驟。

替換
關閉需要更換的成員交換機的電源，斷開與其的電源堆疊和資料堆疊電纜。在電源關閉狀態下，將成員更換為新成員，重新連線資料堆疊電纜並開機。
如果堆疊處於「套件組合」開機模式，請在啟動時進入新交換器的ROMMON。藉助USB盤或OOB TFTP訪問，使用與現有堆疊相同的軟體版本手動引導新交換機。

rommon 1 >
rommon 2 > boot usbflash0:cat9k_iosxe.17.03.01.SPA.bin
如果堆疊處於「安裝」開機模式下，則在檢測到新成員交換器上的軟體版本或開機模式不相容時，必須啟動堆疊的當前作用中自動軟體升級。通常，此階段不需要手動干預。

更換C9400獨立機箱的冗餘管理引擎
在本示例中，您將更換C9404機箱的Active Supervisor。（本示例中的交換機在「安裝」引導模式下用於插槽3。）
驗證更換前
檢查交換器上的開機變數是否設定為指向正確的套件檔案（如果開機模式為安裝）或bin檔案（套件組合開機模式），且自動開機已啟用。

如果需要替換主用Supervisor(如本例中的示例中)，請對備用管理引擎執行故障轉移，並等待它接管主用角色。如果要替換備用管理引擎，請跳過此步驟。

替換
從機箱中移除有故障的Supervisor，插入新的有控制檯電纜的Supervisor。
如果活動Supervisor在「捆綁」引導模式下運行，則在新Supervisor啟動時，請將其中斷到新Supervisor的ROMMON。藉助USB介面或OOB TFTP訪問，使用與您的活動Supervisor相同的軟體版本手動引導Supervisor。

更換C9400 Dual-Sup StackWise-Virtual管理引擎
此示例適用於C9400 stackwise虛擬設定（每個機箱中有一個管理引擎），其中機箱1的管理引擎（活動交換機）已損壞，需要更換。SVL正在以「安裝」引導模式運行。
驗證更換前
檢查當前與StackWise-Virtual相關的配置和主管狀態。確保交換機上的啟動變數設定正確，指向正確的程式包檔案（如果啟動模式為「安裝」）或bin檔案（捆綁包啟動模式），並且已啟用自動啟動。

替換
關閉需要更換管理引擎的機箱的電源（在我們的示例中，它是chassis-1）。
從各個機箱的背板中卸下線卡（需要更換管理引擎）。 無需將線卡完全從機箱中取出，只要它們沒有連線到背板即可。這樣，當插入新的管理引擎並進行預轉移時，連線的遠端交換機（多機箱etherchannel）不會將其本地埠置於err-disabled狀態（LACP等）。

將新的Supervisor插入存在故障Supervisor的同一插槽並接通電源。它必須在單機模式（非SVL）下啟動，暫時斷開Stackwise虛擬鏈路連線。
- 如果作用中Supervisor在「套件組合」開機模式下執行，請將軟體bin檔案（與SVL的目前作用中Supervisor相同）複製到新待命Supervisor的bootflash中，並相應地變更開機字串。
- 如果您的活動Supervisor在「安裝」引導模式下運行，則不需要手動軟體升級。如果新的/待命Supervisor檢測到不相容的軟體版本或引導模式，則必須由當前活動Supervisor自動升級新Supervisor的軟體和引導模式。
使用Stackwise虛擬設定配置新主管。（必須使用相同的SVL域號來匹配現有成員。）

儲存配置並關閉新管理引擎所在的機箱的電源。
連線兩個機箱之間的StackWise-Virtual鏈路，並希望斷開雙活動檢測鏈路（如果適用）。
開啟機箱電源，通過控制檯監控引導過程。
- 如果您的SVL在「捆綁包」引導模式下運行，請確保新的Supervisor提供的軟體版本與活動版本相同。如果沒有，請重新進入ROMMON並使用正確的軟體版本手動啟動。
- 如果SVL在「安裝」引導模式下運行，則「軟體自動升級」必須負責將正確的軟體版本和引導模式推送到新Supervisor中，無需任何手動干預。

更換C9500 StackWise-Virtual的成員
在本例中，您考慮將Switch-1（活動交換機）的C9500 Stackwise虛擬設定作為需要更換的故障交換機。SVL正在安裝引導模式下運行。
驗證更換前
檢查目前的StackWise-Virtual相關組態和交換器的狀態。請確保正確設定了引導變數，指向packages.conf ，且配置暫存器設定為0x2102。

更換C9600 Dual-Sup StackWise-Virtual管理引擎
在本示例中，您考慮的是C9600 stackwise虛擬設定（每個機箱一個管理引擎），其中機箱1的管理引擎（活動交換機）已損壞，需要更換。SVL正在以「安裝」引導模式運行。
驗證更換前
檢查當前與StackWise-Virtual相關的配置和主管狀態。確保交換機上的啟動變數設定正確，指向正確的程式包檔案（如果啟動模式為「安裝」）或bin檔案（捆綁包啟動模式），並且已啟用自動啟動。

- 如果需要替換活動Supervisor(如我們的示例中)，請執行到待命Supervisor的故障轉移，並等待備用Supervisor接管活動角色。如果要替換備用Supervisor，請跳過此步驟。

替換
關閉需要更換管理引擎的機箱的電源。在我們的示例中，它是chassis-1。
從各自機箱的背板中卸下線卡（需要更換管理引擎），StackWise虛擬鏈路(SVL)所連線的線卡除外。對於配置了SVL的線卡，請刪除除SVL本身以外的所有連線。這樣，當插入新的管理引擎並進行預轉移時，連線的遠端交換機（多機箱etherchannel）不會將其本地埠置於err-disabled狀態（LACP等）。

將新的Supervisor插入存在故障Supervisor的同一插槽並接通電源。它必須在單機模式（非SVL）下啟動，暫時保持Stackwise虛擬連結和DAD連結斷開連線。
如果作用中Supervisor在「套件組合」開機模式下執行，請將軟體bin檔案（與SVL的目前作用中Supervisor相同）複製到新待命Supervisor的bootflash中，並相應地變更bootstring。
如果您的活動Supervisor在「安裝」引導模式下運行，則不需要手動軟體升級。如果新的/待命Supervisor檢測到不相容的軟體版本或引導模式，則必須由當前活動Supervisor自動升級新Supervisor的軟體和引導模式。
使用Stackwise虛擬設定配置新主管。（必須使用相同的SVL域號來匹配現有成員）。

更換C9600 Quad-Sup StackWise-Virtual管理引擎
在本示例中，您考慮採用C9600 Quad Sup Stackwise虛擬機器設定（每個機箱中有兩個管理引擎），其中管理引擎已損壞，需要更換。SVL正在以「安裝」引導模式運行。
更換和驗證
拔出有故障的主管
- 如果要更換的Supervisor是Global Active Supervisor（圖中所示為Sw-1 Slot 3），請執行故障切換，以便全域性備用（圖中所示為Sw-2 Slot 3）接管Active。等待新的全域性備用並完成SSO。（在本例中，Sw-1插槽4將成為新的全域性備用插槽）。
- 如果要更換的Supervisor是Global Standby Supervisor（圖中所示為Sw-2插槽3），請將Supervisor拉出。等待新的全域性備用並完成SSO。（在本例中，Sw-2插槽4將成為新的全域性備用插槽）
- 如果要更換的Supervisor是ICS Supervisor（圖中所示的Sw-1 Slot 4或Sw-2 Slot 4），請拔出Supervisor。
插入新主管
- 如果新管理引擎運行的是17.x代碼,則這些步驟是直接向前執行的。只需插入新的管理引擎。如果ICS管理引擎具有17.x映像，它們將自動啟動並成為Quad-sup的一部分。即使它運行的17.x代碼與生產設定中正在運行的17.x代碼不同，軟體自動升級也會自動負責在安裝模式下使用相同的17.x代碼升級ICS監控器。
- 如果新Supervisor運行的是16.x代碼，或者您不確定它運行的代碼，請嘗試將Supervisor插入備用機箱中，然後將其升級到17.x代碼。如果沒有要升級的備用機箱，則必須採取這些步驟。
- 此步驟非常重要。插入ICS管理引擎並使用Ctrl+C將其中斷為rommon。如果您無法進入ROMMON模式，且主管在16.x代碼上啟動，則可能會拆下插入主管的整個機箱
查詢任何與SVL相關的rommon變數。這些變數以D_STACK開頭。通常新主管沒有設定這些變數。
D_STACK_DISTR_STACK_LINK2=""
D_STACK_DAD="Fo1/0/13,Fo1/0/15,"
D_STACK_MODE="aggregation"
D_STACK_DOMAIN_NUM="255"
D_STACK_DISTR_STACK_LINK1="Fo1/0/10,Fo1/0/15,Fo1/0/16,Fo1/0/17,Fo1/0/3,Fo1/0/6,"
取消設置先前顯示的所有變數
rommon 1 > unset D_STACK_DAD
rommon 1 > unset D_STACK_DISTR_STACK_LINK1
rommon 1 > unset D_STACK_DOMAIN_NUM rommon 1 > unset D_STACK_MODE
尋找變數「SWITCH_NUMBER=1」。 如果交換機編號為2，則將變數設定為1。如果變數已經為1，請轉至下一步。
rommon 1 > SWITCH_NUMBER=1
設定為手動啟動Supervisor。
rommon 1 > MANUAL_BOOT=YES
使用USB/TFTP在17.x代碼上手動引導套件組合模式中的ICS監控器。請勿在rommon中更改引導變數。只需從rommon手動啟動。
- 當Supervisor在SVL模式中檢測現有ICS時，它會重置，因此它從獨立模式轉換到stackwise虛擬模式。由於自動引導被禁用，它可能會再次回到rommon中。
取消設置手動引導以啟用自動引導。
rommon 1 > unset MANUAL_BOOT
使用USB/TFTP在17.x代碼上手動引導套件組合模式中的ICS監控器。請勿在rommon中更改引導變數。只需從rommon手動啟動。此步驟在套件組合模式下啟動ICS。
