執行MDS 9000系列交換機無中斷NX-OS升級
簡介
本文檔介紹在Cisco MDS 9000系列多層導向器交換機(MDS)上無中斷升級NX-OS軟體的說明。此過程適用於開放系統和FICON MDS交換機。
背景資訊
無中斷升級概述
所有MDS交換機均支援無中斷升級和降級，這受Cisco MDS 9000 NX-OS和SAN-OS軟體安裝和升級指南中列出的限制限制。所有MDS文檔（包括發行說明）都可以在以下位置找到：Cisco MDS 9000 - 9.x版文檔套件。
目標版本是在安裝全部步驟中升級或降級到MDS的NX-OS版本。最終目標版本是所需的最終版本NX-OS版本。可能需要安裝兩個或多個這些中間目標版本，才能達到最終目標版本。以下提供了開放系統和FICON的無中斷升級清單：Cisco MDS 9000 NX-OS軟體和韌體升級和降級指南9.x版本。這些已修改為要求從9.4(1a)之前的NX-OS版本升級到9.4(1a)之後的最終目標NX-OS版本的所有升級都必須首先升級到NX-OS 9.4(1a)。 必須參閱Cisco MDS 9000 NX-OS軟體和韌體升級和降級指南瞭解詳細資訊。
在具有雙管理引擎的97xx系列MDS上，在NX-OS安裝期間，新映像載入到備用管理引擎上。然後進行切換，以使運行新代碼的備用Supervisor處於活動狀態。然後，代碼載入到以前處於活動狀態的Supervisor上，它成為新的備用Supervisor。資料平面繼續通過光纖通道流量。然後，這些模組以無中斷方式從編號最低的模組開始升級過程，並繼續執行最高過程。
MDS 91xx、92xx或93xx系列交換矩陣交換機只有一個管理引擎。升級完成後，將以無中斷方式重新載入Supervisor（控制平面）。資料平面繼續無中斷地通過光纖通道流量。
如果您打算通過Telnet、安全殼層(SSH)或簡單網路管理協定(SNMP)（交換矩陣管理器/裝置管理器）進行升級，請確保您已與兩個管理引擎建立乙太網連線。當Supervisor以無中斷方式重新啟動時，您的終端會話將丟失。 您必須重新連線到交換機。您現在連線到上一個備用管理引擎。
同一交換矩陣內的多個交換機可以同時升級。一旦交換矩陣中的所有交換機都已升級，則應在大約7天的時間內評估所有裝置的功能。如果未發現任何問題，則可能會更新冗餘交換矩陣中的交換機。
更新的MDS升級說明 — 適用於所有MDS平台
升級MDS 9000系列交換機的最佳實踐已經更新，以確保順利使用ISSU。在發出install all kickstart之前…… 系統……指令，請嚴格遵循此步驟。
附註：目標版本是在安裝全部步驟中升級或降級到MDS的NX-OS版本。最終目標版本是所需的最終版本NX-OS版本。可能需要安裝兩個或多個這些中間目標版本才能到達最終目標版本。對每個中間目標版本和最終目標版本應重復此過程。
附註：驗證受支援的無中斷升級或降級路徑到最終目標版本。可以在Cisco MDS 9000 NX-OS軟體和韌體升級和降級指南9.x版中的受支援的Cisco MDS NX-OS軟體無中斷降級路徑(Supported Cisco MDS NX-OS Software Nondisrupgrade Paths)一章中找到：
1.將Show Tech-Support Detail的副本另存為gzipped檔案。
其中包含當前交換機配置、日誌檔案和所有介面的狀態。如果在升級期間或升級後出現問題，在升級前保持交換機的狀態有助於進行故障排除，並縮短診斷問題的時間。在NX-OS版本8.4(2b)和更新版本中，可以使用tac-pac命令。在應該使用show tech-support details命令之前的版本中。
mds9124V# tac-pac
Collecting show tech-support details...
Show tech details will take 4-8 minutes to complete. Please Wait ...
Collecting show logging onboard...
tacpac file volatile:mds9124V_tacpac_2025-08-22.gz created.
mds9124V#
2.將tac-pac/techsupport檔案儲存到交換機外部。
將您剛剛儲存的tac-pac/techsupport複製到TFTP伺服器，將其重新命名為「before_install」。 這實現了三個目標：它會驗證您有一台可運行的TFTP伺服器，驗證您是否可以通過IP網路訪問該伺服器，並將配置副本放在交換機外部的位置，以便在交換機出現故障時進行備份。
MDS9124V# move volatile:F241-16-10-9124V-3_tacpac_2025-08-22.gz volatile:F241-16-10-9124V-3_tacpac_2025-08-22_before_install.gz
MDS9124V# copy volatile: tftp:
<prompts for file name> mds9124V_tacpac_2025-08-22_before_install.gz
<prompts for tftp server name or ip address> 192.168.1.1
附註：在上面的範例中使用的是tftp。MDS還支援ftp、scp和sftp。
3.（可選）儲存交換機外部正在使用的當前映像。
確認您的TFTP伺服器上是否有目前映像的副本，以便在必須返回原始版本的情況下進行備份。如果不這樣做，請在此時將其從交換器複製到TFTP伺服器。要確定當前映像，請發出show version命令。以下是一些範例：
MDS9124V# copy bootflash: tftp:
<prompts for file name> m9124v-s8ek9-kickstart-mz.9.3.2a.bin
<prompt for tftp server name or ip address> 192.168.1.1
MDS9148V# copy bootflash: tftp:
<prompts for file name> m9124v-s8ek9-mz.9.3.2a.bin
<prompt for tftp server name or ip address> 192.168.1.1
附註：對於條prompts for file name目，請使用當前實際版本。
附註：在上面的範例中使用的是tftp。MDS還支援ftp、scp和sftp。
4.下載目標系統和kickstart映像。
從思科下載軟體頁面下載新NX-OS映像。您既需要啟動映像，也需要系統映像。將其放在TFTP伺服器上的預設TFTP目錄中。
思科提供兩種型別的NX-OS軟體。Payload Non-Crypto，也稱為Non-Payload Encryption(NPE)，版本適用於美國商務部已列為包含加密的非出口軟體清單的國家或政府。NPE版本不包括某些高級故障排除功能。NPE版本還會限制思科提供變通方法或熱修復的能力。只有符合匯出限制的客戶才能運行NPE版本。

附註：在思科下載頁面上，將滑鼠懸停檔名以獲得消息摘要5(MD5)
5.驗證bootflash上是否有足夠的可用空間，以便新增新映像。
如果bootflash上的空間不足，無法容納目標系統和啟動映像，則必須至少擦除系統映像檔案。保留kickstart映像，以便在出現故障時使交換機到達可以載入(TFTP)新映像的位置。升級後，您可以刪除舊版本。附註：無法刪除當前映像。
輸入 dir命令以檢查bootflash可用空間：
MDS9124V# dir bootflash:
此外，如果運行雙Supervisor MDS 9700交換機，請輸入以下命令以檢查備用Supervisor上是否有足夠的可用空間：
MDS9700# dir bootflash://sup-standby/
6.從TFTP伺服器將新映像下載到交換機上的bootflash。
MDS9124V# copy tftp: bootflash:
<prompts for file name> m9124v-s8ek9-kickstart-mz.9.4.3a.bin
<prompt for tftp server name or ip address> 192.168.1.1
MDS9124V# copy tftp: bootflash:
<prompts for file name> m9124v-s8ek9-mz.9.4.3a.bin
<prompt for tftp server name or ip address> 192.168.1.1
附註：在上面的範例中使用的是tftp。MDS還支援ftp、scp和sftp。
驗證校驗和，以及MD5校驗和：
有效的MD5校驗和示例：
MDS9124V# show version image m9124v-s8ek9-mz.9.4.3a.bin
MD5 Verification Passed
image name: m9124v-s8ek9-mz.9.4.3a.bin

system: version 9.4(3a)
compiled: 3/1/2025 12:00:00 [03/25/2025 00:13:28]
MDS9124V#
無效的MD5校驗和示例，需要重新下載。
MDS9124V# show version image m9124v-s8ek9-mz.9.4.3a.bin
MD5 Verification Failed
Image integrity check failed
7.儲存SAN分析配置並暫時禁用SAN分析功能。
如果以下所有情況均為真，則必須執行此步驟：
- 已啟用SAN分析。
- 該交換機型號為MDS 9700交換機，它包含一個或多個32 Gbps模組「4/8/16/32 Gbps高級FC模組DS-X9648-1536K9」
對於IBM品牌9700交換機，「4/8/16/32 Gbps高級FC模組」的IBM機型是01FT644。
- 交換機型號為MDS 9132T、MDS 9148T或MDS 9396T。
當無中斷升級路徑包括到最終目標版本的多次升級時，此步驟只應在第一個NX-OS升級中完成。
這樣做是因為啟用分析並完成NX-OS升級時，可能會導致TCAM損壞的問題。升級完成後，將在步驟15中重新啟用分析。如果show feature命令顯示分析處於禁用狀態，則可跳過此步驟和步驟14。此問題已記錄在Cisco錯誤ID CSCwo03706 - FC介面不會啟動/切換到軟分割槽。
以下命令顯示32 Gbps模組位於MDS 9718的插槽12中：

如果交換機型號是MDS 9700交換機，則必須完成此步驟。
從作用中Supervisor發出system switchover命令。系統切換完成後，重新連線到新啟用的Supervisor，並等待待命Supervisor達到「ha-standby」狀態。
以下是從活動Supervisor上的控制檯連線發出的system switchover命令的示例：

9.檢查NX-OS版本之間的不相容性。
發出show incompatibility system <target system image name>命令，以檢查NX-OS版本之間的不相容性以及可能阻止升級的任何交換機事件。這也將確保/var/volatile/tmp檔案系統有足夠的空間繼續運行。以下是範例：
MDS9124V# show incompatibility system m9124v-s8ek9-mz.9.4.3a.bin
Checking incompatible configuration(s):
No incompatible configurations
Checking dynamic incompatibilities:
No incompatible configurations
MDS9124V#10.確定對安裝的任何影響。
這樣會檢查映像，並確保它們與交換機相容。這可透過show install all impact命令完成：
MDS9124V# show install all impact system m9124v-s8ek9-mz.9.4.3a.bin kickstart m9124v-s8ek9-kickstart-mz.9.4.3a.bin

附註：此命令必須輸入為一行，而不是兩行。此命令不用於安裝，但可用於驗證安裝過程並提供顯示來和去版本的報告。 在執行升級時，此升級還會顯示是中斷性還是非中斷性。
附註：開始升級/降級過程之前，必須關閉到交換機的所有檔案傳輸會話（如SFTP/SCP）。任何開啟的檔案傳輸會話都可能導致交換機在ISSU/D時中斷地重新載入。如需詳細資訊，請參閱Cisco錯誤ID CSCvo2269和Cisco錯誤ID CSCvu52058。 客戶端抱怨MobaXterm在開啟SSH會話時開啟SFTP會話，並且可能會阻止升級。
11.驗證tmp檔案目錄的使用率是否不超過9%。
有些MDS交換機使用/var/volatile/tmp目錄，而另一些交換機則使用/var/tmp目錄。使用show system internal flash | inc "/var/tmp|/var/volatile/tmp" 命令檢查以下兩個對象上的可用空間：
MDS9124V# show system internal flash | inc "/var/tmp|/var/volatile/tmp"
Mount-on 1K-blocks Used Available Use% Filesystem
/var/volatile/tmp 614400 104 614296 1 none
MDS9124V#
附註：上例顯示檔案系統僅使用了1% ，因此可以安全地繼續執行下一步。如果/var/volatile/tmp目錄或/var/tmp目錄的使用率超過9%，請不要繼續安裝，並與Cisco TAC聯絡。
12.從新系統映像升級BIOS。
每種特定型別的硬體都有自己的BIOS版本。編號因特定硬體型別（如管理引擎、交換模組等）而異。
在NX-OS 9.4(2)中引入了一個新的管理引擎BIOS，用於CVE-2024-20397。
當當前交換機NX-OS版本介於8.4(2)和9.3(2a)之間，而目標NX-OS版本為9.4(2)或更高時，此過程相關。繼續這些步驟之前，請確保已將NX-OS映像複製到Supervisor。使用隱藏命令在每個Supervisor上手動安裝最新的Supervisor BIOS。在具有雙管理引擎的MDS 9700上，必須在每個管理引擎上執行此操作。在本示例中，安裝了來自9.4(2a)的BIOS:
MDS9124V# install module 1 bios system m9124v-s8ek9-mz.9.4.3a.bin forced
