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。
背景資訊
無中斷升級概述
此過程適用於開放系統和FICON MDS交換機。
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所限制。請參閱MDS文檔，包括發行說明: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。可以找到開放系統和FICON的無中斷升級表：Cisco MDS 9000 NX-OS軟體和韌體升級和降級指南9.x版。
這些版本已經過修改，需要從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，首次升級到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。代碼載入到以前處於活動狀態的Supervisor上，並成為新的備用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，請確保您已通過乙太網連線到兩個管理引擎。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，並且必須連線到上一個備用Supervisor。
同一交換矩陣中的多台交換機可以同時升級。升級交換矩陣中的所有交換機後，可以在大約七天的時間週期內評估所有裝置的功能。如果未發現任何問題，則可以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。在運行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。最終目標版本是期望的最終版本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。此過程可以重複用於每個中間目標版本和最終目標版本。
附註：驗證到最終目標版本的支援無中斷升級或降級路徑。可以在Cisco MDS 9000 NX-OS軟體和韌體升級和降級指南9.x版中「支援的Cisco MDS NX-OS軟體無中斷降級路徑」一章中找到。
1.將Show Tech-Support Detail的副本另存為Gzip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異常，則使用升級前交換機的狀態有助於進行故障排除，並減少診斷任何問題的時間。在NX-OS版本8.4(2b)和更新版本中，可以使用tac-pac命令。在之前的版本中，可以使用show tech-support details命令：
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
將您儲存的tac-pac/techsupport複製到TFTP伺服器，並將其重新命名為「before_install」。 這實現了三個目標：
- 它驗證您的TFTP伺服器是否工作正常。
- 它驗證您是否可以通過IP網路訪問伺服器。
- 它將配置的副本放在交換機外部的位置，這樣您就可以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：在上一個使用TFTP的範例中，MDS也支援FTP、SCP和SFTP。
3.（可選）將當前映像儲存在交換機外部的使用中
確認您的TFTP伺服器上存在目前映像的副本，以便如果您必須回復到原始版本，您就有備份。如果不這樣做，請立即將其從交換器複製到TFTP伺服器。要確定當前映像，請運行show version命令。請參見以下示例：
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：對於提示檔名條目，請使用當前版本。
在上一個範例中，使用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)，版本面向美國商務部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。
下表可用於選擇您的交換器系列和交換器軟體映像：

檔名以m9700-sf4ek9開頭 |
附註：在思科下載頁面上，將滑鼠懸停在檔名上以檢索消息摘要5(MD5)。
5.驗證Bootflash上是否有足夠的可用空間用於新增新映像
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，如果發生故障，您可以將交換機轉到可載入(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。
運行dir命令檢查可用的bootflash可用空間：
MDS9124V# dir bootflash:
如果運行雙Supervisor MDS 9700交換機，請運行以下命令檢查備用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：在上一個範例中，使用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
bios: v1.11.0(11/27/2024)
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，必須重新下載。
MDS9124V# show version image m9124v-s8ek9-mz.9.4.3a.bin
MD5 Verification Failed
Image integrity check failed
如果要升級的MDS是9700系列，請將kickstart和系統映像複製到備用supervisor上的bootflash:
mds-9706# copy bootflash:m9700-sf4ek9-kickstart-mz.9.4.4.bin bootflash://sup-standby/ Copy progress 100% 80165KB Copy complete, now saving to disk (please wait)... mds-9706# copy bootflash:m9700-sf4ek9-mz.9.4.4.bin bootflash://sup-standby/ Copy progress 100% 542544KB Copy complete, now saving to disk (please wait)... mds-9706#
7.保存SAN分析配置並暫時禁用SAN分析功能
如果所有步驟都為true，則必須完成此步驟：
- 已啟用SAN分析。
- 該交換機型號為MDS 9700交換機，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機型為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個升級時，此步驟只能在第一個NX-OS升級中完成。
這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，第15步重新啟用分析。如果show feature命令顯示分析功能已禁用，則可以跳過此步驟和步驟14。此問題已記錄在Cisco錯誤ID CSCwo03706.
此命令顯示插槽12中的32 Gbps模組是MDS 9718:

如果交換機型號是MDS 9700交換機，則必須完成此步驟。
從活動Supervisor運行系統switchover命令。系統切換完成後，重新連線新啟用的Supervisor，並等待待命Supervisor達到「ha-standby」狀態。
以下是從作用中Supervisor上的主控台連線執行system switchover指令的範例：

9.檢查NX-OS版本之間的不相容性
運行show incompatibility system <target system image name>命令，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。這還可以確保/var/volatile/tmp檔案系統有足夠的空間繼續運行。範例如下：
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
這將檢查映像並確保它們與交換機相容。它還指示映像中是否包含BIOS升級。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，而不是兩行單獨輸入。此命令不用於安裝，但是它可用於驗證安裝過程並提供顯示來往版本的報告。在執行升級時，此命令還會顯示升級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，從而阻止進行升級。
附註：32 Gbps交換矩陣交換機的具體准則：
- 從NX-OS 9.4(5)開始，升級到任何更高版本的NX-OS時，在32 Gbps交換矩陣交換機上啟用Supervisor CPU BIOS更新的機制已改變。預設情況下，BIOS更新是安裝的，但除非交換機被中斷地重新載入，否則CPU不會載入更新。ISSU install all命令已通過disrsible選項進行了增強，以允許在ISSU結束時自動執行中斷性重新載入。或者，中斷性重新載入可以在ISSU之後完成，作為以後使用reload命令進行的單獨操作。請勿使用reload system non-disruptive命令。要確定升級是否也包含BIOS升級，請檢查show install all impact命令的輸出。
- 對於運行低於NX-OS 9.4(5)版本的NX-OS的32 Gbps交換矩陣交換機，在ISSU期間啟用Supervisor CPU BIOS的機制不可靠。只有在新NX-OS版本包含BIOS更新時，才可以在升級之前使用hidden install module 1 bios system newNxosSystemImage 命令安裝新NX-OS中的BIOS。然後，可以使用reload CLI命令以中斷方式重新載入交換機。不要使用reload system non-disruptive命令。隨後，NX-OS的ISSU可以無中斷地執行，因為ISSU可以檢測到BIOS已經升級。
- 如需詳細資訊，請參閱步驟12和14。
附註：針對64 Gbps交換矩陣交換機的具體指南：
在64 Gbps交換矩陣交換機上啟用BIOS更新的機制已更改。首次升級到NX-OS 9.4(5)或更高版本後，建議同時升級交換機EPLD。此EPLD包含新功能，允許交換機的CPU獨立重新通電，同時仍保持無中斷流量轉發。由於交換機作為EPLD升級的一部分重新載入，因此所有EPLD升級都會中斷。第一次升級到NX-OS 9.4(5)或更高版本後，必須完成一次。
如需詳細資訊，請參閱步驟14。
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。運行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：上一個示例顯示檔案系統已使用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Supervisor BIOS
每種特定型別的硬體都有自己的BIOS版本。編號會因特定硬體型別（如管理引擎、交換模組等）而大不相同。如果步驟10中show install all impact命令的輸出表明目標版本中存在BIOS升級，請繼續執行以下步驟。
附註：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，此過程適用於所有交換機型號。它還適用於運行低於NX-OS 9.4(5)的NX-OS版本的32 Gbps交換矩陣交換機。 繼續這些步驟之前，請確保已將NX-OS映像複製到Supervisor。
- 在運行hidden命令的每個supervisor上手動安裝最新的supervisor BIOS:安裝模塊module_number bios system newNxosSystemImage。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。對於MDS交換矩陣交換機，模組編號始終為1。在交換矩陣交換機上，可以在BIOS升級完成後重新載入交換機。這可透過reload指令完成。在本示例中，從MDS 9124V交換矩陣交換機上的9.4(3a)系統映像升級BIOS:
MDS9124V# install module 1 bios system m9124v-s8ek9-mz.9.4.3a.bin

14.重新載入或安裝EPLD for Fabric Switch
- 32 Gbps交換矩陣交換機的具體准則：
如果升級是在NX-OS 9.4(5)或更高版本之後且包含BIOS升級，則重新載入運行reload CLI命令的交換機。請勿運行reload system non-disruptive命令。
- 針對64 Gbps交換矩陣交換機的具體指南：
在64 Gbps交換矩陣交換機上啟用BIOS更新的機制已更改。新機制要求一次性中斷交換機EPLD升級到IO FPGA版本或更高版本：
用於無中斷BIOS更新的表IO FPGA版本：
| 交換器 | 最低IO FPGA版本(IO SPI 2) |
| MDS 9124V | 0.018 |
| MDS 9148V | 0.018 |
| MDS 9396V | 0.016 |
這些版本作為NX-OS 9.4(5)的一部分發佈，可以在交換機運行NX-OS 9.4(5)（或更高版本）後安裝。 運行install module 1 epld CLI命令升級了EPLD。這包括自動中斷地重新載入交換機以啟用EPLD更新。如果EPLD未升級，則使用舊重新載入機制，這可能導致交換機在ISSU期間掛起，這包括BIOS更新。16 Gbps和32 Gbps交換矩陣交換機上不存在此功能。
更新EPLD後，後續的ISSU可以啟用映像中包含的任何新BIOS版本，而不會中斷重新載入。要確定當前EPLD版本，請運行show version module 1 epld命令。EPLD裝置「IO SPI 2」是必須與上表匹配的版本。
以下來自MDS 9148V交換機的示例，顯示「IO SPI 2」版本為0.013，低於所需的0.018版本：
MDS9148V# show version module 1 epld
EPLD Device Version
---------------------------------------
MI IO SPI 0.011
IO SPI 2 0.013
有關EPLD安裝和更新的詳細資訊，請參閱MDS 9000系列EPLD韌體版本9.4(5)的發行說明，其中包含所有MDS文檔。
15.驗證安裝。
通過運行show version命令並注意系統和kickstart版本是預期版本，驗證安裝是否成功和完成：
