执行MDS 9000系列交换机无中断NX-OS升级
简介
本文档介绍在Cisco MDS 9000系列多层导向器交换机(MDS)上无中断升级NX-OS软件的说明。
背景信息
无中断升级概述
此过程适用于开放系统和FICON MDS交换机。
所有MDS交换机均支持无中断升级和降级，这受Cisco MDS 9000 NX-OS和SAN-OS软件安装和升级指南中列出的限制所限制。请参阅MDS文档，包括版本说明:Cisco MDS 9000 - 9.x版本文档套件。
目标版本是在安装全部步骤中将MDS升级或降级到的NX-OS版本。最终目标版本是所需的最终版本的NX-OS版本。可能需要安装两个或多个这些中间目标版本才能达到最终目标版本。可以找到开放系统和FICON的无中断升级矩阵：Cisco MDS 9000 NX-OS软件和固件升级和降级指南，版本9.x。
这些版本已经修改，需要从9.4(1a)之前的NX-OS版本升级到高于9.4(1a)的最终目标NX-OS版本，并首次升级到NX-OS 9.4(1a)。 必须参阅Cisco MDS 9000 NX-OS软件和固件升级和降级指南了解详细信息。
在具有双管理引擎的97xx系列MDS上，在NX-OS安装期间，新映像将加载到备用Supervisor上。然后进行切换，使运行新代码的备用Supervisor处于活动状态。代码加载到以前的主用Supervisor上，并成为新的备用Supervisor。数据平面继续通过光纤通道流量。然后，这些模块以无中断方式从编号最小的模块开始升级过程，并继续执行最高过程。
MDS 91xx、92xx或93xx系列交换矩阵交换机只有一个Supervisor。升级完成后，将以无中断方式重新加载管理引擎（控制平面）。数据平面继续在不中断的情况下传输光纤通道流量。
如果您打算通过Telnet、安全外壳(SSH)或简单网络管理协议(SNMP)（交换矩阵管理器/设备管理器）进行升级，请确保您已与两个管理引擎建立以太网连接。当Supervisor以无中断方式重新启动时，您的终端会话将丢失。您必须重新连接到交换机，并且必须连接到上一个备用Supervisor。
同一交换矩阵内的多个交换机可以同时升级。一旦交换矩阵中的所有交换机都升级，所有设备的功能都可在大约七天的时间内进行评估。如果未发现任何问题，则可以更新冗余交换矩阵中的交换机。
更新的MDS升级说明 — 适用于所有MDS平台
升级MDS 9000系列交换机的最佳实践已经更新，以确保使用ISSU时体验流畅。在运行install all kickstart之前…… 系统……命令，请严格遵循此步骤。
注意：目标版本是MDS在安装所有步骤中升级或降级到的NX-OS版本。最终目标版本是所需的最终版本NX-OS版本。可能需要安装两个或多个这些中间目标版本，才能达到最终目标版本。此过程可以重复用于每个中间目标版本和最终目标版本。
注意：验证支持到最终目标版本的无中断升级或降级路径。可以在Cisco MDS 9000 NX-OS软件和固件升级和降级指南9.x版中的支持Cisco MDS NX-OS软件无中断降级路径一章中找到该路径。
1.将Show Tech-Support Detail的副本另存为Gzipped文件
其中包含当前交换机配置、日志文件和所有接口的状态。如果在升级期间或升级之后出现异常，则了解升级之前的交换机状态有助于排除故障，并减少诊断任何问题的时间。在NX-OS版本8.4(2b)及更高版本中，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.将tac-pac/techsupport文件保存到交换机外部
将保存的tac-pac/techsupport复制到TFTP服务器，将其重命名为“before_install”。 这样可以实现以下三点：
- 它验证您是否有可操作的TFTP服务器。
- 它验证您是否可以通过IP网络访问服务器。
- 它将配置的副本放置在交换机的外部位置，因此您可以在交换机出现故障时进行备份。
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
注意：在上一个示例中使用TFTP，MDS还支持FTP、SCP和SFTP。
3.（可选）将当前映像保存在交换机的外部
验证您的TFTP服务器上有当前映像的副本，以便您具有备份（如果必须恢复为原始版本）。否则，请立即将其从交换机复制到TFTP服务器。要确定当前映像，请运行show version命令。请参阅以下示例：
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
注意：对于提示文件名条目，请使用当前版本。
在上一个示例中，使用TFTP。MDS还支持FTP、SCP和SFTP。
4.下载目标系统和启动映像
从思科下载软件页面下载新的NX-OS映像。您需要启动和系统映像。将它们放在TFTP服务器的默认TFTP目录中。
思科提供两种类型的NX-OS软件。Payload Non-Crypto，也称为Non-Payload Encryption(NPE)，版本适用于美国商务部列为包含加密的非出口软件列表的国家或政府。NPE版本中不包括某些高级故障排除功能。NPE版本还会限制思科提供变通方法或热修复的能力。只有符合出口限制的客户才能运行NPE版本。
下表可用于选择您的交换机系列和交换机软件映像：
| Cisco MDS系列交换机类型 | IBM MDS系列交换机类型 |
命名约定 |
| SAN24C-7 |
文件名以m9124v-s8ek9开头 |

|
| 02JD753 SF4 |
文件名以m9700-sf4ek9开头 |
注意：在思科下载页面上，将鼠标悬停在文件名上以检索消息摘要5(MD5)。
5.验证Bootflash上是否有足够的可用空间用于添加新映像
如果bootflash上的空间不足，无法容纳目标系统和启动映像，则必须至少擦除系统映像文件。保留kickstart映像，如果发生故障，您可以将交换机引导至可以加载(TFTP)新映像的位置。升级后，您可以删除旧版本。
注意：无法删除当前映像。
运行dir命令以检查可用的bootflash可用空间：
MDS9124V# dir bootflash:
如果运行双Supervisor MDS 9700交换机，请运行以下命令检查备用Supervisor上是否有足够的可用空间：
MDS9700# dir bootflash://sup-standby/
6.从TFTP服务器将新映像下载到交换机上的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
注意：在上一个示例中，使用TFTP。MDS还支持FTP、SCP和SFTP。
验证校验和，并验证MD5校验和：
有效的MD5校验和示例：
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#
无效的MD5校验和示例，必须重新下载。
MDS9124V# show version image m9124v-s8ek9-mz.9.4.3a.bin
MD5 Verification Failed
Image integrity check failed
如果要升级的MDS是9700系列，请将启动映像和系统映像复制到备用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分析配置并暂时禁用SAN分析功能
如果所有步骤都为true，则必须完成此步骤：
- 已启用SAN分析。
- 交换机型号为MDS 9700交换机，包含一个或多个32 Gbps模块“4/8/16/32 Gbps高级FC模块DS-X9648-1536K9”。
对于IBM品牌9700交换机，“4/8/16/32 Gbps高级FC模块”的IBM型号为01FT644。
- 交换机型号为MDS 9132T、MDS 9148T或MDS 9396T。
当无中断升级路径包括到最终目标版本的多个升级时，此步骤只能在第一个NX-OS升级时完成。
这是由于启用分析并完成NX-OS升级时，可能会导致TCAM损坏的问题。升级完成后，在第15步中重新启用分析。如果show feature命令显示分析已禁用，则可以跳过此步骤和步骤14。此问题记录在思科漏洞ID CSCwo03706中.
此命令显示插槽12中的32 Gbps模块是MDS 9718:

如果交换机型号是MDS 9700交换机，则必须完成此步骤。
从活动Supervisor运行system switchover命令。系统切换完成后，重新连接新激活的Supervisor，并等待备用Supervisor达到“ha-standby”状态。

9.检查NX-OS版本之间的不兼容
运行show incompatibility system <target system image name>命令检查NX-OS版本之间的不兼容性以及可能阻止升级的任何交换机事件。这还可以确保/var/volatile/tmp文件系统有足够的空间继续运行。以下是一个示例：
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.确定对安装的任何影响
这将检查映像并确保它们与交换机兼容。它还指示映像中是否包含BIOS升级。此操作通过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

注意：此命令必须作为单行输入，而不是作为两行输入。此命令不用于安装，但是，它可用于验证安装过程，并提供显示来自和即将到来的版本的报告。在执行升级时，它还会显示升级是中断性还是非中断性。
注意：在开始升级/降级过程之前，必须关闭到交换机的所有文件传输会话（如SFTP/SCP）。任何打开的文件传输会话都可能导致交换机在ISSU/D时中断地重新加载。
有关详细信息，请参阅Cisco Bug ID CSCvo2269和Cisco Bug ID CSCvu52058。客户端抱怨在打开SSH会话时MobaXterm会打开SFTP会话，从而阻止升级的发生。
注意：32 Gbps交换矩阵交换机的具体准则：
- 从NX-OS 9.4(5)开始，升级到任何更高的NX-OS版本时，激活32 Gbps交换矩阵交换机上的Supervisor CPU BIOS更新的机制已更改。默认情况下，BIOS更新是安装的，但是CPU不会加载，除非交换机被中断地重新加载。ISSU install all命令已通过disruptive选项得到增强，以允许在ISSU结束时自动执行中断性重新加载。或者，可以在ISSU之后使用reload命令完成中断性重新加载，作为以后单独的操作。请勿使用reload system non-disruptive命令。要确定升级是否也包含BIOS升级，请检查show install all impact命令的输出。
- 对于运行低于NX-OS 9.4(5)的NX-OS版本的32 Gbps交换矩阵交换机，在ISSU期间激活Supervisor CPU BIOS的机制不可靠。仅当新的NX-OS版本包含BIOS更新时，才能在升级之前使用hidden install module 1 bios system newNxosSystemImage命令安装新NX-OS中的BIOS。然后，可使用reload CLI命令中断地重新加载交换机。请勿使用reload system non-disruptive命令。随后，NX-OS的ISSU可以无中断地执行，因为ISSU可以检测到BIOS已升级。
- 有关详细信息，请参阅步骤12和步骤14。
注意：64 Gbps交换矩阵交换机的具体准则：
激活64 Gbps交换矩阵交换机上的BIOS更新的机制已更改。在首次升级到NX-OS 9.4(5)或更高版本后，建议也升级交换机EPLD。此EPLD包含新功能，允许交换机的CPU独立重新通电，同时仍保持无中断流量转发。所有EPLD升级都会中断，因为交换机作为EPLD升级的一部分重新加载。在首次升级到NX-OS 9.4(5)或更高版本后，此操作只能完成一次。
有关详细信息，请参阅步骤14。
11.验证Tmp文件目录的使用率是否不超过9%
某些MDS交换机使用/var/volatile/tmp目录，而其它交换机使用/var/tmp目录。运行show system internal flash | inc "/var/tmp|/var/volatile/tmp"命令，检查以下两个命令上的可用空间：
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#
注意：上一个示例显示文件系统已使用1%，因此可以安全地继续下一步。如果/var/volatile/tmp目录或/var/tmp目录的使用率超过9%，请不要继续安装，并与Cisco TAC联系。
12.从新系统映像升级Supervisor BIOS
每种特定类型的硬件都有自己的BIOS版本。具体硬件类型（如管理引擎、交换模块等）不同，编号也大不相同。如果步骤10中show install all impact命令的输出表明目标版本中存在BIOS升级，请继续执行这些步骤。
注意：NX-OS 9.4(2)中引入了一个新的管理引擎BIOS，用于CVE-2024-20397。
当当前交换机NX-OS版本介于8.4(2)和9.3(2a)之间，而目标NX-OS版本为9.4(2)或更高时，此程序适用于所有交换机型号。它还适用于运行低于NX-OS 9.4(5)的NX-OS版本的32 Gbps交换矩阵交换机。 在继续这些步骤之前，确保NX-OS映像已复制到管理引擎。
- 在运行hidden命令的每个Supervisor上手动安装最新的Supervisor BIOS:install module module_number bios system newNxosSystemImage。在具有双管理引擎的MDS 9700上，必须在每个管理引擎上执行此操作。对于MDS交换矩阵交换机，模块编号始终为1。在交换矩阵交换机上，可以在BIOS升级完成后重新加载交换机。此操作通过reload命令完成。在本示例中，从MDS 9124V交换矩阵交换机上的9.4(3a)系统映像升级BIOS:
MDS9124V# install module 1 bios system m9124v-s8ek9-mz.9.4.3a.bin

14.重新加载或安装EPLD交换矩阵交换机
- 32 Gbps交换矩阵交换机的具体准则：
如果升级是在NX-OS 9.4(5)或更高版本之后且包含BIOS升级，请重新加载运行reload CLI命令的交换机。请勿运行reload systemnon-disruptive命令。
- 64 Gbps交换矩阵交换机的具体准则：
激活64 Gbps交换矩阵交换机上的BIOS更新的机制已更改。新机制需要一次性中断交换机EPLD升级到IO FPGA版本或更高版本：
表IO FPGA版本可实现无中断BIOS更新：
| 交换机 | 最低IO FPGA版本(IO SPI 2) |
| MDS 9124V | 0.018 |
| MDS 9148V | 0.018 |
| MDS 9396V | 0.016 |
这些版本作为NX-OS 9.4(5)的一部分发布，可以在交换机运行NX-OS 9.4(5)（或更高版本）后安装。 运行install module 1 epld CLI命令升级EPLD。这包括交换机的自动中断性重新加载，以激活EPLD更新。如果EPLD未升级，则使用旧的重新加载机制，这会导致交换机在ISSU期间挂起，这包括BIOS更新。16 Gbps和32 Gbps交换矩阵交换机上不存在此功能。
更新EPLD后，后续ISSU可以激活映像中包含的任何新BIOS版本，而无需任何中断性重新加载。要确定当前EPLD版本，请运行show version module 1 epld命令。EPLD设备“IO SPI 2”是必须与上表匹配的版本。
以下是MDS 9148V交换机的示例，显示“IO SPI 2”版本为0.013，该版本低于所需的0.018版本：
MDS9148V# show version module 1 epld
EPLD Device Version
---------------------------------------
MI IO SPI 0.011
IO SPI 2 0.013
有关EPLD安装和更新的详细信息，请参阅MDS 9000系列EPLD固件版本9.4(5)的发行说明，其中包括所有MDS文档。
15.检验安装。
通过运行show version命令并注意系统和kickstart版本是预期版本，验证安装是否成功并完成：
