在HA中更换Catalyst 9000的Supervisor模块或堆叠成员
简介
本文档介绍如何在HA（高可用性）设置中替换Supervisor模块或Catalyst 9K交换机的堆叠成员。
先决条件
要求
Cisco建议您熟悉Catalyst 9K交换机上的堆叠、堆叠式虚拟(SVL)和“捆绑包”与“安装”引导模式相关概念。
使用的组件
本文档中的信息基于以下软件和硬件版本：
- C9200
- C9300
- C9400
- C9500
- C9600
本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您的网络处于活动状态，请确保您了解所有命令的潜在影响。
背景信息
本文档包括替换堆叠式交换机类型成员的过程：
- C9200/C9300堆叠成员
- C9500使用SVL
- C9400/C9600机箱管理引擎采用各种操作模式（独立式、双管理引擎、SVL和四管理引擎SVL）。
更换C9300或C9200堆叠的成员
在本示例中，您将替换C9300堆叠的成员。（本示例中的交换机在“安装”引导模式下使用交换机2）。
验证更换前
检查当前堆栈状态并准备交换。确保将交换机上的boot变量设置为指向正确的程序包文件（如果启动模式为“安装”）或bin文件（捆绑启动模式）并启用自动启动。
cat9K#show boot

Current Boot Variables:

Manual Boot = no
Enable Break = yes
Boot Mode = DEVICE
iPXE Timeout = 0
C9300#show run all | in software auto
no software auto-upgrade source url
software auto-upgrade enable
检查堆栈是否以全环方式物理连接，即，如果您关闭了相关交换机成员的电源，则现有堆栈不会拆分以导致堆栈合并。验证后，请继续下一步。

C9300#redundancy force-switchover System configuration has been modified. Save? [yes/no]: yes Building configuration... Compressed configuration from 11673 bytes to 4403 bytes[OK]Proceed with switchover to standby RP? [confirm]
替换
关闭需要更换的成员交换机电源，断开与其之间的电源堆栈和数据堆栈电缆。在电源关闭状态下，使用新成员替换该成员，重新连接数据堆栈电缆并打开电源。
如果堆叠处于“捆绑包”引导模式，请在启动时中断到新交换机的ROMMON。借助USB盘或OOB TFTP访问，使用与现有堆叠相同的软件版本手动引导新交换机。

rommon 2 > boot usbflash0:cat9k_iosxe.17.03.01.SPA.bin
如果堆叠处于“安装”引导模式，则当堆叠的当前活动状态检测到新成员交换机上存在不兼容的软件版本或引导模式时，必须启动自动软件升级。通常，此阶段不需要手动干预。

更换C9400独立机箱的冗余管理引擎
在本示例中，您将更换C9404机箱的Active管理引擎。（本示例中的交换机在“安装”引导模式下用于插槽3。）
验证更换前
检查交换机上的引导变量是否设置为指向正确的程序包文件（如果引导模式为“安装”）或bin文件（捆绑引导模式），并且已启用自动引导。

no software auto-upgrade source url

如果需要替换主用Supervisor(如本示例中的我们)，请执行到备用管理引擎的故障转移，并等待它接管主用角色。如果要替换备用管理引擎，请跳过此步骤。

替换
从机箱中移除有故障的Supervisor，插入新的有故障的Supervisor，同时插入控制台电缆。
如果活动Supervisor在“捆绑”引导模式下运行，则在新Supervisor启动时将其中断到其ROMMON中。借助USB盘或OOB TFTP访问，使用与活动Supervisor相同的软件版本手动引导Supervisor。

更换C9400双管理引擎StackWise虚拟管理引擎
此示例适用于C9400 Stackwise虚拟设置（每个机箱一个管理引擎），其中机箱–1的管理引擎（活动交换机）已损坏，需要更换。SVL在“安装”引导模式下运行。
验证更换前
检查当前与StackWise-Virtual相关的配置和管理引擎的状态。确保交换机上的引导变量已正确设置为指向正确的程序包文件（如果引导模式为“安装”）或bin文件（捆绑引导模式），并且已启用自动引导。

替换
关闭需要更换管理引擎的机箱的电源（在我们的示例中，它是chassis-1）。
从相应机箱（需要更换管理引擎）的背板卸下线卡。 无需将线卡完全从机箱中取出，只要线卡未连接到背板即可。这样，当插入新的管理引擎并进行预转移时，连接的远程交换机（多机箱etherchannel）不会将其本地端口置于错误禁用状态（LACP等）。

将新的Supervisor插入存在故障Supervisor的同一插槽中，然后接通电源。它必须在单机模式（非SVL）下启动，暂时断开Stackwise虚拟链路。
- 如果主用Supervisor在“捆绑”引导模式下运行，请将软件bin文件（与SVL的当前主用Supervisor相同）复制到新备用Supervisor的Bootflash中，并相应地更改引导字符串。
- 如果您的活动Supervisor在“安装”引导模式下运行，则不需要手动软件升级。当新的/备用Supervisor检测到不兼容的软件版本或引导模式时，必须立即由当前主用Supervisor自动升级新Supervisor的软件和引导模式。
使用Stackwise虚拟设置配置新的管理引擎。（您必须使用相同的SVL域号来匹配现有成员。）

保存配置，并关闭新管理引擎所在的机箱电源。
连接两个机箱之间的StackWise-Virtual链路，首选断开双活检测链路（如果适用）。
打开机箱电源，通过控制台监控启动过程。
- 如果您的SVL在“捆绑包”引导模式下运行，请确保新的Supervisor使用与Active相同的软件版本。否则，请再次进入ROMMON并使用正确的软件版本手动启动。
- 如果SVL在“安装”引导模式下运行，则“软件自动升级”必须负责将正确的软件版本和引导模式推送到新的管理引擎，而无需任何手动干预。

替换C9500 StackWise-Virtual的成员
在本例中，您考虑将C9500 Stackwise虚拟设置中的Switch-1（活动交换机）作为需要更换的故障交换机。SVL在INSTALL引导模式下运行。
验证更换前
检查当前与StackWise-Virtual相关的配置和交换机的状态。确保引导变量设置正确，指向packages.conf，config-register设置为0x2102。

更换C9600双管理引擎StackWise虚拟管理引擎
在本例中，您考虑的是C9600 Stackwise虚拟设置（每个机箱一个管理引擎），其中chassis-1的管理引擎（活动交换机）已损坏，需要更换。SVL在“安装”引导模式下运行。
验证更换前
检查当前与StackWise-Virtual相关的配置和管理引擎的状态。确保交换机上的引导变量已正确设置为指向正确的程序包文件（如果引导模式为“安装”）或bin文件（捆绑引导模式），并且已启用自动引导。

如果主用管理引擎在“捆绑包”引导模式下运行，请将运行软件文件（.bin文件，运行在主用设备上）的副本保存在可从新Supervisor通过其带外(OOB)管理端口访问的USB棒或本地TFTP服务器中。
- 如果需要替换主用Supervisor(如示例中所示)，请执行到备用管理引擎的故障转移，并等待备用管理引擎接管主用角色。如果要替换备用管理引擎，请跳过此步骤。

替换
关闭需要更换管理引擎的机箱的电源。在我们的示例中，它是chassis-1。
从各个机箱（需要更换管理引擎）的背板卸下线卡，StackWise虚拟链路(SVL)连接到的线卡除外。对于配置了SVL的线卡，请删除除SVL本身以外的所有连接。这样，当插入新的管理引擎并进行预转移时，连接的远程交换机（多机箱etherchannel）不会将其本地端口置于错误禁用状态（LACP等）。

将新的Supervisor插入存在故障Supervisor的同一插槽中，然后接通电源。它必须在单机模式（非SVL）下启动，暂时保持Stackwise虚拟链路和DAD链路断开连接。
如果主用Supervisor在“捆绑”引导模式下运行，请将软件bin文件（与SVL的当前主用Supervisor相同）复制到新备用Supervisor的Bootflash中，并相应地更改Bootstring。
如果您的活动Supervisor在“安装”引导模式下运行，则不需要手动软件升级。当新的/备用Supervisor检测到不兼容的软件版本或引导模式时，必须立即由当前主用Supervisor自动升级新Supervisor的软件和引导模式。
使用Stackwise虚拟设置配置新的管理引擎。（您必须使用相同的SVL域号来匹配现有成员）。

完成SSO后，继续连接双活检测(DAD)链路。
- 将线卡推回内部(用于更换管理引擎的机箱)，使那些线卡重新连接到背板。现在，重新连接电缆。
- 验证所有线卡是否引导良好，通过在线诊断测试并启用其接口，包括端口通道绑定等。

更换C9600四管理引擎StackWise虚拟管理引擎
在本示例中，您考虑采用C9600 Quad Sup Stackwise-Virtual设置（每个机箱有两个管理引擎），管理引擎出现故障并需要更换。SVL在“安装”引导模式下运行。
更换和验证
拔出有故障的主管
- 如果要更换的Supervisor是Global Active Supervisor（图中所示为Sw-1插槽3），请执行故障切换，以便全局备用（上一图中的Sw-2插槽3）接替Active。等待新的全局备用并完成SSO。（在本例中，Sw-1插槽4将成为新的全局备用插槽）。
- 如果要更换的Supervisor是Global Standby Supervisor（图中所示的Sw-2插槽3），请拔出Supervisor。等待新的全局备用并完成SSO。（在本例中，Sw-2插槽4将成为新的全局备用插槽）
- 如果要更换的Supervisor是ICS Supervisor（图中所示的Sw-1插槽4或Sw-2插槽4），请拔出Supervisor。
插入新的管理引擎
- 如果新的管理引擎运行在17.x代码上，则步骤是直接向前的。只需插入新的管理引擎。如果ICS管理引擎有17.x映像，它们将自动启动，并成为Quad-sup的一部分。即使它运行的17.x代码与生产设置中运行的17.x代码不同，Software Auto-upgrade也会自动在INSTALL模式下使用相同的17.x代码升级ICS管理引擎。
- 如果新的管理引擎运行的是16.x代码，或者您不确定它运行的代码，请尝试将管理引擎插入备用机箱中，并将其升级为17.x代码。如果没有备用机箱需要升级，则必须执行这些步骤。
- 此步骤非常重要。插入ICS管理引擎并使用Ctrl+C将其中断为rommon。如果您未能打入ROMMON并且管理引擎启动了16.x代码，则可能会关闭管理引擎所插入的整个机箱
查找任何与SVL相关的rommon变量。这些变量以D_STACK开头。通常，新的Supervisor没有设置这些变量。
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,"
取消设置前面显示的所有变量
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
查找变量“SWITCH_NUMBER=1”。 如果交换机编号是2，则将变量设置为1。如果已经是1，请移至下一步。
rommon 1 > SWITCH_NUMBER=1
设置为手动启动Supervisor。
rommon 1 > MANUAL_BOOT=YES
使用17.x代码上的USB/TFTP以捆绑模式手动启动ICS管理引擎。请勿在rommon中更改引导变量。只需从rommon手动启动。
- 当Supervisor在SVL模式下检测到现有ICS时，它将被重置，以便从独立模式转换到Stackwise虚拟模式。由于禁用了自动引导，它可能会再次回退到rommon模式。
取消设置手动引导以启用自动引导。
rommon 1 > unset MANUAL_BOOT
使用17.x代码上的USB/TFTP以捆绑模式手动启动ICS管理引擎。请勿在rommon中更改引导变量。只需从rommon手动启动。此步骤以捆绑包模式启动ICS。
