执行APIC自动升级的步骤

简介

本文档介绍思科应用策略基础设施控制器(APIC)的自动升级功能的工作原理。

何时需要它？

在现有的流程中，无论何时通过退货授权(RMA)收到新的APIC或新采购的APIC，都必须运行与ACI交换矩阵中相同的APIC版本才能加入集群。这要求先升级新APIC以匹配现有集群的版本，然后再将其添加到交换矩阵，这非常耗时且需要手动操作。

当您需要此功能时，有两个使用案例。

1. 更换故障APIC (RMA APIC)

2. APIC集群扩展

先决条件

为了简化操作步骤并使其即插即用，从ACI版本6.0(2)及后续版本开始引入了APIC自动升级功能。

通过替换或添加将新APIC引入交换矩阵时，APIC软件必须与集群上运行的软件相匹配。这通常需要升级，升级过程需要花费额外时间才能完成，并且APIC需要花费额外时间才能加入交换矩阵

这是不需要任何配置的自动功能。

拓扑

在此拓扑中，您有三个运行ACI版本6.0(5h)的APIC，APIC3出现故障并需要更换。

执行APIC自动升级的步骤

收到RMA APIC后，请配置思科集成管理控制器(CIMC) IP以匹配先前的CIMC地址。

步骤1: 登录CIMC GUI。

第二步： 通过键盘、视频和鼠标KVM访问APIC。

导航到Launch vKVM > Click on it > One more window tab is going open > Click on hyperlink

第三步： 初始化新APIC以检查其运行的APIC版本（您可以使用任何虚拟交换矩阵发现参数，如交换矩阵名称、交换矩阵ID、TEP池等）

第四步： 初始化新APIC后，请检查版本（您可以看到现有APIC版本为5.2.5c）

apic3# acidiag version <== To check the APIC version

5.2.5c

第五步： 使用给定命令全新重新加载新APIC。

acidiag touch clean <<== Commands to remove all configuration and reboot the devices

acidiag touch setup

acidiag reboot

第六步： 收集 sam_exported.config从正在运行的APIC中获取此信息，以便在APIC初始化时使用。

apic1# cd /data/data_admin

apic1# pwd

/data/data_admin <=== Location of sam_exported.config file

apic1# ls -l | grep sam

-rw-r--r-- 1 root root 349 Jul  3 07:32 sam_exported.config

apic1# cat sam_exported.config

Setup for Active and Standby APIC

fabricDomain= bgl-aci04

fabricId= 1

systemName= bgl-aci04-apic1 <== APIC1 hostname , change based on APIC3

controllerID= 1

tepPool= 10.0.0.0/16

infraVlan= 3967

GIPo= 225.0.0.0/15

clusterSize= 5

standbyApic= NO

enableIPv4= Y

enableIPv6= N

firmwareVersion= 6.0(5h)

ifcIpAddr= 10.0.0.1

apicX= NO

podId= 1

standaloneApicCluster= no

oobIpAddr= 10.197.204.114/24 <== APIC1 OOB IP, Change based on APIC3

步骤 7. 使用步骤6中收集的数据初始化新的APIC。

步骤 8 从APIC01 GUI停用故障APIC3

导航到System > System Settings > Controllers > Cluster as Seen by Node

单击设备右侧的三个点。点击Decommission

步骤 9 验证节点的管理员状态，它显示为“停止服务”，并且停用选项呈灰色显示。

步骤 10 从机架中移除有故障的APIC3，然后在机架中安装新的APIC3。

步骤 11 将新APIC安装到机架中后，接通新APIC3的电源并连接电缆。电缆包括交换矩阵上行链路和管理端口。

步骤 12 等待10-15分钟，以便新APIC可以通电。通过CIMC KVM验证新APIC是否已通电且我们可以看到登录提示。（登录仅适用于rescue-user）

步骤 13 从APIC01 GUI委托APIC03。

导航到System > System Settings > Controllers > Cluster as Seen by Node

点击设备右侧的三个点>点击Commission

第14步：添加在故障/旧的APIC中使用的CIMC IP地址、用户名、密码，我们将替换这些地址。点击Validate。一旦验证成功。

输入APIC名称、管理密码（交换矩阵中使用的当前密码）、POD ID、带外管理地址和IPV4网关，然后点击Apply。（所有这些参数在更换时均属于旧的APIC）。

步骤 15 现在等待10-15分钟，以便使用5.2(5c) APIC版本将新APIC添加到交换矩阵。

步骤 16 现有APIC会自动将此新APIC升级到6.0(5h)，并将它添加到集群中。您可以让其继续运行30分钟，并再次检查以前的avread输出。

步骤 17 如果自动APIC升级失败，则随后发生故障。

步骤 18. 对于失败的情况，您可以执行全新重新加载并将新APIC添加回ACI交换矩阵以进行发现，从而始终重新触发自动APIC升级。

如果这些步骤无法解决问题，请收集Techsupport日志并联系思科TAC以获得进一步帮助。
