从元件管理器手动横向扩展（添加SF）VPC-DI功能
简介
本文档介绍如何在无需重新加载或重新部署VPC网关的情况下将手动横向扩展（添加一个新的服务功能卡）到运行的VPC-DI（虚拟数据包核心 — 双实例）设置。此功能旨在支持新的网关容量扩展要求。
先决条件
要求
Cisco 建议您了解以下主题：
- 思科超虚拟数据包核心解决方案组件
- 超自动化服务(UAS)
- 弹性服务控制器(ESC)
- OpenStack
除此之外，您还需要以下内容作为前提条件：
- 在运行正常的环境中运行且配置正确的VPC-DI全堆栈实例
- 所有必需的网络配置都与目标新SF（服务功能）卡的DI（双实例）和服务网络相关
- 所需资源和权限可在Openstack级别（云）示例、主机、CPU RAM和配额等中使用。
- ESC处于健康状态。
- 任何其他依赖项都取决于您的云设置设计，如其他接口、网络或资源。
- 云状态正常，没有警告或警报。
使用的组件
本文档中的信息基于以下软件和硬件版本：
- USP 6.6
- ESC:4.4.0(88)
- StarOS:21.12.0(71244)
- 云 — CVIM 2.4.16
- UCS M4 C240服务器 — 4pc
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
该设置称为没有NSO解决方案的独立AutoVNF部署设置。通过本文，在现有运行的VPC-DI设置中，人员可以无缝地添加来自EM的SF卡，以支持其他容量要求，
它包括这些VM类型。
- AutoVNF VM - 1实例
- 元件管理器VM - 2实例
- 控制功能VM - 2实例
- 会话功能VM - 2实例
- ESC(VNFM)- 2实例(IN HA)
目前，在VPC-DI网关中，您有一个SF VM处于运行状态，即一个SF卡3在应用级别处于活动状态，此处添加了另一个卡（SF卡4）作为横向扩展活动的一部分。

步骤2.确保在VNFM(ESC)监控时所有VM状态均为ALIVE。如果任何VM出错，则必须先修复它，然后再继续本练习。

步骤3.确保VPC-DI网关内的所有卡都处于正常状态，并且emctrl状态为“活动”。

还有一些针对EM的健康检查列表不在本文讨论范围之内。因此，如果发现任何其他错误，必须相应地采取适当的措施。
步骤5.从EM添加新的SF卡4。
