PDF
按照以下步骤在 Nexus 9336C-FX2 和 9336C-FX2-T 交换机上安装 NX-OS 软件。
开始之前，请先完成以下步骤。"准备安装 NX-OS 和 RCF" 。
审查要求
开始之前
请确保您拥有以下物品：
-
交换机配置的当前备份。
-
一个功能齐全的集群（日志中没有错误或类似问题）。
建议的文档
-
请查阅交换机兼容性表格，了解支持的ONTAP和 NX-OS 版本。
-
有关Cisco交换机升级和降级程序的完整文档，请参阅Cisco网站上提供的相应软件和升级指南。
-
"Cisco Nexus 9000 和 3000 升级和 ISSU 矩阵"
根据您当前和目标版本，提供有关 Nexus 9000 系列交换机上Cisco NX-OS 软件的中断式升级/降级的信息。
在页面上，选择“中断式升级”，然后从下拉列表中选择当前版本和目标版本。
关于示例
本流程中的示例使用以下开关和节点命名规则：
-
这两个Cisco交换机的名称分别是 cs1 和 cs2。
-
节点名称为cluster1-01、cluster1-02、cluster1-03和cluster1-04。
-
集群 LIF 名称为 cluster1-01_clus1、cluster1-01_clus2、cluster1-02_clus1、cluster1-02_clus2、cluster1-03_clus1、cluster1-03_clus2、cluster1-04_clus1 和 cluster1-04_clus2。
-
这 `cluster1::*>`prompt 指示集群名称。
安装软件
该过程需要同时使用ONTAP命令和Cisco Nexus 9000 系列交换机命令；除非另有说明，否则使用ONTAP命令。
步骤
-
将集群交换机连接到管理网络。
-
使用 ping 命令验证与托管 NX-OS 软件和 RCF 的服务器的连接性。
显示示例
此示例验证交换机可以访问 IP 地址为 172.19.2.1 的服务器：
cs2# ping 172.19.2.1 VRF management Pinging 172.19.2.1 with 0 bytes of data: Reply From 172.19.2.1: icmp_seq = 0. time= 5910 usec.
-
显示每个节点上连接到集群交换机的集群端口：

检查每个集群端口的管理和运行状态。
-
确认集群所有端口均已启动且状态正常：
