按照以下步骤在 Nexus 3132Q-V 集群交换机上安装 NX-OS 软件。
审查要求
开始之前
-
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
-
"Cisco以太网交换机"。请查阅交换机兼容性表格，了解支持的ONTAP和 NX-OS 版本。
-
"CiscoNexus 3000 系列交换机"。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。
安装软件
关于此任务
该过程需要同时使用ONTAP命令和Cisco Nexus 3000 系列交换机命令；除非另有说明，否则使用ONTAP命令。
务必完成以下步骤"准备安装 NX-OS 软件和参考配置文件"然后按照以下步骤操作。
步骤
-
将集群交换机连接到管理网络。
-
使用 `ping`用于验证与托管 NX-OS 软件和 RCF 的服务器的连接性的命令。
显示示例
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.

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：

显示示例
cluster1::*> system cluster-switch show -is-monitoring-enabled-operational true Switch Type Address Model --------------------------- ------------------ ---------------- ------------ cs1 cluster-network 10.233.205.90 N3K-C3132Q-V Serial Number: FOCXXXXXXGD Is Monitored: true Reason: None Software Version: Cisco Nexus Operating System (NX-OS) Software, Version 9.3(5) Version Source: CDP cs2 cluster-network 10.233.205.91 N3K-C3132Q-V Serial Number: FOCXXXXXXGS Is Monitored: true Reason: None Software Version: Cisco Nexus Operating System (NX-OS) Software, Version 9.3(5) Version Source: CDP cluster1::*> -
-
禁用集群 LIF 的自动回滚功能。集群 LIF 会故障转移到伙伴集群交换机，并在您对目标交换机执行升级过程时保留在该交换机上：
network interface modify -vserver Cluster -lif * -auto-revert false -
使用以下传输协议之一将 NX-OS 软件复制到 Nexus 3132Q-V 交换机：FTP、TFTP、SFTP 或 SCP。有关Cisco命令的更多信息，请参阅相应的指南。 "Cisco Nexus 3000 系列 NX-OS 命令参考指南" 。
