您可以使用此过程在 Nexus 3232C 存储交换机上安装 NX-OS 软件。

开始之前

验证您是否具有以下条件：

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）。
"Cisco以太网交换机页面"。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。

安装或升级软件

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。

完成 "准备安装 NX-OS 和 RCF" 中的步骤，然后按照以下步骤操作。

步骤

将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
此示例验证交换机可以访问 IP 地址为 172.19.2.1 的服务器：
s2# ping 172.19.2.1 Pinging 172.19.2.1 with 0 bytes of data: Reply From 172.19.2.1: icmp_seq = 0. time= 5910 usec.
如果您是首次设置交换机，请跳至第 5 步。如果要升级交换机，请继续下一步。

检查每个节点存储端口和存储盘架端口的管理或运行状态。

显示节点存储端口属性：

storage port show

显示示例

cluster1::*> storage port show
Speed                     VLAN
Node           Port Type  Mode    (Gb/s) State    Status      ID
-------------- ---- ----- ------- ------ -------- --------- ----

               e5a  ENET  storage    100 enabled  online      -
               e3b  ENET  storage    100 enabled  online      -
cluster1-02

               e5a  ENET  storage    100 enabled  online      -
               e3b  ENET  storage    100 enabled  online      -
.
.

显示存储架端口属性：+ storage shelf port show

显示示例

cluster1::*> storage shelf port show
Shelf ID Module State        Internal?
----- -- ------ ------------ ---------
1.4
       0 A      connected    false
       1 A      connected    false
       2 B      connected    false
       3 B      connected    false
.
.

确认已为交换机启用交换机健康监控 (CSHM)，以便对其进行监控：

system switch ethernet show

显示示例

cluster1::> system switch ethernet show
