大家好，
在部署Nutanix 3节点群集时面临奇怪的问题。
一切都完成了，没有任何部署Nutanix的问题。重新启动节点后，我们无法在手动重新启动网络服务的ILO之后到达AHV节点IP，然后可以触及AHV和CVM，并且所有群集都是正常的。发生这些只有我重新启动节点或关闭AHV。
重新启动之前，网络接口仅启动。
从开关侧面，我们配置了访问端口VLAN标记1010。
此处ETH4连接在开关-1端口1上，并且相同的ETH6连接在Switch-2端口2上
注意：Switch-1和Switch-2均被堆叠
型号：思科SG350xG
AOS：5.20.1.1 LTS
这是我的配置

Hello People,
\u00a0Facing strange issues on deploying Nutanix 3 node cluster.
\u00a0Everything is completed without any issues deploying Nutanix. After restarted the nodes we are not able to reach AHV Node IPs after logging into ILO manually restarted the network services and then the AHV and CVM are reachable and all the cluster is normal. These happen only I restarted the nodes or shutting down AHV.
Before restarting, network interfaces are up only. <\/strong>
\u00a0 From Switch side we have configured access port VLAN tagged 1010.
\u00a0 Here eth4 is connected on switch-1 port 1 and same eth6 is connected on switch-2 port 2
\u00a0 Note : Both switch-1 and switch-2 is stacked<\/strong>
\u00a0 Model : Cisco SG350XG
\u00a0 AOS : 5.20.1.1 LTS<\/strong>
Here my config

你好senthil_p，

感谢您与我们联系。在没有群集访问或任何日志的情况下，我们会说我们应该遵循NIC上的配置。

LACP：关闭
lacp-fallback：是的
LACP_SPEED：关闭

尝试更改以下提到所有主机上的详细信息，并检查它是否解决了报告的问题。如果没有，我建议打开一个带有Nutanix支持的案例，以对报告的问题进行更详细的调查。

愉快的故障排除！

Hello Senthil_P,<\/p>

Thanks for reaching out to us. In absence of cluster access or any logs, we would say that we should\u00a0following config on NICs.<\/p>

    lacp: off<\/pre>
    lacp-fallback: true<\/pre>
    lacp_speed: off<\/pre>
Try changing below mentioned details on all hosts and check if it fixes reported issue. If not, I would recommend opening a case with Nutanix Support for more detailed investigation of reported issue.<\/p>
Happy Troubleshooting !!<\/p>","quoteUsername":"rohan.saksena-55595","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
