我们最近在进行网络更改时遇到了几个影响集群的实例。这导致主主机重新启动，因为它检测到网络丢失，然后导致系统中断。集群配置了双网络端口，在主动和被动模式下，我们的理解是，如果检测到任何更改或故障，它将进行切换，而不会产生错误事件和系统关闭。

@roberthwl<\/user-mention>\u00a0 This should have definitely been the case \u201cIF\u201d the switches involved were configured correctly. I recently dealt with an issue were the core switch has some issues causing this, it was found after involving the switch vendor.\u00a0 \u00a0<\/p>

One other thing, the AHV version should be relatively new (for example AHV-20170830.300 or above 300) as many issues were addressed with the later releases of the AHV.<\/p>

You can involve nutanix support to review any logs or re-test with them on line (if possible), but I would probably review\u00a0switch\u00a0 logs and configuration before going that route.<\/p>","className":"post__content__best_answer"}">

We have had a couple of instances recently when making network changes that have affected our clusters. This caused a restart on the lead host due to it detecting a network loss and\u00a0 then resulted in system outages. The cluster is configured with dual networks ports in active and passive mode and the understanding was that it would switch if any change or failure was detecetd without producing error events and systems down.<\/p>","quoteUsername":"roberthwl","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

@roberthwl这绝对应该是“IF”的情况，所涉及的交换机被正确配置。我最近处理了一个问题，是核心交换机有一些问题导致这个，这是在涉及交换机供应商后发现的。

另一件事是，AHV版本应该是相对较新的(例如AHV-20170830.300或300以上)，因为AHV的后续版本解决了许多问题。

您可以让nutanix支持来检查任何日志或在线重新测试它们(如果可能的话)，但在走这条路之前，我可能会检查交换机日志和配置。

我们最近将集群更新到AHV版本NUTANIX 20170830.200，今年早些时候，并将很快再次这样做(在您的回复中拼写错误。300?)

我在集群上运行了诊断程序，在网络组件上运行了一个独立的诊断程序，它没有标记任何配置或相关组件中的任何错误或错误。

网络团队现在需要验证交换机配置是否正常。

据我所知，从硬件供应商的技术支持团队设置集群时起，一切都没有改变

We recently updated the clusters to\u00a0 AHV VERSION NUTANIX 20170830.200, earlier this year and would look to do so again soon ( typo on your reply .300?)<\/p>

I had run diagnostics on the cluster and a seperate one on network components which didnt flag any faults or errors inany config or associated components.<\/p>

The network team would now need to verify the switch configuration is ok.<\/p>

As far as I know nothing has been changed from when the clusters were setup by the hardware providers technical support team<\/p>","quoteUsername":"roberthwl","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

@roberthwl发布的最后一个数字是。300或以上。如果您能够在一个节点上测试这一点，这将对查看物理交换机问题和nutanix集群有很大帮助，您可以在我们的支持下打开一个案例，让他们查看一些日志。如果没有，日志是我们所有的，它们可以查看为什么事情没有按照预期发生。

@roberthwl<\/user-mention>\u00a0the last number on release is .300 or above.\u00a0 If you are in a position to test this on one node, that would help a lot looking at \u00a0both physical switch issues and nutanix cluster, you can open a case with our support and have them look at some logs. If not, logs is all we have and they can be reviewed to see why things did not happen as expected.<\/p>","quoteUsername":"sbarab","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
