Nutanix群集移动和CVM IP更改

徽章

你好，

我们计划将一些Nutanix群集移至新位置，我们已经知道，无法为安装进行网络VLAN和IP设置。

我们找到了有关如何更改CVM IP的文档，您首先建议是保持初始网络。
因此，我们应该理解有关IP重新配置过程的论点是什么，我们可以遇到一些绩效问题吗？

在某些情况下，我们希望将数据保留在群集上，而其他则不照顾它们。因此，管理这一不同的举动的最佳选择是什么。

而且，如果您中的某些人已经执行此类操作，您是否可以分享您的反馈或建议。

感谢您的回答。

问候。

@EH_GIP_SYSTEMS<\/user-mention>\u00a0\/David,<\/p>

To begin with, the perfromance in the cluster does not depend on what Ip address the cluster components have. So you can change IP addresses for the cluster components and expect the same perfromance if the connecting devices like switches and routers are configured to handle the new IP addresses and vlan in the environment.<\/p>

The best document I know, to perform the task is:<\/p>

\u201chttps:\/\/portal.nutanix.com\/#\/page\/docs\/details?targetId=Advanced-Setup-Guide-AOS-v511:ipc-cvm-ip-address-reconfigure-t.html<\/a>\u201d<\/p>

The above is for AOS 5.11 and the components associated like hypervisor and IPMI. You can get the same document for older releases as well, they are mostly similar as long as your AOS is not several years old (Anything above AOS .5.5 should work).<\/p>

There is a script that does the job called \u201dexternal_ip_reconfig\u201d<\/strong> that does the real change, but for this to work properly you need to follow all steps recommended <\/strong>there, as missing a necessary step can cause un-necessary delays in the process.<\/p>

Hello,<\/p>

We plan to move some nutanix cluster to a new location and we already know that it will not be possible to keep the network vlan and IP\u00a0setup for the installation.<\/p>

We found the document on how to change the CVM IP and you first advice is to keep the initial network if possible.
So we should understood what are the argument pro and against regarding the IP reconfiguration process, can we have some performance issue?<\/p>

In some case we want to keep the data on the cluster and other don't take care of them. So what are the best choice to manage this different move.<\/p>

And if some of yours have already perform this kind of operation, could you share your feedback or advice on that.<\/p>

Thanks for your answers.<\/p>

@eh_gip_systems/大卫，

首先，群集中的完美度并不取决于群集组件所具有的IP地址。因此，您可以更改群集组件的IP地址，并期望如果配置了连接设备（例如开关和路由器）以处理环境中的新IP地址和VLAN，则可以期待相同的效果。

我知道执行任务的最好的文档是：

“https://portal.nutanix.com/#/page/docs/details?targetId = advanced-setup-guide-aos-aos-v511:ipc-cvm-ip-ip-address-reconfigure-t.html透明

以上是针对AOS 5.11的，以及与操纵虚拟机和IPMI相关的组件。您也可以为较旧的版本获得相同的文档，只要您的AOS不使用几年（AOS .5.5.5的任何东西），它们通常都相似。

有一个脚本可以完成该作业的称呼”外部_ip_reconfig”这是真正的变化，但是要使这样做才能正常工作，您需要遵循建议所有步骤在那里，由于缺少必要的步骤会导致此过程中不必要的延迟。

正如文档中所述，我们需要注意三种情况：

  • 更改同一子网中CVM的IP地址。
  • 将CVM的IP地址更改为新的或不同的子网。

    在这种情况下，外部IP地址重新配置脚本成功工作如果新子网配置了所需的开关，并且CVM可以在新子网中相互通信。

  • 将CVM的IP地址更改为如果要将群集移至新的物理位置，则新的或不同的子网。

    在这种情况下，外部IP地址重新配置脚本成功工作如果CVM仍然可以在旧子网中相互通信。

当您注意到第二和第三种情况时，您可能需要网络管理员的帮助（如果不是您），以正确配置交换机。

多次查看上述文件，并询问有关此文件的任何问题。我很乐意回应您的担忧；而且，如果您以前从未做过此事，我建议您与我们的支持中心开设案例。

最后一个建议可能会在此过程中更容易处理的任何汇编，这是一个事实，即，只要您可以访问硬件的IPMI地址，我们就可以修改任何网络配置以使群集中的事物工作。当您可以物理访问硬件时，这是最简单的。您可以访问BIOS来更改每个HyperViosr的IPMI VLAN和网络设置。

我意识到以上内容太多了，但是我很乐意回应您对此的任何担忧。

你好 @sbarab，，，，

感谢您的回答。

我们已经查看了您共享的文档，这将是我们将应用的过程，我们正在寻找一些已经应用的用户的反馈。

因为在文档中，这句话使我们认为这不是那么容易，并且可能会产生一些后果（不适当的清洁等）：

在决定更改CVM，HyproVisor主机和IPMI IP地址之前，请考虑通过重新配置路由器和开关而不是Nutanix节点和CVM，将现有IP地址架构纳入新基础架构的可能性。

这就是为什么我们试图了解该更改者是否对集群产生影响的原因。因此，如果您没有确认，这对我们来说是可以的，当我们计划执行任务时，我们将在开始之前打开支持案例，以确保如果事情出错，我们可以得到支持。

大卫。

Hello@sbarab<\/user-mention>,<\/p>

Thanks for your answer.<\/p>

We have already looked the document you have shared, it will be the process we will apply and we were looking for some feedbacks of users\u00a0who have already apply it.<\/p>

Because in the document this sentence, made us\u00a0think than it was not so easy and could have\u00a0some consequences (not proper cleaning, etc)\u00a0:<\/p>

Before you decide to change the CVM, hypervisor host, and IPMI IP addresses, consider the possibility of incorporating the existing IP address schema into the new infrastructure by reconfiguring your routers and switches instead of Nutanix nodes and CVMs.<\/p> <\/blockquote>

That\u2019s why we are trying to understand if this changer can have an impact or not\u00a0on the cluster. So if you confirm not, it\u2019s ok for us and when we\u00a0plan to\u00a0perform the task we will open a\u00a0support case\u00a0before to start, to\u00a0be sure than we can be supported if the things go wrong.<\/p>

@eh_gip_systems/大卫，

我可以确认群集性能和操作可能不会仅通过将IP地址链接到另一个子网或VLAN来影响。确定因素（鉴于正确配置了管理程序和CVM的事实）是涉及的新开关和路由器，因为它们需要正确配置，因此它们可以接受群集网络数据包并将其路由到正确的目的地并管理网络流量。

要回到您的观点，如果您可以选择移动涉及的开关和路由器，并在新环境中与以前完全相同（确保网络设备可以访问可能是一项很难的任务）他们在内部和外部需要的所有内容），那么您无需在群集方面更改任何内容。

但是，我相信您可能会在提到的文件之后以及在我们的支持的帮助下安排更改群集IP的问题，这是我自己和我所提到的。 @hitesh0801。

问候，

@EH_GIP_SYSTEMS<\/user-mention>\u00a0\/David,<\/p>

I can confirm that cluster performance and operations may not be affected by simply chaining the IP address to another subnet or vlan.\u00a0The determining factors (given the fact that the hypervisors and CVMs are configured correctly) are the new switches and routers involved, as they need to be configured properly so they can accept cluster network packets and route them to the correct destinations and mange the network traffic.<\/p>

To get back to your\u00a0point,\u00a0if you have the option of the moving the involved switches and routers\u00a0with the hypervisors and configure them in the new environment exactly the same as before (which may be a hard task to make sure the network devices can access all they need Internally and externally), then you need not change any thing on the cluster side.<\/p>

However, I believe you may be better off just arranging for the change of cluster IP following the document mentioned and of course with help from our support as was mentioned by myself and\u00a0@HITESH0801<\/user-mention>\u00a0.<\/p>
