你好,

Nutanix CLI非常新，我正在对DR Cluster进行大量PD测试，并使用默认前缀恢复它们。

我在想，如果有人可以帮助我一个脚本关闭所有的虚拟机的名称开始' nutanix克隆- "。

我发现这：

对于“acli vm”中的vm_name。list power_state=on | grep -v ^'虚拟机名' | awk '{print $1}' ';做acli vm。关闭$vm_name; done

这是优秀的，但我不确定如何进一步过滤虚拟机名称?

任何帮助表示赞赏。

注意:我也感谢任何帮助的脚本，然后删除任何虚拟机和关联的快照开始与' nutanix克隆- ' -通过web控制台做80左右是困难的工作。

谢谢你的时间，

亚伦

Hello,<\/p>

Very new to the Nutanix CLI and I am doing a lot of PD testing to a DR Cluster and restoring them with the default prefix.<\/p>

I was wandering if someone could help me with a script to shitdown all VM\u2019s with the name starting \u2018Nutanix-Clone-\u201d.<\/p>

I found\u00a0this<\/a>\u00a0:<\/p> 

for vm_name in `acli vm.list power_state=on | grep -v ^'VM name' | awk '{print $1}'`; do acli vm.shutdown $vm_name; done<\/code><\/pre>  
which is excellent but Im not sure how to further filter it by VM name?<\/p>  
Any help appreciated.<\/p>  
Note: Id also appreciate any help with a script that then deletes any VM and associated snapshot starting with \u2018Nutanix-Clone-\u2019 - doing 80 or so through the web console is hard work.<\/p>  
Thanks for you time,<\/p>  
Aaron<\/p>

嘿 @arboundy给我一些时间，我会在其中一个测试集群中尝试它，并将结果反馈给你。与此同时，这里有一个卫城cmdline指南对虚拟机执行操作。上面的脚本也使用这些命令对虚拟机执行操作:

https://portal.nutanix.com/page/documents/details/?targetId=Command-Ref-AOS-v5_17%3Aacl-acli-vm-auto-r.html

在这个脚本中，您可以在这里指定虚拟机名称“grep -v＾＇虚拟机名称' "，但使用不同的通配符- v'这里是用于反转匹配的，也就是不匹配"中指定的给定字符串虚拟机名称”。所以这个脚本关闭了所有虚拟机，除了名称为'的虚拟机虚拟机名称'在参数中指定。也＾正则表达式模式指定一行的开始。这可以在grep中用于匹配以给定字符串或模式开头的行。

对于“acli vm”中的vm_name。list power_state=on | grep -v ^'虚拟机名' | awk '{print $1}' ';做acli vm。关闭$vm_name; done


下面是一个在Linux中使用grep的好指南:https://www.geeksforgeeks.org/grep-command-in-unixlinux/

在您的场景中，您可以做的是使用

grep - i ^ ' Nutanix-Clone - '

给我一些时间，我会在我的实验室集群中进行实验，然后再回复你。同时，你也可以尝试使用卫城指南和脚本。

如果你还需要什么就告诉我。微笑:

Hey @arboundy<\/user-mention>\u00a0,\u00a0 about the script give me some time I will try it out in one of the test clusters and get back to you with the result. In the meantime here is an Acropolis cmdline guide<\/strong> to perform actions on a VM. The above script also uses these commands to perform the actions on the VMs:<\/p>

https:\/\/portal.nutanix.com\/page\/documents\/details\/?targetId=Command-Ref-AOS-v5_17%3Aacl-acli-vm-auto-r.html<\/a><\/p>

\u00a0<\/p>

In this script you can specify the VM names here \u201cgrep -v ^<\/strong>'VM name<\/strong>' \u201c, but with a different wildcard i.e \u2018-v<\/strong>\u2019 here is for invert matching i.e here\u00a0which does not matches the given string specified in \u201cVM name<\/strong>\u201d. So this script is shutting down all the VMs other than the VMs with name\u00a0\u2018VM name<\/strong>\u2019 specified in the argument. Also the ^ <\/strong>regular expression pattern specifies the start of a line. This can be used in grep to match the lines which start with the given string or pattern.<\/p> 

for vm_name in `acli vm.list power_state=on | grep -v ^'VM name' | awk '{print $1}'`; do acli vm.shutdown $vm_name; done<\/code><\/pre>  

 Here is a good guide to\u00a0using grep in Linux:https:\/\/www.geeksforgeeks.org\/grep-command-in-unixlinux\/<\/a><\/p>  
In your scenario what you can do is use\u00a0<\/p>  
grep -i ^\u2019Nutanix-Clone-\u2019<\/code><\/pre>  
\u00a0<\/p>  
Give me some time I will experiment this in one of my lab clusters and get back to you. In the mean time you can try it out too using the Acropolis guide and the script.<\/p>  
\u00a0<\/p>  
Let me know if you need anything else.\u00a0\":smile:\"<\/p>","quoteUsername":"AnishWalia20","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

谢谢 @AnishWalia20-由于我还没有痊愈(确切地说是几天)，我期待你的回复，并真诚地感谢你的帮助。

嘿 @arboundy所以我尝试和试验了剧本，下面是你可以做的:

  1. 关闭所有名称为“Nutanix-Clone-”的虚拟机:登录集群中的一个cvm，运行以下脚本:

    Cvm $ for vm_name in ' acli vm。list power_state=on | grep -i ^'Nutanix-Clone-' | awk '{print $1}' ';做acli vm。force_off vm_name美元;完成
    以上的输出
    这将关闭所有以name开头的虚拟机。”Nutanix-Clone -”。

  2. 删除任何以' Nutanix-Clone '开头的虚拟机:
    Cvm $ for vm_name in ' acli vm。list power_state=off | grep -i ^'Nutanix-Clone-' | awk '{print $1}' ';删除$vm_name delete_snapshots="true";完成
    以上的输出


    在上述场景中，以name '开头的虚拟机Nutanix-Clone -这些都在关闭和他们一起快照被删除。选择“delete_snapshots = " true删除虚拟机关联的快照。

您需要做的唯一一件事就是为每个虚拟机输入“yes”，因为将会有一个确认删除的提示符。:笑:

如果你还有其他需要帮助的地方请告诉我，我很乐意帮忙。笑脸:

Hey @arboundy<\/user-mention>\u00a0so I tried out and experimented with the scripts and here is how you can:<\/p>

\u00a0<\/p>

  1. Shutdown all VM\u2019s with the name starting \u2018Nutanix-Clone-\u201d : Login to one of the CVMs on the cluster and run this script: \t

    cvm$ for vm_name in `acli vm.list power_state=on | grep -i ^'Nutanix-Clone-' | awk '{print $1}'`; do acli vm.force_off $vm_name; done
    <\/code><\/pre>  \t
    \"//www.jhbzcj.com/next/how-it-works-22/\"
    Output of the above<\/figcaption><\/figure> \tThis will power off all the VMs starting with name \u201cNutanix-Clone-<\/strong>\u201d.\u00a0

     \t\u00a0<\/li> \t
  2. Deletes any VM starting with \u2018Nutanix-Clone\u2019: \t
    cvm$ for vm_name in `acli vm.list power_state=off | grep -i ^'Nutanix-Clone-' | awk '{print $1}'` ; do acli vm.delete $vm_name delete_snapshots=\"true\" ; done<\/code><\/pre>  \t
    \"//www.jhbzcj.com/next/how-it-works-22/\"
    Output of the above<\/figcaption><\/figure>

     \tIn the above scenario the VMs Starting with name \u2018Nutanix-Clone-<\/strong>\u2019 which were in powered-off<\/strong> state along with their snapshots<\/strong> were deleted. The option \u201cdelete_snapshots=\u201dtrue<\/strong>\u201d deleted the snapshots associated with the VMs.<\/p> \t<\/li> <\/ol>
    The only thing you will have to do is enter \u201cyes\u201d for each VM as there will be a prompt for confirmation to delete.\":grin:\"<\/p>  
    \u00a0<\/p>  
    Let me know if you need help with anything else as I would be more that happy to help.\":smiley:\"<\/p>","quoteUsername":"AnishWalia20","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

嘿 @arboundy，只是跟进一下，你能执行上面的脚本并实现上面的吗?

如果你有任何疑问，请告诉我，我非常乐意为你解答。微笑:
