如何使用Ansible官方模块更高效的给VMware VM Host添加磁盘？
How to add disk to VMware's VM host more efficiently by using Ansible offical module?
环境
- OS版本：分OS7.5
- Ansible 版本：2.8.4 和 python2.7.5
- ESXi 和 VCenter 版本：6.5.2
目的
我已经完成了我的代码，但我想知道是否有更好的方法通过 Ansible 官方模块.

根据VMware offical document 1 VM 主机只能有 4 个 scsi 控制器，每个控制器可以连接 15 个设备。所以我必须写很多条件来防止它。
奇怪的是，从VCenter添加硬盘时，不会触发硬盘数量超过7个的问题，而Ansible的模块在unit_number超过7个时，无法增加硬盘, 并且必须更换另一个 SCSI 控制器。
除了这样做还有什么更好的办法吗？或者我可以参考和研究的东西？
感谢您的帮助和建议！
我试着重新表述一下这个问题。这远非完美，因为它不会考虑编号中的“漏洞”（即从序列中删除的磁盘或控制器）。但我认为您当前的实施也不会。我的应该使用更少的变量赋值，如果没有更多可用的插槽，它将优雅地失败。
- 从来宾获取磁盘信息（例如粘贴在 var 中）。
- 从信息中，循环配置控制器的数量。对于每个控制器，记录其密钥、编号、设备数量和最大配置设备 ID。
- 从列表中提取具有可用插槽的第一个控制器
- 如果此操作失败，则创建一个空的控制器信息以递增 scsi 设备编号，或者如果达到最大值则失败。
注意：我使用了 json_query 所以你需要 pip(3) install jmespath 在你的 ansible controller 机器上 运行 这个例子。
