我不知道 hdiskX、fscsiX 和 路径的名称（例如 500507680b256624,9000000000000）。它们在每个主机上可能不同。
我想用 path_status 搜索 hdisX：Defined，因为我想用任何 Defined搜索主机> 路径。像这样的：
- name: Host
debug:
var: inventory_hostname
when: " ansible_facts.mpio.paths.*.*.*.path_status == 'Defined'"
我不知道如何在嵌套字典变量中查找属性。谁能给个提示？
【问题讨论】：
这能回答你的问题吗？ Search Dictionary Values in Ansible 请更具体一点 1）您的示例数据仅包含“path_status”的定义值 2）由于有多个值，您到底想要哪个条件？所有这些都必须定义？至少我必须定义一个？全面的？每个fcs？每个高清？ 更具体地说： 1) 是的，path_status 可能是可用的或已定义的。 2）需要找到任何（每个主机至少一个）定义的路径。 【参考方案1】：希望以下内容能满足您的要求，并为您提供有关您可能想要搜索、研究和使用的一组过滤器的足够线索。
我基本上将您数据中的所有path_status 条目减少为符合我们标准的唯一值的单个一维列表，并检查其长度是否等于1（即至少一个path_status 包含'Defined' in主机的全部数据）。
以下剧本：

- hosts: localhost
gather_facts: false
vars:
ansible_facts:
mpio:
# Your orig data on a single line for playbook readability
# Modified with two positive results for below tests.
paths:
