22.3. 使用规则发现不同供应商的硬件

如果拥有异构硬件环境，您可以使用内省规则来分配凭证和远程管理凭证。例如，您可能需要单独的发现规则来处理使用 DRAC 的 Dell 节点。

流程

  1. 创建名为 dell-drac-rules.json 并包含以下内容的文件： 

    [
    {
        "description": "Set default IPMI credentials",
        "conditions": [
            {"op": "eq", "field": "data://auto_discovered", "value": true},
            {"op": "ne", "field": "data://inventory.system_vendor.manufacturer",
             "value": "Dell Inc."}
        ],
        "actions": [
            {"action": "set-attribute", "path": "driver_info/ipmi_username",
             "value": "SampleUsername"},
            {"action": "set-attribute", "path": "driver_info/ipmi_password",
             "value": "RedactedSecurePassword"},
            {"action": "set-attribute", "path": "driver_info/ipmi_address",
             "value": "{data[inventory][bmc_address]}"}
        ]
    },
    {
        "description": "Set the vendor driver for Dell hardware",
        "conditions": [
            {"op": "eq", "field": "data://auto_discovered", "value": true},
            {"op": "eq", "field": "data://inventory.system_vendor.manufacturer",
             "value": "Dell Inc."}
        ],
        "actions": [
            {"action": "set-attribute", "path": "driver", "value": "idrac"},
            {"action": "set-attribute", "path": "driver_info/drac_username",
             "value": "SampleUsername"},
            {"action": "set-attribute", "path": "driver_info/drac_password",
             "value": "RedactedSecurePassword"},
            {"action": "set-attribute", "path": "driver_info/drac_address",
             "value": "{data[inventory][bmc_address]}"}
        ]
    }
]
    • 请替换此例中的用户名和密码值以适合您的环境：

  2. 将规则导入 ironic： 

    $ openstack baremetal introspection rule import dell-drac-rules.json
