= About the FirmwareSchema resource
|
|
|
|
BIOS settings vary among hardware vendors and host models. A `FirmwareSchema` resource is a read-only resource that contains the types and limits for each BIOS setting on each host model. The data comes directly from the BMC through Ironic. The `FirmwareSchema` enables you to identify valid values you can specify in the `spec` field of the `HostFirmwareSettings` resource. The `FirmwareSchema` resource has a unique identifier derived from its settings and limits. Identical host models use the same `FirmwareSchema` identifier. It is likely that multiple instances of `HostFirmwareSettings` use the same `FirmwareSchema`.

a| The `spec` is a simple map consisting of the BIOS setting name and the limits of the setting. The fields include:
|
|
|
|
* `attribute_type`: The type of setting. The supported types are:
|
|
** `Enumeration`
|
|
** `Integer`
|
|
** `String`
|
|
** `Boolean`
|
|
* `allowable_values`: A list of allowable values when the `attribute_type` is `Enumeration`.
|
|
* `lower_bound`: The lowest allowed value when `attribute_type` is `Integer`.
|
|
* `upper_bound`: The highest allowed value when `attribute_type` is `Integer`.
|
|
* `min_length`: The shortest string length that the value can have when `attribute_type` is `String`.
|
|
* `max_length`: The longest string length that the value can have when `attribute_type` is `String`.
|
|
* `read_only`: The setting is read only and cannot be modified.
|
|
* `unique`: The setting is specific to this host.
