ERROR_CLUSTER_PARAMETER_MISMATCH
Property validation must consider relationships between parameters
ERROR_CLUSTER_PARAMETER_MISMATCH is returned when two or more resource settings conflict as a set. This differs from a malformed property value: each value may have the right type and range, yet the combination cannot describe a workable resource. Typical examples are mutually exclusive network modes, a path that contradicts another storage property, or a timeout and recovery policy that the resource type rejects together.
Review the complete effective property set, including unchanged values already stored in the cluster database. Management software often sends only the edited property, while the resource DLL validates it against existing private and common properties. Record the proposed list and the prior list, then use the resource type’s validate-properties control path before committing. Changing one parameter repeatedly without examining its paired constraints usually moves the conflict rather than resolving it.
How to isolate the conflicting pair
- Export all common and private properties before applying the change.
- Compare dependent-resource properties that share a network, disk, name, or identity.
- Run validation with the resource offline when the resource type requires it.
- Check vendor resource DLL documentation for conditional or mutually exclusive fields.
