COMADMIN_E_CAT_DUPLICATE_PARTITION_NAME
COM+ partition administration: exact meaning of COMADMIN_E_CAT_DUPLICATE_PARTITION_NAME
A COM+ partition with the requested name already exists on the computer. Partition creation or rename enforces local partition-name uniqueness.
Windows describes this condition as “The specified partition name is already in use on this computer”.
Where the result occurs
Partitions are logical containers with explicit IDs, names, user defaults, application contents, and platform enablement; operations must use the intended partition rather than assume a global namespace. In the specific case of this result, enumerate partition IDs and names, normalize the proposed name, and identify whether an existing partition is the intended target.
Evidence to collect before repair
- Collect all local partition IDs and exact names when diagnosing this result; without it the symbolic HRESULT is underdetermined.
- Record the proposed raw and normalized name.
- Preserve the create/rename operation and provisioning run identifier; it anchors the failure to the real administration object.
- Evidence should include the existing partition’s applications and user assignments, captured before a repair changes state.
Diagnostic sequence
- The next diagnostic action is to enumerate partitions through ICOMAdminCatalog2.
- To isolate it, compare normalized names and IDs.
- reuse the existing partition only when it is the intended container.
- choose a stable unique name otherwise.
- The next diagnostic action is to repeat creation/rename and verify the resulting partition ID.
Practical administration scenario
Provisioning reruns without checking existing partitions and attempts to create Production again.
Retry and recovery
Reuse/update the existing partition or choose a deliberate unique name.
Difference from nearby COMADMIN results
COMADMIN_E_AMBIGUOUS_PARTITION_NAME means a supplied name resolves non-uniquely during lookup, while this code blocks creation of a duplicate.
