REST currently uses Flow table UUIDs for rack and tray resources while related APIs use inventory identifiers. Exposing multiple identifiers for the same resources makes ID semantics confusing and inconsistent across REST APIs.

This change standardizes rack and tray identifiers at the REST boundary:

  • rack id and rackId values use the rack inventory identifier
  • compute tray id values use the machine identifier
  • NVSwitch tray id values use the switch identifier
  • GET /tray/{id} accepts either a component inventory identifier or its BMC MAC address

Flow carries external inventory identifiers explicitly in inventory responses. Rack operation targets use the new RackTarget.external_id oneof branch, while RackTarget.id remains available for internal UUID-based Flow targeting. REST-facing lookup RPCs resolve only external identifiers and do not fall back to Flow table UUIDs.

The REST models, handlers, OpenAPI specification, generated SDK, and published documentation use the same contract. REST component resources use id consistently; the duplicate componentId and componentIds fields and parameters are removed.

Component inventory identifiers are unique only within a component type. Typed operation targets preserve their component type through slot resolution. An untyped lookup that matches more than one component returns 412 Precondition Failed instead of selecting one; clients can use the BMC MAC address for GET /tray/{id}. Missing validation diffs use macAddress to identify the component and return id: null rather than exposing a Flow UUID.

Historical operation-run targets resolve rack identifiers from rack rows that still exist, including soft-deleted rows. If the rack was purged or has no external ID, the request fails explicitly. No data migration is added.

Type of Change

  • Add - New feature or capability
  • Change - Changes in existing functionality
  • Fix - Bug fixes
  • Remove - Removed features or deprecated functionality
  • Internal - Internal changes (refactoring, tests, docs, etc.)

Breaking Changes

  • This PR contains breaking changes

Rack and tray identifiers in REST requests and responses are no longer Flow table UUIDs. Clients that persist or validate these identifiers as UUIDs must use the returned inventory identifiers instead; requests using the former Flow UUIDs no longer resolve. The componentId and componentIds REST aliases are removed in favor of id and ids. Tray lookup also accepts a component BMC MAC address.

The intentional REST contract changes are recorded in the repository oasdiff allowlist. The Flow protobuf changes are additive: RackTarget.external_id uses field number 4, and ComponentDiff.component_mac_address uses field number 7; existing field numbers are unchanged.

Testing

  • Unit tests added/updated
  • Integration tests added/updated
  • Manual testing performed
  • No testing required (docs, internal refactor, etc.)

Summary by CodeRabbit

  • New Features

    • Rack and tray operations now support public rack and component identifiers.
    • Components can be identified by public ID or BMC MAC address, with optional type disambiguation.
    • Operation results include the associated rack’s external identifier.
    • Missing component details include MAC address information.
  • Bug Fixes

    • Ambiguous or unresolved identifiers now return clearer errors.
    • Disk targets reject partition paths and accept only whole-disk devices.
  • Documentation

    • Updated API documentation, schemas, examples, and query parameters to use generic identifiers.

Walkthrough

The REST and Flow APIs now use Core rack and component identifiers at the API boundary. Flow UUIDs remain internal. Rack and tray lookup, task filtering, operation targets, models, inventory resolution, tests, and API documentation were updated.

Changes

Core identifier migration

Layer / File(s) Summary
Identifier contracts and conversion
rest-api/flow/proto/..., rest-api/flow/internal/converter/..., rest-api/flow/pkg/...
Flow contracts and converters expose external rack and component identifiers. Untyped component references are accepted when identifiers are unambiguous.
Inventory lookup and Flow resolution
rest-api/flow/internal/inventory/..., rest-api/flow/internal/service/..., rest-api/flow/internal/task/...
Flow resolves racks by external ID and components by external ID or BMC MAC. Shared resolution reports not-found and ambiguous matches with typed errors. Operation runs map internal rack UUIDs to external rack IDs, including soft-deleted racks.
REST request routing
rest-api/api/pkg/api/handler/...
Rack and tray operations construct Flow requests with external identifiers. Task handlers use generic rack and component identifiers. Workflow calls pass raw workflow ID strings.
REST models, validation, and API schema
rest-api/api/pkg/api/model/..., rest-api/api/pkg/api/handler/*_test.go, rest-api/openapi/...
REST models use direct external identifiers, remove duplicate component fields, accept component IDs or MAC addresses, and document ambiguity responses and updated disk-target rules.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 00410

This change moves rack and tray APIs to public inventory identifiers, but unresolved identifier-conversion and typed lookup behavior could cause requests to lose identifiers or fail for duplicate component IDs. These issues should be resolved before merge.

P1 Badge Include a component type in external tray targets

When an id filter is provided, this constructs an ExternalRef with the ID but leaves its type at COMPONENT_TYPE_UNKNOWN. Flow passes every operation target through ComponentTargetFrom, which rejects unknown external component types, so tray validation, power, and firmware operations using the newly advertised Core IDs fail before inventory resolution; the same type-less shape is used by the single-tray and slot-resolved handlers. Either resolve the ID to a typed target first or add an untyped, ambiguity-checked Core-ID target form.

Fixed. Typed tray operations now propagate the component type. Untyped single-tray lookups are resolved by external component ID or BMC MAC and return 412 Precondition Failed when an external ID is ambiguous.

Before we move forward with the review:

  • Are the Rack IDs coming from RMS? Then there's no reason to highlight them as Core ID. It should be considered the unique identifier used across all of NICo. In descriptions we should say Unique identifier for Rack within NICo
  • Are these Rack/Component IDs string names?
  • id and componentId seems confusing. Can we remove one of them?
  • We don't want gRPC details leaking in REST e.g. core.rack.rack_id

@thossain-nv Thanks — I agree.

  1. It comes from core not rms. Describing it as Unique identifier for the Rack within NICo.
  2. Rack and Component IDs are opaque strings, not resource names, and REST does not require UUID formatting.
  3. Agree, cleaned up.

P1 Badge Add type disambiguation to single-tray targets

When Compute and NVSwitch/PowerShelf components share the same external ID—a case the new batch API explicitly supports via its type filter—this single-tray request sends an ExternalRef with COMPONENT_TYPE_UNKNOWN, while the route exposes no type selector. Flow's newly added len(matches) > 1 ambiguity branch is fresh evidence that validation, power, firmware, task listing, and GET requests for either tray will now fail rather than resolve, so the single-resource contract needs a type discriminator or a globally unique public identifier.

@thossain-nv It correctly identifies the ambiguity, but the resulting behavior is intentional. The endpoint accepts either the component ID or a BMC MAC address. Because an external ID is only unique together with the component type, an untyped ambiguous lookup returns 412 Precondition Failed; the caller can use the component MAC address to identify the tray unambiguously.

P2 Badge Retain an identifier for missing-component diffs

For every missing_in_actual drift, the producer deliberately sets the internal component UUID but leaves ExternalID nil; this assignment now discards that UUID and converts the absent external ID to "". Consequently the normal validation result for an expected-but-undiscovered component emits id: "", contradicting the newly required OpenAPI ComponentDiff.id field and leaving operators unable to identify which expected component is missing.

P2 Badge Preserve rack IDs on historical run targets

After a rack is soft-deleted, GetRacksByIDs excludes it even though operation_run_target rows retain their independent rack_id; the map lookup here therefore assigns an empty RackExternalId. Because the REST converter now replaces the persisted UUID with only this field, listing historical targets returns the required rackId as an empty string. Persist the public ID with the target or include deleted racks during enrichment.

Preserve the selected component type after slot resolution.

componentTargetSpecFromIDs creates an untyped ExternalRef. A request with slotId and type=Compute uses the type during resolution, then drops it before the validation, power, or firmware workflow starts. If the same public ID exists for another component type, Flow rejects the later untyped target as ambiguous.

Pass the selected type into this helper and set ExternalRef.Type. Add a duplicate-ID regression test for typed slot filtering.

Should mock Component still have UUID as identifier?

Yes. The UUID remains the Flow-internal identity of the mock component. The REST converter maps the protobuf component_id to the REST id field and does not expose the internal UUID.

This should still say ID of the Rack to be consistent with other descriptions for path params.

Fixed in a56548cff. The rack path parameter descriptions now consistently use ID of the Rack.

Identifier: &flowv1.ComponentTarget_Id{
Id: &flowv1.UUID{Id: trayStrID},
},
Identifier: &flowv1.ComponentTarget_External{External: &flowv1.ExternalRef{Id: trayStrID}},

134-166: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Map pb.Rack.ExternalId in RackFrom. CreateExpectedRack and PatchRack pass requests through RackFrom before persistence. RackFrom does not copy r.GetExternalId() into rack.Rack.ExternalID, so writes with a public identifier store an empty identifier. External-ID lookups then cannot find the rack. Set ExternalID from r.GetExternalId() in RackFrom.
