The `rackGroupId` is an opaque operator-supplied string identifier (UUID syntax is not required) that uniquely identifies the group within the Site. Org must have an Infrastructure Provider entity. User must have authorization role with `PROVIDER_ADMIN` suffix. Alternatively, Tenant Admins with `TargetedInstanceCreation` capability can also create Expected Rack Groups if they have an account with the Site's Infrastructure Provider. Chassis identity and physical location information are conveyed via well-known label keys in `labels`: - `chassis.manufacturer`, `chassis.serial-number`, `chassis.model` - `location.region`, `location.datacenter`, `location.room`, `location.position` Reference: https://docs.nvidia.com/infra-controller/rest-api-reference/api-reference/expected-rack-group/create-expected-rack-group ## Authentication - `Authorization` header (bearer token, required) — ``` export JWT_BEARER_TOKEN="" # Example org name: "acme-inc export ORG_NAME= # Use the JWT bearer token in your API request auth header: curl -v -X GET -H "Content-Type: application/json" -H "Authorization: Bearer $JWT_BEARER_TOKEN" https://nico-rest-api.nico.svc.cluster.local/v2/org/$ORG_NAME/nico/user/current ``` ## Request ### Path parameters - `org` (string, required) — Name of the Org ### Body (application/json) This endpoint expects an ExpectedRackGroupCreateRequest. - `siteId` (string, required) — ID of the Site the Expected Rack Group belongs to - `rackGroupId` (string, required) — Operator-supplied identifier for the rack group (opaque string; UUID syntax is not required).

Rack IDs and device identity tuples must be unique across the group, with case-sensitive comparison. A provided array replaces the complete list; on PATCH, omission or null preserves it and [] clears it. On create, omission or null supplies an empty list. - `name` (string, optional, nullable) — ASCII human-readable name, at most 256 characters. An empty string is allowed. - `description` (string, optional, nullable) — Human-readable description, at most 1024 UTF-8 bytes. An empty string is allowed. - `labels` (map from string to string, optional) — User-defined key-value pairs with ASCII keys and Unicode values, each at most 255 UTF-8 bytes.
