InfiniBand PKey Creation | NVIDIA Switch Infrastructure

Provisions a new InfiniBand Partition Key (PKey) on UFM and records it in Nautobot. The PKey is the IB fabric’s per-tenant isolation primitive. Members are attached separately through the IB PKey Member Add workflow.

For details on Partition Key creation, see the InfiniBand PKey Creation user guide.

The workflow is idempotent on the canonical PKey value. Re-running with the same PKey returns the existing record rather than allocating a duplicate.
