Hi Andrey,
Do you mean on the host (initiator) side, bdev/nvme? When you are connecting to a NVMe-oF target with the NVMe bdev (either via the [Nvme] configuration file section or the construct_nvme_bdev RPC method), you are specifying the address to a subsystem, and all namespaces in that subsystem will be exposed as bdevs. There is currently no way to specify just a single namespace within the subsystem, but we could probably add this if there is a reasonable use case that requires it.
If you are talking about the target side, you can configure namespaces to have a particular ID using the optional second parameter to the Namespace line in the [SubsystemN] config sections, or via the optional namespace.nsid parameter to the nvmf_subsystem_add_ns RPC method.
Thanks,
-- Daniel
