azure-nvme-id [--debug] [--format {plain|json}] [--help | --version | --udev]

azure-nvme-id provides identification metadata in the response to Identify Namespace command for some models of NVMe devices. This is found in vendor-specific (vs) field which contains various identification details with a comma-separated, key=value format.

azure-nvme-id combines this metadata with the make and model of NVMe device namespaces to identify a device by type, name, index, etc. Output options are plain or json.

To suppoort udev rules, --udev option will invoke azure-nvme-id in udev mode.

--help

Identify NVMe namespaces:

$ sudo azure-nvme-id
/dev/nvme0n1:
/dev/nvme1n1: type=local,index=1,name=nvme-110G-1

Parse device identifiers for udev consumption:

$ sudo env DEVNAME=/dev/nvme1n1 azure-nvme-id --udev
AZURE_DISK_VS=type=local,index=1,name=nvme-110G-1
AZURE_DISK_TYPE=local
AZURE_DISK_INDEX=1
AZURE_DISK_NAME=nvme-110G-1

Check azure-nvme-id version:

$ azure-nvme-id --version
