Usage

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

Overview

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.

--debug: Debug mode with additional logging.

--format {plain|json}: Output format, default is plain.

--help: Show usage information and exit.

--udev: Run in udev mode, printing a set of <key>=<value> variables consumed by udev rules. Requires DEVNAME to be set in environment.

--version: Show version information and exit.

Examples

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 azure-nvme-id 0.1.2
