SYNOPSIS

nvme [<global-options>] zns id-ctrl <device>

For the NVMe device given, sends the zoned command set’s identify controller command and provides the result and returned structure.

The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1).

On success, the data structure returned by the device will be decoded and displayed in one of several ways.

The following options are defined at the top-level nvme command and are available to this subcommand:

--dry-run: Print the command that would be executed, but do not actually execute it.
--no-ioctl-probing: Disable probing for 64-bit IOCTL support.
--no-retries: Disable retry logic on transient errors.
-o <fmt>
--output-format=<fmt>: Set the reporting format to normal, tabular, 'json, or binary. Only one output format may be used at a time.
--output-format-version=<version>: Select the output format version. Version 1 uses the original field naming, while version 2 (default) provides more consistent and script-friendly field names.
--timeout=<ms>: Set the timeout for the command in milliseconds.
-v
--verbose: Increase the level of detail in the output. May be specified multiple times to further increase verbosity.

Has the program interpret the returned buffer and display the known fields in a human readable format:
```
# nvme zns id-ctrl /dev/nvme0
```
Show the output in json format
```
# nvme zns id-ctrl /dev/nvme0 -o json
```
