# [NAME](#NAME)

nvme-capacity-mgmt - Send capacity management command to configure/create/delete Endurance Groups or NVM Sets, returns results.

# [SYNOPSIS](#SYNOPSIS)

```
nvme [<global-options>] capacity-mgmt <device>


                        [--operation=<operation> | -O <operation>]


                        [--element-id=<element-id> | -i <element-id>]


                        [--cap-lower=<cap-lower> | -l <cap-lower>]


                        [--cap-upper=<cap-upper> | -u <cap-upper>]
```

# [DESCRIPTION](#DESCRIPTION)

For the NVMe device given, sends a capacity management command to configure/create/delete the Endurance Groups or NVM Sets with the requested operation and element\_id. On success, if the Operation is Create Endurance group or NVM Set, CQE CDW0 contains Created element identifier else CQE CDW0 is reserved.

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

# [OPTIONS](#OPTIONS)

-O &lt;operation&gt;, --operation=&lt;operation&gt;

Operation to be performed by the controller

-i &lt;element-id&gt;, --element-id=&lt;element-id&gt;

Value specific to the value of the Operation field.

-l &lt;cap-lower&gt;, --cap-lower=&lt;cap-lower&gt;

Least significant 32 bits of the capacity in bytes of the Endurance Group or NVM Set to be created

-u &lt;cap-upper&gt;, --cap-upper=&lt;cap-upper&gt;

Most significant 32 bits of the capacity in bytes of the Endurance Group or NVM Set to be created

# [GLOBAL OPTIONS](#GLOBAL_OPTIONS)

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 &lt;fmt&gt;, --output-format=&lt;fmt&gt;

Set the reporting format to *normal*, *tabular, 'json*, or *binary*. Only one output format may be used at a time.

--output-format-version=&lt;version&gt;

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=&lt;ms&gt;

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.

These options can also be set as machine-wide defaults in [nvme-cli.conf(5)](/man/os/nvme-cli/nvme-cli.conf.5). A command-line flag always overrides the file.
