# [DESCRIPTION](#DESCRIPTION)

Manage flexible resources between primary and secondary controller, return results.

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

On success it returns 0, error code otherwise.

# [OPTIONS](#OPTIONS)

-c &lt;cntlid&gt;, --cntlid=&lt;cntlid&gt;

Controller identifier (CNTLID)

-r &lt;rt&gt;, --rt=&lt;rt&gt;

Resource Type (RT): \[0,1] 0h: VQ Resources 1h: VI Resources

-a &lt;act&gt;, --act=&lt;act&gt;

Action(ACT): \[1,7,8,9] 1h: Primary Flexible 7h: Secondary Offline 8h: Secondary Assign 9h: Secondary Online

-n &lt;nr&gt;, --nr=&lt;nr&gt;

Number of controller [resources (NR)](/man/os/nvme-cli/resources.NR)

# [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. Other versions are rejected.

--quiet

Suppress informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level.

--set-options=&lt;key=value&gt;\[,&lt;key=value&gt;...]

Set libnvme library options for this invocation. Supported keys are *force-4k*, *mi-probe-enabled*, *test-base-dir* and *test-sysfs-dir*.

--timeout=&lt;ms&gt;

Set the timeout for the command in milliseconds. *infinite* or *-1* waits without a time limit (0xffffffff).

-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.

# [EXAMPLES](#EXAMPLES)

•Has the program issue a virt-mgmt to manage flexible resources.

```
# nvme virt-mgmt /dev/nvme0 -c 0 -r 1 -a 1 -n 0
```
