# nvme-virt-mgmt(1)

Manage flexible resources between primary and secondary controller

## NAME

nvme-virt-mgmt - Manage flexible resources between primary and secondary controller

## SYNOPSIS

```
nvme [<global-options>] virt-mgmt <device> [--cntlid=<cntlid> | -c <cntlid>]
                        [--rt=<rt> | -r <rt>] [--act=<act> | -a <act>]
                        [--nr=<nr> | -n <nr>]
```

## DESCRIPTION

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

The \<device\> 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

- \-c \<cntlid\>, --cntlid=\<cntlid\>

  Controller identifier (CNTLID)

- \-r \<rt\>, --rt=\<rt\>

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

- \-a \<act\>, --act=\<act\>

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

- \-n \<nr\>, --nr=\<nr\>

  Number of controller resources (NR)

## 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 \<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. Other versions are rejected.

- \--quiet

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

- \--set-options=\<key=value\>\[,\<key=value\>...\]

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

- \--timeout=\<ms\>

  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)](/nvme-cli.conf/5.md). A command-line flag always overrides the file.

## 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
```
