                        [--ref-tag=<reftag> | -r <reftag>]
                        [--app-tag-mask=<appmask> | -m <appmask>]
                        [--app-tag=<apptag> | -a <apptag>]
                        [--storage-tag<storage-tag> | -S <storage-tag>]

```

## DESCRIPTION

The Verify command verifies the integrity of the stored information by reading data and metadata.

## OPTIONS

- \-n \<nsid\>, --namespace-id=\<nsid\>

  Namespace ID use in the command. The broadcast value 0xffffffff can also be given as *all* or *-1*.

- \-s \<slba\>, --start-block=\<slba\>

  Start block address.

- \-c \<nlb\>, --block-count=\<nlb\>

  Number of logical blocks to Verify.

- \-l, --limited-retry

  Sets the limited retry flag.

- \-f, --force-unit-access

  Set the force-unit access flag.

- \-p \<prinfo\>, --prinfo=\<prinfo\>

  Protection Information field definition.

  | | |
  | --- | --- |
  | Bit | Description |
  | 3 | PRACT: Protection Information Action. When set to 1, PI is stripped/inserted on read/write when the block format’s metadata size is 8. When set to 0, metadata is passes. |
  | 2:0 | PRCHK: Protection Information Check: |
  | 2 | Set to 1 enables checking the guard tag |
  | 1 | Set to 1 enables checking the application tag |
  | 0 | Set to 1 enables checking the reference tag |

- \-r \<reftag\>, --ref-tag=\<reftag\>

  Optional reftag when used with protection information.

- \-m \<appmask\>, --app-tag-mask=\<appmask\>

  Optional application tag mask when used with protection information.

- \-a \<apptag\>, --app-tag=\<apptag\>

  Optional application tag when used with protection information.

- \-S \<storage-tag\>, --storage-tag=\<storage-tag\>

  Variable Sized Expected Logical Block Storage Tag(ELBST).

- \-C, --storage-tag-check

  This flag enables Storage Tag field checking as part of Verify operation.

## 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.
