# nvme-exclusion-add(1) Manual Page

## NAME

nvme-exclusion-add - Add an entry to an NVMe-oF exclusion list

## SYNOPSIS

    nvme [<global-options>] exclusion add [--name=<NAME> | -N <NAME>]
                            --entry=<ENTRY> | -e <ENTRY>

## DESCRIPTION

Append an entry to the NVMe-oF exclusion list named <NAME>, creating the list if it does not exist. The entry is a semicolon-separated list of key=value fields; a controller is excluded when it matches every field present in the entry.

The recognized field keys are the nvme connect option names: transport, traddr, trsvcid, nqn, host-traddr, host-iface, hostnqn and hostid. Only the fields given are matched, so a single key excludes broadly and more keys narrow the match. See the exclusion list overview (EXCLUSIONS.md) for the full match semantics.

The entry is validated before it is written; an entry with an unknown key, or with no recognized field, is rejected. This command requires root.

## OPTIONS

-N <NAME>
--name=<NAME>

  Name of the exclusion list to add to. Omit to add to the default list (/etc/nvme/exclusions.conf).

-e <ENTRY>
--entry=<ENTRY>

  The entry to add, e.g. "transport=tcp;traddr=192.0.2.10;nqn=…".

## 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.

--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.

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

## EXAMPLES

- Exclude a single path to a subsystem:

      # nvme exclusion add --name user \
              --entry "transport=tcp;traddr=192.0.2.10;trsvcid=4420;nqn=nqn.2024-01.com.example:vol1"

- Exclude a whole subsystem on every transport and address:

      # nvme exclusion add --name user --entry "nqn=nqn.2024-01.com.example:retired"
