NVME-CONFIG-SHOW(1)               NVMe Manual              NVME-CONFIG-SHOW(1)

NAME
       nvme-config-show - Show the resolved NVMe-oF INI connection
       configuration

SYNOPSIS
       nvme [<global-options>] config show
                               [--config=<file> | -J <file>]

DESCRIPTION
       Reads the NVMe-oF INI connection configuration file used by nvme
       connect-all and nvme discover, and prints every configured connection
       entry. The INI format is documented at
       https://github.com/linux-nvme/nvme-cli/blob/master/libnvme/design/CONFIG.md

       By default, the file at /etc/nvme/nvme-fabrics.conf is read. Use
       --config to show a file at a different path instead.

       In the default and tabular output formats, each entry is rendered as
       the equivalent command line that would establish it: nvme connect-all
       for a Discovery Controller entry, nvme connect for an I/O Controller
       entry, preceded by a comment naming the entry's source (which
       file/section it came from). The json output format instead reports each
       entry's fields individually (transport, address, NQN, host identity,
       and any extra connect parameters).

       This command never touches the network: addressing is shown exactly as
       configured, with no hostname resolution attempted. A persona with no
       hostnqn/hostid set is shown without those fields rather than the system
       default it would resolve to at connect time, since showing a concrete
       value here would suggest a fixed identity the configuration doesn't
       actually pin.

OPTIONS
       -J <file>, --config=<file>
           Show this INI file instead of the default
           /etc/nvme/nvme-fabrics.conf.

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
       o   Show the system's resolved configuration:

               # nvme config show

               # nvme0: Discovery Controller
               nvme connect-all --transport=tcp --traddr=192.168.1.10 --trsvcid=8009

               # nvme1: I/O Controller
               nvme connect --transport=tcp --traddr=192.168.1.10 --trsvcid=4420 \
                       --nqn=nqn.2014-08.org.nvmexpress:uuid:6a4f5e3e-...

       o   Show a configuration file at a non-default path, as JSON:

               $ nvme config show --config /tmp/nvme-fabrics.conf -o json
