nvme-log-host-discovery(1)

Usage

nvme [<global-options>] log host-discovery <device> [{--all-host-entries | -a}] [{--rae | -r}]

Retrieve Host Discovery Log, show it

The <device> parameter is mandatory NVMe MI device supported by the discovery controller (ex: mctp:<net>,<eid>[:ctrl-id]).

On success it returns 0, error code otherwise.

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.

-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). A command-line flag always overrides the file.
