[--namespace-id=<NUM> | -n <NUM>]
[--start-lba=<IONUM>, -s <IONUM>]

[--select-all, -a]
[--zsa=<NUM>, -z <NUM>]
[--data-len=<IONUM>, -l <IONUM>]
[--data=<FILE>, -d <FILE>]
For the NVMe device given, issues the Zone Management Send command
with the requested send action. If the send requires additional data, you
may specify the data length. If data is required, the input will default to
stdin. Alternatively, the data may come from a file that can be
specified.
-n <NUM>, --namespace-id=<NUM>
Use the provided namespace id for the command. If not
provided, the namespace id of the block device will be used. If the command is
issued to a non-block device, the parameter is required. The broadcast value
0xffffffff can also be given as all or -1.
-s <lba>, --start-lba=<lba>
The starting LBA of the zone to manage send.
-l <NUM>, --data-len=<NUM>
Send data buffer length
-O, --zsaso
Zone Send Action Specific Option
-a, --select-all
Send command to all zones
-z <NUM>, --zsa=<NUM>
Zone send action.
-l <IONUM>, --data-len=<IONUM>
Buffer length if data required
-d <FILE>, --data=<FILE>
Optional file for data (default stdin)
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). A command-line flag always overrides the file.
•Send a zone management command with action set to
1 (close zone) to namespace 1’s first zone:
# nvme zns zone-mgmt-send /dev/nvme0 -n 1 -s 0 -z 1
•Write "hello world" into the zone
descriptor for namespace 1’s first zone (requires device supports a
large enough zone extended data)
# echo "hello world" | nvme zns zone-mgmt-send /dev/nvme0 -n 1 -s 0 -z 0x10
