The Copy command is used by the host to copy data from one or more source logical block ranges to a single consecutive destination logical block range.


-d <sdlba>, --sdlba=<sdlba>

64-bit addr of first destination logical block

-b <nlb-list,>, --blocks=<nlb-list,>

Comma separated list of the number of blocks in each range

-s <slbas,>, --slbs=<slbas,>

Comma separated list of the starting blocks in each range

--snsids=<snsids,>, -N <snsids,>

Comma separated list of the source namespace identifiers in each range

--sopts=<sopts,>, -O <sopts,>

Comma separated list of the source options in each range

-l,  --limited-retry

Sets the limited retry flag.

-f,  --force-unit-access

Set the force-unit access flag.

-p <prinfow>, --prinfow=<prinfow>

Protection Information field write definition.

-P <prinfor>, --prinfor=<prinfor>

Protection Information field read definition.

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

initial lba reference tag.

-R <reftag,>, --expected-ref-tags=<reftag,>

expected lba reference tags (comma-separated list).

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

lba app tag

-A <apptag,>, --expected-app-tags=<apptag,>

expected lba app tags (comma-separated list)

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

lba tag mask

-M <appmask,>, --expected-app-masks=<appmask,>

expected lba tag masks (comma-separated list)

-T <type>, --dir-type=<type>

Optional directive type. The nvme-cli only enforces the value be in the defined range for the directive type, though the NVMe specification (1.3a) defines only one directive, 01h, for write stream identifiers.

-S <spec>, --dir-spec=<spec>

Optional field for directive specifics. When used with write streams, this value is defined to be the write stream identifier. The nvme-cli will not validate the stream requested is within the controller’s capabilities.

-F <entry-format>, --format=<entry-format>

source range entry format

-o <fmt>, --output-format=<fmt>

Set the reporting format to normal, json or binary. Only one output format can be used at a time.

-v,  --verbose

Increase the information detail in the output.
