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.


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

64-bit addr of first destination logical block

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

Comma separated list of the number of blocks in each range

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

Comma separated list of the starting blocks in each range

--limited-retry, -l

Sets the limited retry flag.

--force-unit-access, -f

Set the force-unit access flag.

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

Protection Information field write definition.

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

Protection Information field read definition.

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

initial lba reference tag.

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

expected lba reference tags (comma-separated list).

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

lba app tag

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

expected lba app tags (comma-separated list)

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

lba tag mask

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

expected lba tag masks (comma-separated list)

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

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

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

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

source range entry format
