NAME
       nvme-dsm	- Send NVMe Data Set Management, return	results

SYNOPSIS
       nvme dsm	<device> [--namespace-id=<nsid>	| -n <nsid>]
			       [--ctx-attrs=<attribute-list,> |	-a <attribute-list,>]
			       [--blocks=<nlb-list,> | -b <nlb-list,>]
			       [--slbs=<slba-list,> | -s <slba-list,>]
			       [--ad=<deallocate> | -d <deallocate>]
			       [--idw=<write> |	-w <write>] [--idr=<read> | -r <read>]
			       [--cdw11=<cdw11>	| -c <cdw11>]
			       [--output-format=<fmt> |	-o <fmt>] [--verbose | -v]
			       [--timeout=<timeout> | -t <timeout>]

DESCRIPTION
       For the NVMe device given, sends	a Data Set Management command and
       provides	the result and returned	structure.

       The <device> parameter is mandatory and may be either the NVMe
       character device	(ex: /dev/nvme0), or a namespace block device (ex:
       /dev/nvme0n1). If the character device is given,	the '--namespace-id'
       option is mandatory, otherwise it will use the ns-id of the namespace
       for the block device you	opened.	For block devices, the ns-id used can
       be overridden with the same option.

       You must	specify	at least one of	the values for range list. If the
       range lists provided do not list	the same number	of elements, the
       default values for the remaining	in the range will be set to 0.

       The command dword 11 may	be provided at the command line. For
       convenience, the	current	defined	attributes (discard, integral
       read/write) for a data-set management have flags. If cdw11 is
       specified, this will override any settings from the flags may have
       provided.

OPTIONS
       -n <nsid>, --namespace-id=<nsid>
	   Sends the command with the requested	nsid. This is required for the
	   character devices, or overrides the block nsid if given.

       -a <attribute-list,>, --ctx-attrs=<attribute-list>
	   Comma separated list	of the context attributes in each range

       -b <nlb-list,>, --blocks=<nlb-list,>
	   Comma separated list	of the number of blocks	in each	range

       -s <slba-list,>,	--slbs=<slba-list,>
	   Comma separated list	of the starting	block in each range

       -d <deallocate>,	--ad=<deallocate>
	   Attribute Deallocate.

       -w <write>, --idw=<write>
	   Attribute Integral Dataset for Write.

       -r <read>, --idr=<read>
	   Attribute Integral Dataset for Read.

       -c <cdw11>, --cdw11=<cdw11>
	   All the command command dword 11 attributes.	Use exclusive from
	   specifying individual attributes

       -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.

       -t <timeout>, --timeout=<timeout>
	   Override default timeout value. In milliseconds.
