-n <nsid>::
	Namespace ID use in the command.

--start-block=<slba>::
-s <slba>::
	Start block address.

--block-count=<nlb>::
-c <nlb>::
	Number of logical blocks to Verify.

--limited-retry::
-l::
	Sets the limited retry flag.

metadata is passes.
|2:0|PRCHK: Protection Information Check:
|2|Set to 1 enables checking the guard tag
|1|Set to 1 enables checking the application tag
|0|Set to 1 enables checking the reference tag
|=================

--ref-tag=<reftag>::
-r <reftag>::
	Optional reftag when used with protection information.

--app-tag-mask=<appmask>::
-m <appmask>::
	Optional application tag mask when used with protection information.

--app-tag=<apptag>::
-a <apptag>::
	Optional application tag when used with protection information.

--storage-tag=<storage-tag>::
-S <storage-tag>::
	Variable Sized Expected Logical Block Storage Tag(ELBST) and Expected Logical
	Block Reference Tag (ELBRT), CDW2 and CDW3 (00:47) bits.
