	Start block address.

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

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

|Bit|Description
|3|PRACT: Protection Information Action. When set to 1, PI is stripped/inserted
on read/write when the block format's metadata size is 8. When set to 0,
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
|=================

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

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

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

-S <storage-tag>::
--storage-tag=<storage-tag>::
	Variable Sized Expected Logical Block Storage Tag(ELBST).

-C::
--storage-tag-check::
	This flag enables Storage Tag field checking as part of Verify operation.

-o <fmt>::
--output-format=<fmt>::
	Set the reporting format to 'normal', 'json' or 'binary'. Only one
