+DESCRIPTION
+-----------
+The Verify command verifies the integrity of the stored information by
+reading data and metadata.
+
+OPTIONS
+-------
+--namespace-id=<nsid>::
+-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.
+
+--force-unit-access::

++
+[]
+|=================
+|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
+|=================
+
+--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.
+
+--storage-tag-check=<storage-tag-check>::
+-C <storage-tag-check>::
+ This bit specifies the Storage Tag field shall be checked as part of Verify operation.
