[verse]
'nvme-verify' <device> [--namespace-id=<nsid> | -n <nsid>]
[--start-block=<slba> | -s <slba>]
[--block-count=<nlb> | -c <nlb>]
[--limited-retry | -l]
[--force-unit-access | -f]
[--prinfo=<prinfo> | -p <prinfo>]

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::
-f::
Set the force-unit access flag.
--prinfo=<prinfo>::
-p <prinfo>::
Protection Information field definition.
+
[]
|=================
|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.
