nvme-verify - Send an NVMe Verify command, return results
SYNOPSIS
--------
[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>]
[--ref-tag=<reftag> | -r <reftag>]
[--app-tag-mask=<appmask> | -m <appmask>]
[--app-tag=<apptag> | -a <apptag>]
[--storage-tag<storage-tag> | -S <storage-tag>]
[--storage-tag-check | -C]
[--output-format=<fmt> | -o <fmt>] [--verbose | -v]
[--timeout=<timeout> | -t <timeout>]
DESCRIPTION
-----------
The Verify command verifies the integrity of the stored information by
reading data and metadata.
OPTIONS
-------
-n <nsid>::
--namespace-id=<nsid>::
Namespace ID use in the command.
-s <slba>::
--start-block=<slba>::
Start block address.
-c <nlb>::
--block-count=<nlb>::
Number of logical blocks to Verify.
-l::
--limited-retry::
Sets the limited retry flag.
-f::
--force-unit-access::
Set the force-unit access flag.
-p <prinfo>::
--prinfo=<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
|=================
-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
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.
