.SH "DESCRIPTION"
.sp
Identify NVM Command Set specific Namespace data structure for the specified LBA format index for the NVM Command Set specified in the CSI field\&.
.sp
The <device> parameter is mandatory and may be either the NVMe character device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
.sp
On success, the structure may be returned in one of several ways depending on the option flags; the structure may be parsed by the program or the raw buffer may be printed to stdout\&.
.SH "OPTIONS"
.PP
\-U <uuid\-index>, \-\-uuid\-index=<uuid\-index>
.RS 4
UUID Index of the feature
.RE
.PP
\-i <lba_format_index>, \-\-lba\-format\-index=<lba_format_index>
.RS 4
This field specifies the index into the LBA Format list identifying the LBA Format capabilities that are to be returned
.RE
.PP
\-v, \-\-verbose
.RS 4
Increase the information detail in the output\&.
.RE
.PP
\-o <format>, \-\-output\-format=<format>
.RS 4
Set the reporting format to
\fInormal\fR,
\fIjson\fR, or
\fIbinary\fR\&. Only one output format can be used at a time\&.

.nf
# nvme nvm\-id\-ns\-lba\-format /dev/nvme0 \-i 0 \-o binary > nvm_id_ns\&.raw
