.SH "DESCRIPTION"
.sp
For the NVMe device given, send an nvme Get LBA Status admin command and provides the results\&.
.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 returned get lba data structure may be returned in one of several ways depending on the option flags; the structure may parsed by the program and printed in a readable format or the raw buffer may be printed to stdout for another program to parse\&.
.SH "OPTIONS"
.PP
\-n <nsid>, \-\-namespace\-id=<nsid>
.RS 4
Send the Get LBA Status command for the specified nsid\&. This can be used to override the default value for either character device (unspecified) or the block device (result from NVME_IOCTL_ID)\&.
.RE
.PP
\-s <slba>, \-\-start\-lba=<slba>
.RS 4

.RS 4
Maximum Number of Dwords(MNDW) specifies maximum number of dwords to return
.RE
.PP
\-a <action\-type>, \-\-action=<action\-type>
.RS 4
Action Type(ATYPE) specifies the mechanism it uses in determining the LBA Status Descriptors\&.
.RE

.RS 4
Range Length(RL) specifies the length of the range of contiguous LBAs beginning at SLBA
.RE
.PP
\-t <timeout>, \-\-timeout=<timeout>
.RS 4
Override default timeout value\&. In milliseconds\&.
.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\&.
