.SH "NAME"
nvme-list-ctrl \- Send NVMe Identify List Controllers, return result and structure
.SH "SYNOPSIS"
.sp
.nf
\fInvme list\-ctrl\fR <device> [\-\-cntid=<cntid> | \-c <cntid>]
                        [\-\-namespace\-id=<nsid> | \-n <nsid>] [\-o <fmt> | \-\-output\-format=<fmt>]
DESCRIPTION
.fi
.sp
.nf
For the NVMe device given, sends an identify command for controller list
and provides the result and returned structure\&. This uses either mode
12h or 13h depending on the requested namespace identifier\&.

The <device> parameter is mandatory and may be either the NVMe character
device (ex: /dev/nvme0), or a namespace block device (ex: /dev/nvme0n1)\&.
The starting controller in the list always begins with 0 unless the
`\*(Aq\-\-cntid\*(Aq` option is given to override\&.

On success, the controller array is printed for each index and controller
identifier\&.

OPTIONS
.fi
.PP
\-c <cntid>, \-\-cntid=<cntid>
.RS 4
Retrieve the identify list structure starting with the given controller id\&.
.RE
.PP
\-n <nsid>, \-\-namespace\-id=<nsid>
.RS 4
If provided, will request the controllers attached to the specified namespace\&. If no namespace is given, or set to 0, the command requests the controller list for the entire subsystem, whether or not they are attached to namespace(s)\&.
.RE
.PP
\-o <format>, \-\-output\-format=<format>
.RS 4
Set the reporting format to
\fInormal\fR
or
