.SH "NAME"
nvme-registry-list \- List NVMe\-oF controller ownership registry entries
.SH "SYNOPSIS"
.sp
.nf
\fInvme\fR [<global\-options>] \fIregistry list\fR
.fi
.SH "DESCRIPTION"
.sp
List all live entries in the NVMe\-oF controller ownership registry\&. The registry records which orchestrator (e\&.g\&. nvme\-stas, nbft) owns each connected NVMe\-oF controller\&. It is stored under /run/nvme/registry/ as one directory per live controller containing one plain\-text file per attribute (e\&.g\&. /run/nvme/registry/nvme3/owner)\&.
.sp
One entry is printed per live registered controller\&. Controllers with no registry entry (unowned) and non\-fabrics (PCIe) controllers (which are never registered) are not shown\&. Stale entries whose corresponding /dev/nvmeN device node no longer exists are silently skipped\&.
.SH "OPTIONS"
.SH "GLOBAL OPTIONS"
.sp
The following options are defined at the top\-level nvme command and are available to this subcommand:
.PP
\-\-dry\-run
.RS 4
Print the command that would be executed, but do not actually execute it\&.
.RE
.PP
\-\-no\-ioctl\-probing
.RS 4
Disable probing for 64\-bit IOCTL support\&.
.RE
.PP
\-\-no\-retries
.RS 4
Disable retry logic on transient errors\&.
.RE
.PP
\-o <fmt>, \-\-output\-format=<fmt>
.RS 4
Set the reporting format to
\fInormal\fR,
\fItabular, \*(Aqjson\fR, or
\fIbinary\fR\&. Only one output format may be used at a time\&.
.RE
.PP
\-\-output\-format\-version=<version>
.RS 4
Select the output format version\&. Version
\fI1\fR
uses the original field naming, while version
\fI2\fR
(default) provides more consistent and script\-friendly field names\&.
.RE
.PP
\-\-timeout=<ms>
.RS 4
Set the timeout for the command in milliseconds\&.
.RE
.PP
\-v, \-\-verbose
.RS 4
Increase the level of detail in the output\&. May be specified multiple times to further increase verbosity\&.
.RE
.sp
These options can also be set as machine\-wide defaults in nvme\-cli\&.conf(5)\&. A command\-line flag always overrides the file\&.
