+.SH "DESCRIPTION"
+.sp
+Send one or more Discovery requests to a NVMe over Fabrics Discovery Controller, and create controllers for the returned discovery records\&.
+.sp
+If no parameters are given, then \fInvme connect\-all\fR will attempt to find a /usr/local/etc/nvme/discovery\&.conf file to use to supply a list of connect\-all commands to run\&. If no /usr/local/etc/nvme/discovery\&.conf file exists, the command will quit with an error\&.
+.sp
+Otherwise a specific Discovery Controller should be specified using the \-\-transport, \-\-traddr and if necessary the \-\-trsvcid and a Discovery request will be sent to the specified Discovery Controller\&.
+.sp
+See the documentation for the nvme\-discover(1) command for further background\&.

If that does not exist, the autogenerated NQN value from the NVMe Host kernel module is used next\&. The Host NQN uniquely identifies the NVMe Host, and may be used by the the Discovery Controller to control what NVMe Target resources are allocated to the NVMe Host for a connection\&.
