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