DESCRIPTION¶
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 Discovery request will be sent to the specified Discovery Controller.
See the documentation for the nvme-discover(1) command for further background.

EXAMPLES¶
# nvme connect-all --transport=rdma --traddr=192.168.1.3 \ --hostnqn=host1-rogue-nqn
# nvme connect-all --nbft
# nvme connet-all --nbft-path=/sys/firmware/acpi/tables/NBFT1
# Machine default 'nvme discover' commands. Query the # Discovery Controller's two ports (some resources may only # be accessible on a single port). Note an official # nqn (Host) name defined in the NVMe specification is being used # in this example. -t rdma -a 192.168.69.33 -s 4420 -q nqn.2014-08.com.example:nvme:nvm-subsystem-sn-d78432 -t rdma -a 192.168.1.4 -s 4420 -q nqn.2014-08.com.example:nvme:nvm-subsystem-sn-d78432 At the prompt type "nvme connect-all".
