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 Diѕcovery request will be sent to the
       specified Discovery Controller.

       See the documentation for the nvme-discover(1) command for further background.

OPTIONS

       -t <trtype>, --transport=<trtype>
           This field specifies the network fabric being used for a NVMe-over-Fabrics network.
           Current string values include:

           ┌──────┬────────────────────────────────┐
           │Value │ Definition                     │

           │rdma  │ The network fabric is an rdma  │
           │      │ network (RoCE, iWARP,          │
           │      │ Infiniband, basic rdma, etc)   │
           ├──────┼────────────────────────────────┤

           ├──────┼────────────────────────────────┤
           │tcp   │ The network fabric is a TCP/IP │

           └──────┴────────────────────────────────┘

       -a <traddr>, --traddr=<traddr>
           This field specifies the network address of the Discovery Controller. For transports
           using IP addressing (e.g. rdma) this should be an IP-based address (ex. IPv4).

       -s <trsvcid>, --trsvcid=<trsvcid>
           This field specifies the transport service id. For transports using IP addressing
           (e.g. rdma) this field is the port number. By default, the IP port number for the RDMA
           transport is 4420.

       -w <traddr>, --host-traddr=<traddr>
           This field specifies the network address used on the host to connect to the
           Controller. For TCP, this sets the source address on the socket.

       -f <iface>, --host-iface=<iface>
           This field specifies the network interface used on the host to connect to the
           Controller (e.g. IP eth1, enp2s0, enx78e7d1ea46da). This forces the connection to be
           made on a specific interface instead of letting the system decide.

       -q <hostnqn>, --hostnqn=<hostnqn>
           Overrides the default Host NQN that identifies the NVMe Host. If this option is not
           specified, the default is read from /etc/nvme/hostnqn first. 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.

       -I <hostid>, --hostid=<hostid>
           UUID(Universally Unique Identifier) to be discovered which should be formatted.

       -r <filename>, --raw=<filename>
           This field will take the output of the nvme connect-all command and dump it to a raw
           binary file. By default nvme connect-all will dump the output to stdout.

       -k <#>, --keep-alive-tmo=<#>
           Overrides the default keep alive timeout (in seconds). This option will be ignored for
           discovery, but will be passed on to the subsequent connect call.

       -c <#>, --reconnect-delay=<#>
           Overrides the default delay (in seconds) before reconnect is attempted after a connect
           loss.

       -l <#>, --ctrl-loss-tmo=<#>
           Overrides the default controller loss timeout period (in seconds).

       -g, --hdr-digest
           Generates/verifies header digest (TCP).

       -G, --data-digest
           Generates/verifies data digest (TCP).

       -i <#>, --nr-io-queues=<#>
           Overrides the default number of I/O queues create by the driver. This option will be
           ignored for discovery, but will be passed on to the subsequent connect call.

       -W <#>, --nr-write-queues=<#>
           Adds additional queues that will be used for write I/O.

       -P <#>, --nr-poll-queues=<#>
           Adds additional queues that will be used for polling latency sensitive I/O.

       -Q <#>, --queue-size=<#>
           Overrides the default number of elements in the I/O queues created by the driver. This
           option will be ignored for discovery, but will be passed on to the subsequent connect
           call.

       -m, --matching
           If a traddr was specified on the command line or in the configuration file, only
           create controllers for discovery records that match the given traddr, rather than for
           all entries in the discovery log page.

       -p, --persistent
           Don’t remove the discovery controller after retrieving the discovery log page.

       -S, --quiet
           Suppress error messages.

EXAMPLES

       •   Connect to all records returned by the Discover Controller with IP4 address
           192.168.1.3 for all resources allocated for NVMe Host name host1-rogue-nqn on the RDMA
           network. Port 4420 is used by default:

               # nvme connect-all --transport=rdma --traddr=192.168.1.3 \
               --hostnqn=host1-rogue-nqn

       •   Issue a nvme connect-all command using a /etc/nvme/discovery.conf file:

               # 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".
