stafctl - STorage Appliance Finder (STAF) utility program

       The following commands are understood:

       tron
           Trace ON. Enable code tracing, which is to say that lots of debug information will be printed to the
           syslog (e.g. systemd-journal).

       troff
           Trace OFF. Disable code tracing.

       status
           Show runtime status information.

       ls
           Show the list of discovery controllers. This will list all the controllers configured in
           stafd.conf(5) as well as those discovered with mDNS service discovery.

       dlp
           Show discovery log pages.

       adlp
           Show all discovery log pages.

stafctl is a tool that can be used to communicate with the stafd(8) daemon to retrieve operational data.

Example1.Listallthediscoverycontrollers

           $ stafctl ls
           [{'device':      'nvme0',
             'host-iface':  '',
             'host-traddr': '',

             'traddr':      '::1',
             'transport':   'tcp',
             'trsvcid':     '8009'}]

       Example2.Enabletracing

           $ stafctl tron

       Example3.Showdiscoverylogpagesfromaspecificdiscoverycontroller

           $ stafctl dlp --transport tcp --traddr ::1 --trsvcid 8009

             'trsvcid': '8009',

       On success, 0 is returned; otherwise, a non-zero failure code is returned.

       stafctl - STorage Appliance Finder (STAF) utility program

       The following options are understood:

       -h, --help
           Print the help text and exit.

       --version
           Print the version string and exit.

       -d, --detailed
           Print additional details.

       -tTRTYPE, --transport=TRTYPE
           NVMe-over-Fabrics fabric type (default: "tcp").

       -aTRADDR, --traddr=TRADDR
           Discovery controller's network address.

       -sTRSVCID, --trsvcid=TRSVCID
           Transport service id (for IP addressing, e.g. tcp, rdma, this field is the port number).

       -wTRADDR, --host-traddr=TRADDR
           Network source address used on the host to connect to the controller.

       -fIFACE, --host-iface=IFACE
           This field specifies the network interface used on the host to connect to the controller.

       -nNQN, --nqn=NQN
           This field specifies the Controller's NVMe Qualified Name.

           This field is mandatory for I/O Controllers, but is optional for Discovery Controllers (DC). For the
           latter, the NQN will default to the well-known DC NQN: nqn.2014-08.org.nvmexpress.discovery if left
           undefined.
