       smp_zoned_broadcast - invoke ZONED BROADCAST SMP function


       smp_zoned_broadcast   [--broadcast=BT]   [--expected=EX]   [--fszg=FS]   [--help]  [--hex]
       [--interface=PARAMS]   [--raw]   [--sa=SAS_ADDR]   [--szg=ZGL]   [--verbose]   [--version]


       Sends  a  SAS  Management Protocol (SMP) ZONED BROADCAST function request to a SMP target.
       The SMP target is identified by the SMP_DEVICE and the  --sa=SAS_ADDR.  Depending  on  the
       interface,  the  SAS_ADDR  may  be  deduced  from  the  SMP_DEVICE. The mpt interface uses
       SMP_DEVICE to  identify  a  HBA  (an  SMP  initiator)  and  needs  the  additional  ,N  to
       differentiate between HBAs if there are multiple present.

       This  function  requires zoning to be enabled. To send a Broadcast (Change) in the absence
       of zoning, the least intrusive way seems to be to use a PHY CONTROL request to send a link
       reset to an expander phy.  Broadcast (Change) should cause a management application client
       behind a SMP initiator port (e.g. a SAS HBA) to start a discover process.


       Mandatory arguments to long options are mandatory for short options as well.

       -b, --broadcast=BT
              BT is the broadcast type, an integer in the range 0  (default)  to  15.   Broadcast
              (Change) corresponds to 0 and will cause SMP initiators that receive it to do their
              discover process. Other known broadcast types are listed in the NOTES  section.  BT
              may  be  decimal  (default) or hexadecimal prefixed by '0x' (or '0X') or with a 'h'
              (or 'H') suffix.

       -E, --expected=EX
              set the 'expected expander change count' field in the SMP request.  The value EX is
              from  0  to 65535 inclusive with 0 being the default value. When EX is greater than
              zero then if the value doesn't match the expander change count of  the  SMP  target
              (i.e.  the  expander)  when the request arrives then the target ignores the request
              and sets a function result of "invalid expander change count" in the response.   In
              SPL-1 this field is marked as "restricted (for expected expander change count)".

       -F, --fszg=FS
              where  FS  is  the  name of a file which contains one or more source zone groups to
              send a broadcast to.  The  zone  groups  can  be  given  in  decimal  (default)  or
              hexadecimal  prefixed by '0x' (or '0X') or with a 'h' (or 'H') suffix. A zone group
              is a number in the range 0 to 255. Each zone group can be separated by space,  tab,
              comma or newline. Empty lines and those starting with "#" are ignored.

       -h, --help
              output the usage message then exit.

       -H, --hex
              output the response (less the CRC field) in hexadecimal.

       -I, --interface=PARAMS
              interface  specific parameters. In this case "interface" refers to the path through
              the operating system to the SMP initiator. See the  smp_utils  man  page  for  more

       -r, --raw
              send  the response (less the CRC field) to stdout in binary. All error messages are
              sent to stderr.

       -s, --sa=SAS_ADDR
              specifies the SAS address of the SMP target device. The mpt  interface  needs  this
              option  and  it  will  typically  be  an expander's SAS address. The SAS_ADDR is in
              decimal but most SAS addresses are shown in  hexadecimal.   To  give  a  number  in
              hexadecimal either prefix it with '0x' or put a trailing 'h' on it.

       -S, --szg=ZGL
              one  or  more source zone groups for broadcast can appear as a comma separated list
              ZGL. The may be decimal (default) or hexadecimal prefixed by '0x' (or '0X') or with
              a  'h' (or 'H') suffix. A zone group is a number in the range 0 to 255. Either this
              option or --fszg=FS (but not both) should be given.

       -v, --verbose
              increase the verbosity of the output. Can be used multiple times.

       -V, --version
              print the version string and then exit.


       The following is a list of broadcast types:
       0        Broadcast (Change)
       1        Broadcast (Reserved change 0)
       2        Broadcast (Reserved change 1)
       3        Broadcast (SES)
       4        Broadcast (Expander)
       5        Broadcast (Asynchronous event)
       6        Broadcast (Reserved 3)
       7        Broadcast (Reserved 4)
       8        Broadcast (Zone activate)

       The remaining zone types (9 to 15) may be issued by the ZONED BROADCAST function.


       The SMP ZONED BROADCAST function was introduced in SAS-2 .
