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]
Sends a SAS Serial Management Protocol (SMP) ZONED BROADCAST function request
to an 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 an 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.
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.
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 doesnt 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
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.
output the usage message then exit.
output the response (less the CRC field) in hexadecimal.
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 information.
send the response (less the CRC field) to stdout in binary. All error
messages are sent to stderr.
specifies the SAS address of the SMP target device. The mpt interface needs
this option and it will typically be an expanders 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.
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
increase the verbosity of the output. Can be used multiple times.
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
The SMP ZONED BROADCAST function was introduced in SAS-2 .
