invoke REPORT BROADCAST SMP function


smp_rep_broadcast [--broadcast=BT] [--help] [--hex] [--interface=PARAMS] [--raw] [--sa=SAS_ADDR] [--verbose] [--version] SMP_DEVICE[,N]


Sends a SAS Serial Management Protocol (SMP) REPORT 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.


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. 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.

-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 information.

-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.

-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.
