NAME¶

smp_rep_broadcast - invoke REPORT BROADCAST SMP function

SYNOPSIS¶

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

DESCRIPTION¶

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.

OPTIONS¶

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.

NOTES¶

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.

CONFORMING TO¶
