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