NAME¶
smp_rep_phy_sata - invoke REPORT PHY SATA SMP function
SYNOPSIS¶
smp_rep_phy_sata [
--affiliation=AC] [
--help]
[
--hex] [
--interface=PARAMS] [
--phy=ID] [
--raw] [
--sa=SAS_ADDR] [
--verbose] [
--version] [
--zero]
SMP_DEVICE[,N]
DESCRIPTION¶
Sends a SAS Management Protocol (SMP) REPORT PHY SATA request function to a SMP
target. The SMP target is identified by the
SMP_DEVICE and the
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.
- -a, --affiliation=AC
- where AC is the affiliation context relative
identifier that is placed in request (new in sas2r08). Defaults to 0.
- -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.
- -p, --phy=ID
- phy identifier. ID is a value between 0 and 254.
Default is 0.
- -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.
Typically this is an expander. This option may not be needed if the
SMP_DEVICE has the target's SAS address within it. 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.
- -z, --zero
- zero the Allocated Response Length field in the request.
This option also zeros the Request Length field in the request. This is
required for strict SAS-1.1 compliance. However this option should not be
given in SAS-2 and later; if it is given an abridged response may
result.
EXAMPLES¶
See "Examples" section in
http://sg.danny.cz/sg/smp_utils.html
The SMP REPORT PHY SATA function was introduced in SAS-1 . The "Expander
change count", "STP I_T nexus loss occurred" and several other
fields were added in SAS-2 .
