smp_rep_phy_sata - invoke REPORT PHY SATA SMP function
smp_rep_phy_sata [--affiliation=AC] [--help]
[--hex] [--interface=PARAMS] [--phy=ID] [--raw]
[--sa=SAS_ADDR] [--verbose] [--version] [--zero]
SMP_DEVICE[,N]
Sends a SAS Serial Management Protocol (SMP) REPORT PHY SATA
request function to an 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 an 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.
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 .
