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 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.

Examples

See "Examples" section in http://sg.danny.cz/sg/smp_utils.html

Conforming To

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 .
