SMP_REP_PHY_EVENT(8) SMP_UTILS SMP_REP_PHY_EVENT(8)NAME
smp_rep_phy_event - invoke REPORT PHY EVENT SMP function
SYNOPSIS
smp_rep_phy_event [--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 EVENT function request 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.
OPTIONS
Mandatory arguments to long options are mandatory for short options as well.
-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.
NOTES
Similar information is maintained for SAS SSP target phys (e.g. on a SAS disk). It can be obtained from the Protocol Specific Port log page
with the sg_logs utility.
Similar information may be obtained for SAS initiator phys (e.g. on a SAS HBA). As an example in Linux 2.6.28 error information can be
found in this directory /sys/class/sas_phy/phy-4:0 (for the phy 0 in SCSI/SAS host 4).
Similar information may be obtained for SATA device phys (e.g. on a SATA disk). If there is a SAT layer between OS and the SATA device then
the sg_sat_phy_event utility can fetch the information.
CONFORMING TO
The SMP REPORT PHY EVENT function was introduced in SAS-2 .
