NAME
smp_rep_phy_event - invoke REPORT PHY EVENT SMP function
SYNOPSIS
smp_rep_phy_event [--desc] [--enumerate] [--help] [--hex] [--inter-
face=PARAMS] [--long] [--phy=ID] [--raw] [--sa=SAS_ADDR] [--verbose]
[--version] [--zero] SMP_DEVICE[,N]
DESCRIPTION
Sends a SAS Serial Management Protocol (SMP) REPORT PHY EVENT function
request 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 a HBA (an SMP initiator) and needs the additional ,N to
differentiate between HBAs if there are multiple present.
Reports zero or more phy event descriptors. Each descriptor contains a
phy event source, a phy event (i.e. a count) and a peak value detector
theshold. At least one phy event should be maintained for each phy.
OPTIONS
Mandatory arguments to long options are mandatory for short options as
well.
-d, --desc
precede each phy event descriptor with a line announcing its
descriptor index number. Index numbers start at 1.
-e, --enumerate
enumerate all of the known Phy Event Source names, one per line
preceded by its value in hex. Ignores SMP_DEVICE if it is given;
most other options are also ignored. Exits after displaying the
names.
-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.
-l, --long
prefix each phy event source string with its numeric identifier
in hex. For example: "[0x1]: Invalid word count: 23"
-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 .
