[--sa=SAS_ADDR] [--verbose] [--version] [--zero]
SMP_DEVICE[,N]
Sends a SAS Serial Management Protocol (SMP) REPORT PHY EVENT LIST
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 list descriptors. Each descriptor
contains a phy identifier, 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.
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.
- -f, --force
- force the report to continue after the last descriptor index has been
exceeded. The default action is too stop the report when the last
descriptor index has been exceeded. at 1.
- -h, --help
- output the usage message then exit.
- -H, --hex
- output the response (less the CRC field) in hexadecimal.
- -i,
--index=IN
- starting phy event list descriptor index. IN is a value between 0
and 65535. The default is 1. If IN is 0 then the response should
contain no phy event list descriptors but the 'last phy event list
descriptor index' and 'phy event list descriptor length' fields in the
response should be set appropriately. The last point was clarified in
SPL-2 revision 3.
- -l, --long
- prefix each phy event source string with its numeric identifier in hex.
Also place "phy_id=" in front of the phy identifier number. For
example: "phy_id=3: [0x1]: Invalid word count: 29"; without this
option this line would be: "3: Invalid word count: 29".
- -n, --nonz
- only show phy events with non-zero counts or peak values. The default is
to show all phy events in the response.
- -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.
- -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.
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.
The SMP REPORT PHY EVENT LIST function was introduced in SAS-2
.
