SMP_REP_PHY_EVENT_LIST(8) SMP_UTILS SMP_REP_PHY_EVENT_LIST(8)
NAME
smp_rep_phy_event_list - invoke REPORT PHY EVENT LIST SMP function
SYNOPSIS
smp_rep_phy_event_list [--desc] [--enumerate] [--force] [--help]
[--hex] [--index=IN] [--interface=PARAMS] [--long] [--nonz] [--raw]
[--sa=SAS_ADDR] [--verbose] [--version] [--zero] SMP_DEVICE[,N]
DESCRIPTION
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 con‐
tains 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.
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.
-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.
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 LIST function was introduced in SAS-2 .
