SMP_CONF_PHY_EVENT(8) SMP_UTILS SMP_CONF_PHY_EVENT(8)
NAME
smp_conf_phy_event - invoke CONFIGURE PHY EVENT function
SYNOPSIS
smp_conf_phy_event [--clear] [--enumerate] [--expected=EX]
[--file=FILE] [--help] [--hex] [--interface=PARAMS] [--pes=PES,PES...]
[--phy=ID] [--raw] [--sa=SAS_ADDR] [--thres=THR,THR...] [--verbose]
[--version] SMP_DEVICE[,N]
DESCRIPTION
Sends a SAS Serial Management Protocol (SMP) CONFIGURE PHY EVENT func‐
tion request to an SMP target. The SMP target is identified by the
SMP_DEVICE and the --sa=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 addi‐
tional ,N to differentiate between HBAs if there are multiple present.
The function request contains zero or more phy event configuration
descriptors. Each descriptor is 8 byte long and contains a phy event
source (one byte long) and optionally a peak value detector threshold
which is 32 bits long (4 bytes). These values can either be supplied on
the command line as the arguments to the --pes and --thres options, or
within a FILE given to the --file option.
Once a phy event source has been configured by this function, its coun‐
ters should be readable with the REPORT PHY EVENT or REPORT PHY EVENT
LIST functions. Peak value detector thresholds should only be non-zero
for phy event sources whose type is "peak value detector". If the
threshold value is exceeded the expander will originate a Broad‐
cast(Expander).
OPTIONS
Mandatory arguments to long options are mandatory for short options as
well.
-C, --clear
sets the CLEAR PEAKS bit the in function request. This will
cause all peak value detectors associated with this phy (i.e.
ID) to be cleared to zero.
-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.
-E, --expected=EX
set the 'expected expander change count' field in the SMP
request. The value EX is from 0 to 65535 inclusive with 0 being
the default value. When EX is greater than zero then if the
value doesn't match the expander change count of the SMP target
(i.e. the expander) when the request arrives then the target
ignores the request and sets a function result of "invalid
expander change count" in the response.
-f, --file=FILE
where FILE is a file name containing pairs of values. The first
member of each pair is a phy event source and the second member
of the pair is a peak value detector threshold. Values are
interpreted as decimal unless prefixed by '0x' or '0X' (or it
has a trailing 'h' or 'H'). Everything from and including a "#"
on a line is ignored as are blank lines. Values may be comma,
space and tab separated or appear on separate lines. This
option cannot be present with the --pes option.
-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 0).
-P, --pes=PES,PES...
where PES,PES... is a string of comma (or space) separated val‐
ues that are interpreted as phy event sources (each a value from
0 to 255). Each number is interpreted as decimal unless pre‐
fixed by '0x' or '0X' (or it has a trailing 'h' or 'H'). An
argument that contains any space separators needs to be quoted
(or otherwise escaped). When this option is given then the
--thres option may also be given and they should contain the
same number of elements in their arguments.
-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. The mpt
interface needs this option and it will typically be an
expander's SAS address. The SAS_ADDR is in decimal but most SAS
addresses are shown in hexadecimal. To give a number in hexa‐
decimal either prefix it with '0x' or put a trailing 'h' on it.
-T, --thres=THR,THR...
where THR,THR... is a string of comma (or space) separated val‐
ues that are interpreted as peak value detector thresholds (each
a 32 bit value). Each number is interpreted as decimal unless
prefixed by '0x' or '0X' (or it has a trailing 'h' or 'H'). An
argument that contains any space separators needs to be quoted
(or otherwise escaped). When this option is given then the --pes
option must also be given and they should contain the same num‐
ber of elements in their arguments.
-v, --verbose
increase the verbosity of the output. Can be used multiple
times.
-V, --version
print the version string and then exit.
