SMP_REP_PHY_ERR_LOG(8) SMP_UTILS SMP_REP_PHY_ERR_LOG(8)
NAME
smp_rep_phy_err_log - invoke REPORT PHY ERROR LOG SMP function
SYNOPSIS
smp_rep_phy_err_log [--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 ERROR LOG 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 iden‐
tify a HBA (an SMP initiator) and needs the additional ,N to differen‐
tiate 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.
-z, --zero
zero the Allocated Response Length field in the request. This
option also zeros the Request Length field in the request. This
is required for strict SAS-1.1 compliance. However this option
should not be given in SAS-2 and later; if it is given an
abridged response may result.
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 ERROR LOG function was introduced in SAS-1 . The
"Expander change count" field was added in SAS-2 .
