Ubuntu Manpage: smp_rep_phy_err_log - invoke REPORT PHY ERROR LOG SMP function

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 Serial Management Protocol (SMP) REPORT PHY ERROR LOG 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.

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 .
