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 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 .
