NAME

       sas_phy_free - free a SAS PHY

SYNOPSIS

       void sas_phy_free(struct sas_phy * phy);

ARGUMENTS

       phy
	   SAS PHY to free

DESCRIPTION

       Frees the specified SAS PHY.

NOTE

       This function must only be called on a PHY that has not successfully been added using sas_phy_add.

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] SMP_DEVICE[,N]

DESCRIPTION

       Sends a SAS Management Protocol (SMP) REPORT PHY ERROR LOG request function 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. With one interface there is  one	SMP_DEVICE
       per machine so the SMP_DEVICE,N syntax is needed 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 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 127. Default is 0.

       -r, --raw
	      send the response 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 ERROR LOG function was introduced in SAS-1 .	The "Expander change count" field was added in SAS-2 .
