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_event_list - invoke REPORT PHY EVENT LIST SMP function

SYNOPSIS

       smp_rep_phy_event_list  [--help]  [--hex]  [--index=IN]	[--interface=PARAMS]  [--raw]  [--sa=SAS_ADDR]	[--verbose]  [--version]  [--zero]
       SMP_DEVICE[,N]

DESCRIPTION

       Sends a SAS Management Protocol (SMP) REPORT PHY EVENT LIST 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 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, --index=IN
	      starting phy event list descriptor index. ID is a value between 1 and 65535. Default is 1.

       -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.

       -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.

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 EVENT LIST function was introduced in SAS-2 .
