SMP_ZONE_UNLOCK(8)		    SMP_UTILS		      SMP_ZONE_UNLOCK(8)

NAME
     smp_zone_unlock - invoke ZONE UNLOCK SMP function

SYNOPSIS
     smp_zone_unlock  [--activate]  [--expected=EX]  [--help]  [--hex] [--inter-
     face=PARAMS] [--raw] [--sa=SAS_ADDR] [--verbose] [--version] SMP_DEVICE[,N]

DESCRIPTION
     Sends a SAS Serial Management Protocol (SMP) ZONE UNLOCK  function  request
     to  an  SMP  target. The SMP target is identified by the SMP_DEVICE and the
     --sa=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.

     If  this  function is successful then a Broadcast (Change) is sent from ei-
     ther each zone group whose zone permission table entries or zone phy infor-
     mation has changed; or from zone group 1. Broadcast (Change) should cause a
     management application client behind an SMP initiator port (e.g. a SAS HBA)
     to start a discover process.

OPTIONS
     Mandatory arguments to long options are  mandatory  for  short  options  as
     well.

     -a, --activate
	    sets  the  ACTIVATE REQUIRED bit in the function request. When it is
	    set the function call will fail with a function result of NOT  ACTI-
	    VATED if the expander has not "processed the activate step".

     -E, --expected=EX
	    set  the  'expected expander change count' field in the SMP request.
	    The value EX is from 0 to 65535 inclusive with 0 being  the  default
	    value.  When EX is greater than zero then if the value doesn't match
	    the expander change count of the SMP target (i.e. the expander) when
	    the request arrives then the target ignores the request and  sets  a
	    function result of "invalid expander change count" in the response.

     -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.

     -r, --raw
	    send  the response (less the CRC field) to stdout in binary. All er-
	    ror messages are sent to stderr.

     -s, --sa=SAS_ADDR
	    specifies the SAS address of the SMP target device. The  mpt  inter-
	    face  needs  this  option and it will typically be an expander's SAS
	    address. 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.

CONFORMING TO
     The SMP ZONE UNLOCK function was introduced in SAS-2 .
