SMP_ENA_DIS_ZONING(8)		   SMP_UTILS		 SMP_ENA_DIS_ZONING(8)

NAME
       smp_ena_dis_zoning - invoke ENABLE DISABLE ZONING SMP function

SYNOPSIS
       smp_ena_dis_zoning  [--disable] [--ena-dis=ED] [--expected=EX] [--help]
       [--hex]	[--interface=PARAMS]  [--raw]	[--sa=SAS_ADDR]	  [--save=SAV]
       [--verbose] [--version] SMP_DEVICE[,N]

DESCRIPTION
       Sends  a	 SAS  Management Protocol (SMP) ENABLE DISABLE ZONING function
       request to a 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 iden‐
       tify  a HBA (an SMP initiator) and needs the additional ,N to differen‐
       tiate between HBAs if there are multiple present.

       If neither --disable nor --ena-dis=ED options  are  given  then	enable
       zoning (i.e. "--ena-dis=1") is assumed.

       This  function  does not change the state of the current zoning enabled
       flag (as seen in the REPORT GENERAL response). Such a state change will
       occur on a subsequent invocation of the ZONE ACTIVATE function.

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

       -d, --disable
	      set the 'enable disable zoning' field in the SMP	request	 to  2
	      which will disable zoning.

       -e, --ena-dis=ED
	      set the 'enable disable zoning' field in the SMP request. ED may
	      take these  values:  0  for  no  change,	1  for	enable	zoning
	      (default)	 and  2	 for  disable  zoning.	If this option and the
	      --disable option are both given then they cannot contradict  one
	      another.

       -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
	      error messages are sent to stderr.

       -s, --sa=SAS_ADDR
	      specifies the SAS address of the	SMP  target  device.  The  mpt
	      interface	 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 hexa‐
	      decimal either prefix it with '0x' or put a trailing 'h' on it.

       -S, --save=SAV
	      set the 'save' field in the SMP request. SAV may take these val‐
	      ues:  0 for updating the shadow values (default), 1 for updating
	      the saved values, 2 for updating shadow values and if  available
	      the saved values, 3 for updating both saved and shadow values.

       -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 ENABLE DISABLE ZONING function was introduced in SAS-2 .
