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 identify a HBA (an SMP initiator) and needs the additional ,N to differentiate 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 hexadecimal 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 values: 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.
