NAME

       smp_zone_unlock - invoke ZONE UNLOCK SMP function

SYNOPSIS

       smp_zone_unlock    [--activate]    [--expected=EX]    [--help]   [--hex]   [--interface=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 either each zone group whose zone
       permission table entries or zone phy information 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 ACTIVATED 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 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.

       -v, --verbose
              increase the verbosity of the output. Can be used multiple times.

       -V, --version
              print the version string and then exit.
