SMP_CONF_ZONE_MAN_PASS(8)	    SMP_UTILS	       SMP_CONF_ZONE_MAN_PASS(8)

NAME
     smp_conf_zone_man_pass - invoke CONFIGURE ZONE MANAGER PASSWORD function

SYNOPSIS
     smp_conf_zone_man_pass [--expected=EX] [--fpass=FP] [--help] [--hex] [--in-
     terface=PARAMS]  [--new-fpass=NF]	[--new-pass=NP]  [--password=PA] [--raw]
     [--sa=SAS_ADDR] [--save=SAV] [--verbose] [--version] SMP_DEVICE[,N]

DESCRIPTION
     Sends a SAS Serial Management Protocol (SMP) CONFIGURE ZONE  MANAGER  PASS-
     WORD 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 differen-
     tiate between HBAs if there are multiple present.

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

     -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.

     -F, --fpass=FP
	    where FP is the name of a file which contains the existing password.
	    The  password  may	be in ASCII in which case it is on one line sur-
	    rounded by either single quotes are double quotes. Alternatively the
	    password may be given in ASCII hexadecimal; either	as  bytes  sepa-
	    rated by space, tab, comma or newline, or as longer strings of hexa-
	    decimal bytes in which every 2 digits represents a byte. Empty lines
	    and  those starting with "#" are ignored.  A line starting with '-1'
	    causes all remaining bytes in the password to be filled with 0xff.

     -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.

     -N, --new-fpass=NF
	    where NF is the name of a file which contains the new password.  The
	    format of this file is the same as the file given in --fpass=FP.

     -n, --new-pass=NP
	    where  NP  is  the	new  zone manager password which may be up to 32
	    bytes  long.  This	option	cannot	be  give   together   with   the
	    --new-fpass=NF option. The default password is 32 NULLs (zero bytes)
	    and  PA  is padded with NULLs to the right (to make it 32 bytes long
	    in the request).

     -P, --password=PA
	    where PA is the existing zone manager password which may be up to 32
	    bytes long. This option cannot be give together with the  --fpass=FP
	    option.  The  default  password  is  32 NULLs (zero bytes) and PA is
	    padded with NULLs to the right (to make it 32 bytes long in the  re-
	    quest).

     -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.

     -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 val-
	    ues, 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.

NOTES
     Hexadecimal bytes (or longer hexadecimal strings) should not have a leading
     "0x" or trailing "h" decoration.

     The "well known" DISABLE password is 32 bytes of 0xff. The new password can
     only be DISABLED if physical presence is supported and asserted.

CONFORMING TO
     The SMP CONFIGURE ZONE MANAGER PASSWORD function was introduced in SAS-2 .
