NAME

       smp_conf_zone_man_pass - invoke CONFIGURE ZONE MANAGER PASSWORD function

SYNOPSIS

       smp_conf_zone_man_pass     [--expected=EX]    [--fpass=FP]    [--help]    [--hex]    [--interface=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 PASSWORD 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.

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  surrounded  by  either  single  quotes  are  double  quotes.
              Alternatively  the password may be given in ASCII hexadecimal; either as bytes separated by space,
              tab, comma or newline, or as  longer  strings  of  hexadecimal  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 request).

       -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.

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 .
