NAME

       smp_conf_zone_phy_info - invoke CONFIGURE ZONE PHY INFORMATION function

SYNOPSIS

       smp_conf_zone_phy_info   [--expected=EX]   [--help]   [--hex]   [--interface=PARAMS]  --pconf=FN  [--raw]
       [--sa=SAS_ADDR] [--save=SAV] [--verbose] [--version] SMP_DEVICE[,N]

DESCRIPTION

       Sends a SAS Serial Management Protocol (SMP) CONFIGURE ZONE PHY INFORMATION 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.

       Each  zone  phy  configuration descriptor is 4 bytes long. The first byte is a (expander) phy identifier.
       The second byte has 3 modifiable bits: bit 5 is "inside ZPSDS persistent"; bit  4  is  "requested  inside
       ZPSDS";  and  bit 2 is "zone group persistent". The other bits in the second byte are reserved and should
       be 0. The third byte is reserved and should be 0. The fourth byte is the zone group.

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.

       -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.

       -p, --pconf=FN
              FN  is  a file containing zone phy configuration descriptors 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.  Since each
              zone phy configuration descriptor is 4 bytes long, the number of bytes in FN is expected to  be  a
              multiple of 4.

       -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

       The expander phys that make up a wide port (2 or more attached to phys with the same SAS address) must be
       set to the same zone phy configuration settings (other than the phy id).

       Zone  phy  information  can be read back from an expander and placed in a file with the smp_discover_list
       utility's --zpi=FN option. The format of that file should  be  suitable  for  this  utility's  --pconf=FN
       option.

CONFORMING TO

       The SMP CONFIGURE ZONE PHY INFORMATION function was introduced in SAS-2 .
