Ubuntu Manpage: smp_rep_zone_perm_tbl - invoke REPORT ZONE PERMISSION TABLE function

NAME

       smp_rep_zone_perm_tbl - invoke REPORT ZONE PERMISSION TABLE function

SYNOPSIS

       smp_rep_zone_perm_tbl   [--append]   [--bits=COL]   [--help]  [--hex]  [--interface=PARAMS]  [--multiple]
       [--nocomma]  [--num=MD]  [--permf=FN]  [--raw]  [--report=RT]  [--sa=SAS_ADDR]  [--start=SS]  [--verbose]
       [--version] SMP_DEVICE[,N]

DESCRIPTION

       Sends  one or more SAS Serial Management Protocol (SMP) REPORT ZONE PERMISSION TABLE function requests 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.

       This  SMP function returns zone permission descriptors which represent rows of the zone permission table.
       There is a row for each source zone group starting at zone group 0 and finishing at  zone  group  127  or
       zone group 255.  Due to the SMP response size restriction of 1028 bytes (including trailing CRC), not all
       the zone permission table rows can be returned in one REPORT ZONE PERMISSION TABLE function response.  So
       multiple  function  calls  may  be  required with the --start=SS option being used on the latter calls to
       specify the next starting source zone group.

       The --multiple option will send multiple REPORT ZONE PERMISSION TABLE  requests  until  all  source  zone
       groups  (or  starting  from  --start=SS) are output. This option is the most convenient way to output the
       whole zone permission table. In the absence of the --multiple option  only  one  REPORT  ZONE  PERMISSION
       TABLE request is sent.

       The  output  of  this utility is designed to be useful as input to the smp_conf_zone_perm_tbl utility. In
       other words these utilities can be used to save and restore zone permission table settings.

OPTIONS

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

-a, --append
used in conjunction with --permf=FN to append to FN if it already exists. If FN does not exist
then it is created.

-B, --bits=COL
This is an alternate zone permission table represention showing single bits with the origin (i.e.
ZP[0,0]) in the top left. The output is a bit array with COL columns and up to COL rows. This
output resembles the example zone permission tables shown in the SAS draft documents (at t10.org).
The default (i.e. without this option) is output that reflects the byte oriented, big endian
nature of SCSI (and hence SMP) commands. The output produced by this option is not suitable as
input for the smp_conf_zone_perm_tbl utility.

-f, --start=SS
starting (first and lowest numbered) source zone group (default: zone group 0).

-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.

-m, --multiple
starting at source zone group 0 (or SS), multiple REPORT ZONE PERMISSION TABLE requests are issued
until the last (127th and 255th) source zone descriptor is output. This option should not be given
together with the --num=MD option.

-N, --nocomma
output each zone group descriptor as a long string of hexadecimal digits, two digits per byte.
Default action is to output a comma separated list of hexadecimal ASCII bytes for each zone group
descriptor.

-n, --num=MD
where MD is the maximum number of descriptors that can be reported in the one response. The
default value is 63. 63 is the maximum number of "128 zone groups" sized descriptors that can fit
in one response. If the expander is using "256 zone groups" sized descriptors then a maximum of 31
descriptors can fit in one response. This option should not be given together with the --multiple
option.

-P, --permf=FN
FN is a file to write the zone permission descriptors to. The default action is to output the zone
permissions descriptors to stdout. Note that the whole permissions table may not fit in one
response. If the FN exists then it is truncated prior to the write unless --append is given. To
append to the existing FN add the --append option.

-r, --raw
send the response (less the CRC field) to stdout in binary. All error messages are sent to stderr.

-R, --report=RT
set the 'report type' field in the SMP request. RT may take these values: 0 for report current
values (default); 1 for report the shadow values; 2 for report saved values; 3 for report default
values.

-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.

-f, --start=SS
See entry above, listed in order by its short option letter (i.e. -f).

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

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

NOTES

       When  the --permf=FN is given and SS is greater than zero then a line of the form "--start=SS" is written
       to FN just prior to the first row of zone permissions.

       There are some examples of the --permf=FN format in the examples directory.

CONFORMING TO
