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] [--ver‐
sion] SMP_DEVICE[,N]
DESCRIPTION
Sends one or more SAS Serial Management Protocol (SMP) REPORT ZONE PER‐
MISSION 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 mul‐
tiple 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 mul‐
tiple 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 pro‐
duced 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 hexadeci‐
mal 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 hexa‐
decimal 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 direc‐
tory.
CONFORMING TO
