Ubuntu Manpage: smp_rep_self_conf_stat - invoke REPORT SELF-CONFIGURATION STATUS SMP function

NAME

       smp_rep_self_conf_stat - invoke REPORT SELF-CONFIGURATION STATUS SMP function

SYNOPSIS

       smp_rep_self_conf_stat   [--brief]  [--help]  [--hex]  [--index=SDI]  [--interface=PARAMS]
       [--last] [--one] [--raw] [--sa=SAS_ADDR] [--verbose] [--version] SMP_DEVICE[,N]

DESCRIPTION

       Sends a SAS Serial Management Protocol (SMP)  REPORT  SELF-CONFIGURATION  STATUS  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.

-b, --brief
lessen the amount of header information output and compress each self confuration
status descriptor to one line of output.

-h, --help
output the usage message then exit.

-H, --hex
output the response (less the CRC field) in hexadecimal.

-i, --index=SDI
SDI is the starting self-configuration status descriptor index, an integer in the
range 0 to 65535. The default value is 1 . If SDI is 0 then no descriptors are
placed in the response plus the "starting self-configuration status descriptor
index" and "total number of self-configuration status descriptors" fields in the
response are both set to 0. That makes setting SDI to 0 a lot less useful tha it
could have been. SDI may be decimal (default) or hexadecimal prefixed by '0x' (or
'0X') or with a 'h' (or 'H') suffix.

-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.

-l, --last
Sends a REPORT SELF-CONFIGURATION STATUS request to find out the contents of the
"last self-configuration status descriptor index" field in the response. If it is
different from SDI then it re-issues that request with the "starting self-
configuration status descriptor index" field set to the "last" value. Often only
the last (i.e. most recent) recorded descriptor is of interest and that is what
this option should show. In cases there may be more than one descriptor starting at
the last index.

-o, --one
If multiple self-configuration status descriptors are found, then only output the
first one.

-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.

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

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

NOTES

       The "last self-configuration status descriptor index" field in the response  may  indicate
       the  lowest  index  of  the last recorded (i.e. most recent) "clump" of status descriptors
       placed in the expander's storage.

       This utility flags the "last self-configuration status descriptor index" descriptor in its
       output  with  a  ">>>"  indication. For brief output the descriptor line starts with ">>>"
       while for normal output (i.e. when --brief not given) the index has ">>>" placed in  front
       of it.

CONFORMING TO

       The SMP REPORT SELF-CONFIGURATION STATUS function was introduced in SAS-2 .
