Ubuntu Manpage: smp_rep_exp_route_tbl - invoke REPORT EXPANDER ROUTE TABLE LIST SMP function

NAME

       smp_rep_exp_route_tbl - invoke REPORT EXPANDER ROUTE TABLE LIST SMP function

SYNOPSIS

       smp_rep_exp_route_tbl [--brief] [--help] [--hex] [--index=IN] [--interface=PARAMS] [--num=NUM] [--phy=ID]
       [--raw] [--sa=SAS_ADDR] [--verbose] [--version] SMP_DEVICE[,N]

DESCRIPTION

       Sends  a SAS Serial Management Protocol (SMP) REPORT EXPANDER ROUTE TABLE LIST function request to an SMP
       target and decodes or outputs the response. The SMP target  is  identified  by  the  SMP_DEVICE  and  the
       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.

       There  are  two expander route table types: phy-based and expander-based.  The expander-based route table
       was introduced in SAS-2 and supersedes the phy-based route tables. The REPORT EXPANDER ROUTE  TABLE  LIST
       function  is  associated with an expander-based route table. There is no corresponding CONFIGURE function
       because a expander-based route table is self-configured.

OPTIONS

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

-b, --brief
reduce the decoded response output.

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

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

-i, --index=IN
IN is the starting routed SAS address index. The default value is 0.

-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, --num=NUM
maximum number of descriptors to fetch (default is 62). Note that maximum SMP frame size is 1028
bytes (including a trailing 4 byte CRC) so 62 descriptors is the maximum number that can fit in
one response.

-p, --phy=ID
starting phy identifier within bitmap. ID should be one of 0 (the default), or a multiple of 48.
Note there is only one expnder route table per expander, not one per phy.

-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. Typically this is an expander. This option may
not be needed if the SMP_DEVICE has the target's SAS address within it. 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.

CONFORMING TO

       The SMP REPORT EXPANDER ROUTE TABLE LIST function was introduced in SAS-2 .
