smp_conf_general

NAME

smp_conf_general - invoke CONFIGURE GENERAL SMP function

SYNOPSIS

smp_conf_general [--connect=CO] [--expected=EX] [--help] [--hex] [--inactivity=IN] [--interface=PARAMS] [--nexus=NE] [--raw] [--sa=SAS_ADDR] [--verbose] [--version] SMP_DEVICE[,N]

DESCRIPTION

Sends a SAS Management Protocol (SMP) CONFIGURE GENERAL request function to a 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. With one interface there is one SMP_DEVICE per machine so the SMP_DEVICE,N syntax is needed to differentiate between HBAs if there are multiple present.

OPTIONS

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

-c, --connect=CO

sets the "update STP maximum connect time limit" flag and the corresponding "STP maximum connect time limit" field to CO. Unit of CO is 100 microseconds. A CO of zero is taken to mean no maximum connection time limit.

-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 in hexadecimal.

-i, --inactivity=IN

sets the "update STP bus inactivity time limit" flag and the corresponding "STP bus inactivity time limit" field to IN. Unit of IN is 100 microseconds. A IN of zero is taken to mean no bus inactivity time limit.

-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, --nexus=NE

sets the "update STP SMP I_T nexus loss time" flag and the corresponding "STP SMP I_T nexus loss time" field to NE. Unit of NE is one millisecond. A NE of zero is taken to mean a vendor specific amount of time; a NE of 65535 means the port shall never recognize an I_T nexus loss.

-r, --raw

send the response 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 CONFIGURE GENERAL function was introduced in SAS-2 .
