# smp\_rep\_general(8)

invoke REPORT GENERAL SMP function

## NAME

smp\_rep\_general - invoke REPORT GENERAL SMP function

## SYNOPSIS

**smp\_rep\_general** \[*--brief*\] \[*--changecount*\] \[*--help*\] \[*--hex*\] \[*--interface=PARAMS*\] \[*--raw*\] \[*--sa=SAS\_ADDR*\] \[*--verbose*\] \[*--version*\] \[*--zero*\] *SMP\_DEVICE\[,N\]*

## DESCRIPTION

Sends a SAS Serial Management Protocol (SMP) REPORT GENERAL function request to an SMP target. 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.

## OPTIONS

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

- **-b**, **--brief**

  reports (prints to stdout) only a few important fields from the response.

- **-c**, **--changecount**

  reports (prints to stdout) the value of the expander change count field from the response. The value is printed in decimal and is in the range 0 to 65535. Only expanders compliant with SAS-1.1 (and earlier) should yield 0. \[Expanders compliant with SAS-2 (and later) should set the "long response" bit in the REPORT GENERAL response to 1.\]

- **-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.

- **-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.

- **-z**, **--zero**

  zero the Allocated Response Length field in the request. This is required for strict SAS-1.1 compliance. However this option should not be given in SAS-2 and later; if it is given an abridged response may result.

## EXAMPLES

See "Examples" section in http://sg.danny.cz/sg/smp\_utils.html

## CONFORMING TO

The SMP REPORT GENERAL function was introduced in SAS-1, with small additions in SAS-1.1 . There have been a large number of additions in SAS-2 .
