# smp\_rep\_exp\_route\_tbl(8)

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.
