# smp\_rep\_phy\_err\_log(8)

invoke REPORT PHY ERROR LOG SMP function

## NAME

smp\_rep\_phy\_err\_log - invoke REPORT PHY ERROR LOG SMP function

## SYNOPSIS

**smp\_rep\_phy\_err\_log** \[*--help*\] \[*--hex*\] \[*--interface=PARAMS*\] \[*--phy=ID*\] \[*--raw*\] \[*--sa=SAS\_ADDR*\] \[*--verbose*\] \[*--version*\] \[*--zero*\] *SMP\_DEVICE\[,N\]*

## DESCRIPTION

Sends a SAS Serial Management Protocol (SMP) REPORT PHY ERROR LOG 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.

- **-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.

- **-p**, **--phy**=*ID*

  phy identifier. *ID* is a value between 0 and 254. Default is 0.

- **-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 option also zeros the Request 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.

## NOTES

Similar information is maintained for SAS SSP target phys (e.g. on a SAS disk). It can be obtained from the Protocol Specific Port log page with the sg\_logs utility.

Similar information may be obtained for SAS initiator phys (e.g. on a SAS HBA). As an example in Linux 2.6.28 error information can be found in this directory /sys/class/sas\_phy/phy-4:0 (for the phy 0 in SCSI/SAS host 4).

Similar information may be obtained for SATA device phys (e.g. on a SATA disk). If there is a SAT layer between OS and the SATA device then the sg\_sat\_phy\_event utility can fetch the information.

## CONFORMING TO

The SMP REPORT PHY ERROR LOG function was introduced in SAS-1 . The "Expander change count" field was added in SAS-2 .
