Ubuntu Manpage: smp_rep_phy_err_log - 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 .
