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] SMP_DEVICE[,N]

DESCRIPTION¶

Sends a SAS Management Protocol (SMP) REPORT PHY ERROR LOG request function to a 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. 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.

-h, --help: output the usage message then exit.
-H, --hex: output the response 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 127. Default is 0.
-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.

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 .
