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