NAME¶
smp_rep_phy_event_list - invoke REPORT PHY EVENT LIST SMP function
SYNOPSIS¶
smp_rep_phy_event_list [
--help] [
--hex]
[
--index=IN] [
--interface=PARAMS] [
--raw]
[
--sa=SAS_ADDR] [
--verbose] [
--version] [
--zero]
SMP_DEVICE[,N]
DESCRIPTION¶
Sends a SAS Management Protocol (SMP) REPORT PHY EVENT LIST function request 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. 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, --index=IN
- starting phy event list descriptor index. ID is a
value between 1 and 65535. Default is 1.
- -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.
- -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.
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 EVENT LIST function was introduced in SAS-2 .
