I–Useful Programs and Files
Summary and Descriptions of Useful Programs
Here is sample usage and output:
% ipath_control -i
$Id: QLogic OFED Release 1.5 $ $Date: 2010-03-01-23:28 $
0: Version: ChipABI 2.0, InfiniPath_QLE7342, InfiniPath1 6.1, SW
Compat 2
0: Serial: RIB0941C00005 LocalBus: PCIe,5000MHz,x8
0,1: Status: 0xe1 Initted Present IB_link_up IB_configured
0,1: LID=0x1 GUID=0011:7500:0079:e574
0,1: HRTBT:Auto LINK:40 Gb/sec (4X QDR)
0,2: Status: 0x21 Initted Present [IB link not Active]
0,2: LID=0xffff GUID=0011:7500:0079:e575
The -i option combined with the -v option is very useful for looking at the
InfiniBand width/rate and PCIe lanes/rate. For example:
% ipath_control -iv
$Id: QLogic OFED Release 1.5 $ $Date: 2010-03-01-23:28 $
0: Version: ChipABI 2.0, InfiniPath_QLE7342, InfiniPath1 6.1, SW
Compat 2
0: Serial: RIB0941C00005 LocalBus: PCIe,5000MHz,x8
0,1: Status: 0xe1 Initted Present IB_link_up IB_configured
0,1: LID=0x1 GUID=0011:7500:0079:e574
0,1: HRTBT:Auto LINK:40 Gb/sec (4X QDR)
0,2: Status: 0x21 Initted Present [IB link not Active]
0,2: LID=0xffff GUID=0011:7500:0079:e575
0,2: HRTBT:Auto LINK:10 Gb/sec (4X)
NOTE:
On the first line, Release version refers to the current software release.
The second line contains chip architecture version information.
ipath_mtrr
Another useful option blinks the LED on the InfiniPath adapter (QLE7240 and
QLE7280 adapters). This is useful for finding an adapter within a cluster. Run the
following as a root user:
# ipath_control -b [On|Off]
NOTE:
Use ipath_mtrr if you are not using the default PAT mechanism to enable
write combining.
