F–Useful Programs and Files

Summary and Descriptions of Useful Programs

IB6054601-00 H F-9

Most of the functionality is accessed via the /sys filesystem. This shell script

gathers the same information contained in these files:

/sys/class/infiniband/ipath0/device/boardversion

/sys/class/infiniband/ipath0/device/status_str

/sys/class/infiniband/ipath0/device/driver/version

These files are also documented in Tabl e F- 4 and Table F-5.

Other than the -i option, this script must be run with root permissions. See the

man pages for ipath_control for more details.

Here is sample usage and output:

% ipath_control -i

$Id: QLogic OFED Release 1.4 $ $Date: Mon Feb 23 21:39:17 PST 2009

0: Version: ChipABI 2.0, InfiniPath_QLE7280, InfiniPath1 5.2, PCI

2, SW Compat 2

0: Status: 0xe1 Initted Present IB_link_up IB_configured

0: LID=0x8 MLID=0xc042 GUID=00:11:75:00:00:ff:8f:37 Serial:

AIB0807A28872

The -i option combined with the -v option is very useful for looking at the IB

width/rate and PCIe lanes/rate. For example:

% ipath_control -iv

$Id: QLogic OFED Release 1.4 $ $Date: Mon Feb 23 21:39:17 PST 2009

0: Version: ChipABI 2.0, InfiniPath_QLE7280, InfiniPath1 5.2, PCI

2, SW Compat 2

0: Status: 0xe1 Initted Present IB_link_up IB_configured

0: LID=0x8 MLID=0xc042 GUID=00:11:75:00:00:ff:8f:37 Serial:

AIB0807A28872

0: HRTBT:Auto RX_polarity_invert:Auto RX_lane_reversal: Auto

0: LinkWidth:4X of 1X|4X Speed:DDR of SDR|DDR

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:

On the first line, Release<version> refers to the current software release.

The second line contains chip architecture version information.
