C – Troubleshooting

Useful Programs and Files for Debugging

Q

--workdir=DIR

Use DIR to hold intermediate files created while running tests. DIR must not already exist.

-k, --keep

Keep intermediate files that were created while performing tests and compiling reports. Results will be saved in a directory created by mktemp and named infinipath_XXXXXX or in the directory name given to --workdir.

--skip=LIST

Skip the tests in LIST (e.g. --skip=2,4,5,7 will skip tests 2, 4, 5, and 7)

-d, --debug

Turn on -xand -vflags in bash.

In most cases of failure, the script suggests recommended actions. Please see the ipath_checkout man page for further information and updates.

C.9.9

ipath_control

This is a shell script that can be used to manipulate various parameters for the InfiniPath driver. Many of them are intended to be used only when diagnosing problems, and may require special system configurations. Use of the options may require restarting the driver or utility programs in order to recover from incorrect parameters.

Most of the functionality is accessed via the /sys filesystem. This shell script gathers the same information contained in these files:

/sys/bus/pci/drivers/ib_ipath/00/boardversion /sys/bus/pci/drivers/ib_ipath/00/status_str /sys/bus/pci/drivers/ib_ipath/version

These files are also documented in table C-2and table C-3.

Other than the -ioption, this script will need to be run with root permissions. The -ioption is listed here, as it is the most commonly used. See the man pages for

for more details. Here is sample usage and output:

$ ipath_control -i
