Table C-2. Useful Programs and Files

		Use to verify
Program or file name	Function	homogeneity?

boardversion	File. Check the version of the installed	Yes
	InfiniPath software.
chkconfig	Check configuration state, enable/disable	No
	services, including drivers.
ibstatus	Checks status of InfiniBand devices when	No
	OpenFabrics is enabled.
ibv_devinfo	Lists info about InfiniBand devices in use.	No
	Use when OpenFabrics is enabled.
ident	Identifies RCS keyword strings in files. Can	Yes
	check for dates, release versions, and other
	identifying information.
ipath_checkout	A bash shell script that performs sanity	Yes
	testing on cluster using InfiniPath hardware
	and software. If the program is run without
	errors, the node is properly configured.
ipath_control	A shell script that can be used to manipulate	Yes
	various parameters for the InfiniPath driver.
	This script gathers the same information
	contained in boardversion, status_str,
	and version.
ipathbug-helper	A shell script that gathers status and	Yes
	history information for use in analyzing
	InfiniPath problems.
ipath_pkt_test	Tests the InfiniBand link and bandwidth	No
	between two InfiniPath HCAs, or, using an
	InfiniBand loopback connector, within a
	single InfiniPath HCA.
ipathstats	Displays both driver statistics, and hardware	No
	counters, including both performance and
	"error" (including status) counters
lsmod	Shows status of modules in the Linux kernel.	No
	Can use to check whether drivers are loaded.
