Q

C.9.5

ibstatus

This program displays basic information on the status of InfiniBand devices that are currently in use when the OpenFabrics modules are loaded.

C.9.6

ibv_devinfo

This program displays information about InfiniBand devices, including various kinds of identification and status data. Use this program when OpenFabrics is enabled.

C.9.7

ident

ident strings are available in ib_ipath.ko. Running ident (as root) will yield information similar to the following. For QLogic RPMs, it will look like:

#ident /lib/modules/$(uname -r)/updates/*ipath.ko /lib/modules/2.6.16.21-0.8-smp/updates/ib_ipath.ko:

$Id: QLogic Release2.0 $

$Date: 2006-09-15-04:16 $

$Id: QLogic Release2.0 $

$Date: 2006-09-15-04:16 $

For non-QLogic RPMs, it will look like:

#ident /lib/modules/$(uname -r)/updates/*ipath_ether.ko /lib/modules/2.6.16.21-0.8-smp/updates/infinipath.ko:

$Id: kernel.org InfiniPath Release 2.0 $

$Date: 2006-09-15-04:16 $ /lib/modules/2.6.16.21-0.8-smp/updates/ipath.ko:

$Id: kernel.org InfiniPath Release2.0 $

$Date: 2006-09-15-04:20 $

NOTE: $ident is in the optional rcs RPM, and is not always installed.
