If the /lib/modules/OS_version/updates directory is not present, then the
driver in use is the one that comes with the core kernel. In this case, either the
kernel-ib RPM is not installed or it is not configured for the current running
kernel.
If the updates directory is present, but empty except for the subdirectory
kernel, then an OFED install is probably being used, and the ident string will
be empty. For example:
$ cd /lib/modules/OS_version/updates
$ ls
kernel
$ cd kernel/drivers/infiniband/hw/qib/
lib/modules/2.6.18-8.el5/updates/kernel/drivers/infiniband/hw
/qib
$ ident ib_qib.ko
ib_qib.ko:
ident warning: no id keywords in ib_qib.ko
ipath_checkout
The ipath_checkout tool is a bash script that verifies that the installation is
correct and that all the nodes of the network are functioning and mutually
connected by the InfiniPath fabric. It is installed from the infinipath RPM. It
must be run on a front end node, and requires specification of a nodefile. For
example:
$ ipath_checkout [options] nodefile
The nodefile lists the hostnames of the nodes of the cluster, one hostname per
line. The format of nodefile is as follows:
hostname1
hostname2
...
NOTE
For QLogic RPMs on a RHEL distribution, the drivers folder is in the
updates folder instead of the kernels folder as follows:
/lib/modules/OS_version/updates/drivers/
infiniband/hw/qib/ib_qib.ko
NOTE
ident is in the optional rcs RPM, and is not always installed.
