8. Reload all modules by using this command (as root):

#/etc/init.d/infinipath start

An alternate mechanism can be used, if provided as part of your alternate installation.

9.Run an OpenFabrics test program, such as ibstatus, to verify that your InfiniPath card(s) work correctly.

Installing for Your Distribution

You may be using a kernel which is compatible with one of the supported distributions, but which may not be picked up during infinipath-kernelinstallation. It may also happen when using make-install.shto manually recompile the drivers.

In this case, you can set your distribution with the $IPATH_DISTRO override. Run this command before installation, or before running make-install.sh. We use the RHEL4 Update 4 distribution as an example in this command for bash or sh users:

$ export IPATH_DISTRO=rhel4_U4

The distribution arguments that are currently understood are listed below. They are found in the file build-guards.sh.

These are used for RHEL, CentOS(Rocks), and Scientific Linux.

rhel4_U2 rhel4_U3 rhel4_U4

These are used for SLES, SUSE, and Fedora:

sles10

suse9.3

fc4

make-install.shand build-guards.share both found in this directory:

/usr/src/infinipath/drivers
