Rebuilding or Reinstalling Drivers if a Different
Kernel is Installed
Installation of the InfiniPath driver RPM (infinipath-kernel-2.2-xxx-yyy)
builds kernel modules for the currently running kernel version. These InfiniPath
modules will work only with that kernel. If a different kernel is booted, then you
must reboot and then re-install or rebuild the InfiniPath driver RPM.
Here is an example. These commands must be done as root:
# export IPATH_DISTRO=2.6.18_EL5.1 KVER=2.6.18-53.1.14.el5
# cd /usr/src/infinipath/drivers
# ./make-install.sh
# /etc/init.d/infinipath restart
Reinstallation instructions for the InfiniPath kernel modules are provided in
“Rebuilding or Reinstalling Drivers After a Kernel Upgrade” on page 5-28.
Further Information on Configuring and Loading
Drivers
See the modprobe(8), modprobe.conf(5), and lsmod(8) man pages for more
information. Also see the file:
/usr/share/doc/initscripts-*/sysconfig.txt
LED Link and Data Indicators
The LEDs function as link and data indicators once the InfiniPath software has
been installed, the driver has been loaded, and the fabric is being actively
managed by a subnet manager.
Table 5-5 describes the LED states. The green LED indicates the physical link
signal; the amber LED indicates the link. The green LED will normally illuminate
first. The normal state is Green On, Amber On for adapters other than the
QLE7240 and QLE7280, which have an additional state, as shown in Table 5-5.

The switch is not powered up. The software is neither
installed nor started. Loss of signal.
Verify that the software is installed and configured with
ipath_control -i. If correct, check both cable con-
nectors.
