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 5-5describes 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.
