Rebuilding or Reinstalling Drivers After a Kernel Upgrade

An equivalent way to restart infinipath this is to use same sequence as above,

except use the restart command instead of start and stop:

# /etc/init.d/opensmd stop

# ifdown eth2

# /etc/init.d/infinipath restart

# ifup eth2

# /etc/init.d/opensmd start

You can check to see if opensmd is running by using the following command; if

there is no output, opensmd is not configured to run:

# /sbin/chkconfig --list opensmd | grep -w on

You can check to see if ipath_ether is running by using the following command.

If it prints no output, it is not running.

$ /sbin/lsmod | grep ipath_ether

If there is output, look at the output from this command to determine if it is

configured:

$ /sbin/ifconfig -a

When you need to determine which InfiniPath and OpenFabrics modules are

running, use the following command:

$ lsmod | egrep ’ipath_|ib_|rdma_|findex’

Rebuilding or Reinstalling Drivers After a Kernel

Upgrade

If you upgrade the kernel, then you must reboot and then rebuild or reinstall the

InfiniPath kernel modules (drivers).

To rebuild the drivers, do the following (as root):

# cd /usr/src/infinipath/drivers

# ./make-install.sh

# /etc/init.d/infinipath restart

To reinstall the InfiniPath kernel modules, do the following (as root):

# rpm -U --replacepkgs infinipath-kernel-*

# /etc/init.d/infinipath restart

NOTE:

Stopping or restarting InfiniPath terminates any QLogic MPI processes, as

well as any OpenFabrics processes that are running at the time. Processes

using networking over

ipath_ether will return errors.
