Rebuilding or Reinstalling Drivers After a Kernel Upgrade

S

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

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.

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
