Removing Software Packages
Instructions for uninstalling or downgrading InfiniPath and OpenFabrics software is
given below.
To uninstall the InfiniPath software packages on any node, using a
bash
shell, type
the command (as root):
# rpm -e $(rpm -qa ’InfiniPath-MPI/mpi*’ ’InfiniPath/infinipath*’)
This will uninstall the InfiniPath and MPI software RPMs on that node.
To uninstall the OpenFabrics software packages on any node, using a
bash
shell,
type the command (as root):
# rpm -e rpm_name_pre
rpm_name_pre
is the descriptive name that precedes the version and repository
identifiers in an RPM. For example:
# rpm -e libibverbs
This would uninstall
libibverbs-2.0- xxx .1_0_4.
yyy
.x86_64.rpm
on that
node.
For both InfiniPath and OpenFabrics it is recommended that you remove all the
packages at the same time.
3.20.1
Downgrading
If you want to downgrade, please remove both the InfiniPath and OpenFabrics
RPMs, then install the older bits. We have found that rpm flags like
"
--oldpackage
" will not generate a correct downgrade.

Installing Newer Drivers from Other Distributions
The driver source now resides in
infinipath-kernel
. This means that newer
drivers can be installed as they become available. Those who wish to install newer
drivers, for example, from OFED (Open Fabrics Enterprise Distribution), should be
able to do so. However, some extra steps need to be taken in order to install properly.
1. Install all InfiniPath RPMs, including
infinipath-kernel
. The RPM
infinipath-kernel
installs into:
/lib/modules/$(uname -r)/updates
This should not affect any other installed InfiniPath or OpenFabrics drivers.
2. Reload the InfiniPath and OpenFabrics modules to verify that the installation
works by using this command (as root):
# /etc/init.d/infinipath restart
