TIP: In the event of an installation error, HP recommends you uninstall the Cluster Test executables, correct the reported problem, then repeat the installation. To uninstall the Cluster Test Executable use:

For Red Hat, SLES, and CentOS: /opt/clustertest/setup/ct_setup.sh -u

A prerequisite RPM is not installed. Although the installation checks and reports on the most common RPM prerequisites, it is possible that one of more required RPMs is not installed. In this case the installation will abort with a dependency error message specific to the missing component. The component must be installed before the Cluster Test RPMs will install.

4.Log out and then log in again to the node to update the PATH variable and load the Cluster Test aliases.

5.Edit /opt/clustertest/logs/.ct_config and add:

INFINIBAND=generic

6.If you are going to use OpenMPI, run mpi-selectorto select it as the default MPI, then log out and log in again to pick up the changes.

# mpi-selector --list mvapich2-1.9openmpi-1.6.5openmpi_gcc-1.6.4

#

7.Perform the following procedures to be sure the ib_send_bw and Linpack tests run correctly.

ib_send_bw test

The ib_send_bw test might not run successfully, generate an empty

ib_send_bw.analysis file, and report errors in the ib_send_bw.err file such as

Conflicting CPU frequency values detected: 2000.000000 != 1200.000000.

To be sure the test runs successfully, change the content of the /sys/devices/system/ cpu/cpu*/cpufreq/scaling_governor files from userspace or ondemand to performance by copying and running the following scripts on all nodes. Use the pdcp and pdsh commands to copy to the same location and run the scripts on all cluster nodes.

#cat substitute_performance_in_Filescaling_governor.sh for CPUFREQ in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor; do [ -f $CPUFREQ ] continue; echo -n performance > $CPUFREQ; done

#

After you run the script, verify your changes are reflected on all nodes.

#cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor performance

performance performance performance performance performance

Linpack test

The node-wise Linpack test might generate the following STDERR messages:

Node0: sh: hponcfg: command not found

Node0: sh: hponcfg: command not found or
