Installing LSF-HPC With SLURM Into an Existing Standard LSF Cluster

2. If additional software (such as rsh) was not installed, use the following procedure to update the
golden image and propagate these changes with minimal impact to a running cluster. (This
action propagates changes only to those nodes that are up and running):
a. Update the golden image with the following command:
# updateimage --gc `nodename nh` --image base_image --no-netboot
b. Use the pdcp command to propagate the specific file changes to all nodes:
# pdcp -a /etc/sysconfig/iptables.proto /etc/sysconfig/iptables.proto
# pdcp -a /etc/profile.d/lsf.sh /etc/profile.d/lsf.sh
# pdcp -a /etc/profile.d/lsf.csh /etc/profile.d/lsf.csh
# pdcp -a /etc/init.d/lsf /etc/init.d/lsf
c. Refresh the firewall on all nodes with the following command. This will update the
/etc/sysconfig/iptables file on all nodes with the changes made in a
previous step:
# pdsh -a /opt/hptc/etc/nconfig.d/C04iptables nconfigure
