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

To summarize the current state of the installation:

• The scripts profile.lsf.xc and cshrc.lsf.xc scripts do not exist yet. You will establish

them after installing LSF-HPC for XC later in this procedure.

• You have seen that the names of the setup files are appended with the xc string. After installing

LSF-HPC for XC, you must rename the setup files to maintain the existing setup files.

• In a later step, you will propagate the new custom files /etc/profile.d/lsf.sh and

/etc/profile.d/lsf.csh to every node in the XC cluster.

Set up the XC LSF startup script

The XC controllsf command can also double as the Red Hat /etc/init.d/ service script for

starting and stopping XC LSF during boot and shutdown of the cluster. When starting LSF, this

command establishes the LSF alias and starts the LSF daemons. The command can start LSF on one of

the resource_management nodes only. It is safe, and also necessary for failover, to configure

controllsf on every node in the cluster.

To configure the controllsf command as the service script, create the appropriate soft-link:

[root@xc128 root]# which controllsf

/opt/hptc/sbin/controllsf

[root@xc128 root]# ln -s /opt/hptc/sbin/controllsf /etc/init.d/lsf

This configuration must be present on every node in the XC cluster. At this point, you have completed

the changes to the head node.

Completing the preparation

To complete the preparation,. update the golden image with the changes that you made in the

preceding sections, and propagate the changes to the cluster nodes. See HP XC System Software

Administration Guide for the recommended procedures to update the golden image and propagate

the changes. Complete the preparation as follows:

1. Use the cluster_config command to update the golden image if you must change XC roles

to ensure that all resource_management nodes have direct access to the external network.

Enter n (no) when prompted to install LSF locally.
