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

HP XC preparation
You must perform the following steps to prepare to install LSF-HPC for SLURM into an existing
standard LSF cluster. Read through all of these steps first to ensure that you understand what is to be
done. All steps are performed via a login to the HP XC head node, and most of the steps involve
propagating changes to the rest of the cluster.
Ensure that LSF on HP XC is shut down
Use the following procedure to shut down and remove LSF:
1. If LSF was installed locally on HP XC and is running, shut it down as follows:
[root@xc128 conf]# controllsf stop
2. Remove this LSF installation by using the following configuration command. In this step, the LSF
installation is removed from the current LSF_TOP, which is /opt/hptc/lsf/top:
[root@xc128 conf]# /opt/hptc/etc/gconfig.d/C55lsf gunconfigure
removing /opt/hptc/lsf/top/conf...
removing /opt/hptc/lsf/top/6.0...
removing /opt/hptc/lsf/top/work...
removing /opt/hptc/lsf/top/log...
removing /hptc_cluster/lsf/conf...
removing /hptc_cluster/lsf/work...
removing /var/lsf...
3. Log out and log back in to clear your environment of any old LSF environment settings.
In the following procedure, a new LSF_TOP is mounted from the non-XC system plain.
Mount the LSF tree to XC
This procedure describes how to NFS mount the LSF_TOP location, (/shared/lsf in this example),
from the non-XC system.
1. On the non-XC system, (plain in this example), export the directory specified by 'LSF_TOP' to
the XC cluster. A typical existing LSF cluster already has this location exported to the other
nodes; you need only add the XC cluster. Refer to the following documentation, if necessary:
a. For UNIX and Linux systems, see the exports(5) reference (man) page for
instructions on exporting directories.
b. See the HP XC System Software Administration Guide and the
/hptc_cluster/etc/fstab.proto file for information on mounting external
fileservers cluster-wide.
2. Create the mount point cluster-wide.
