HP XC System Software Administration Guide Version 3.2

1. Log in as superuser (root) on the head node of the HP XC system.
2. Make sure any current LSF application on the HP XC system is shut down and won't interfere.
If LSF-HPC with SLURM is currently installed and running on the HP XC system, shut it
down with the controllsf command:
# controllsf stop
3. Consider removing this installation to avoid confusion:
# /opt/hptc/etc/gconfig.d/C55lsf gunconfigure
removing /opt/hptc/lsf/top/conf...
removing /opt/hptc/lsf/top/6.2...
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...
In this step, you remove the LSF installation from the current LSF_TOP directory,
/opt/hptc/lsf/top.
4. Log out then log back in to clear the LSF environment settings.
5. Mount a new LSF_TOP tree from the non-HP XC system plain using NFS, to the HP XC
system.
In this sample case, the LSF_TOP location is /shared/lsf on the non-HP XC system.
On plain , the non-XC system, export the directory specified by LSF_TOP to the HP
XC system.
For UNIX or Linux systems, see exports(5) for instructions on exporting directories.
Typically, an existing Standard LSF cluster has this location exported to the other nodes,
so you just need to add the HP XC system.
On xc (the HP XC system):
1. Mount the external file servers on a systemwide basis
See “Mounting File Systems” (page 215) and the
/hptc_cluster/etc/fstab.proto file for information on mounting external
file servers systemwide.
2. Create the mount point systemwide.
For the sample case, create the /shared/lsf directory on all the nodes:
# pdsh -a "mkdir -p /shared/lsf"
3. Edit the /hptc_cluster/etc/fstab.proto, specifically change the appropriate
fstab entry in the ALL section of this file
4. Edit the /hptc_cluster/etc/fstab.proto with the appropriate entry.
5. Restart the cluster_fstab service systemwide.
# pdsh -a "service cluster_fstab restart"
6. Ensure that the HP XC resource management nodes have an external connection.
The HP XC resource management node, which is configured as the LSF node, must be able
to communicate with, and receive communication from, the existing LSF cluster on the
external network.
Some of the options include adding additional network hardware to current resource
management nodes and reassigning the resource management role. See the HP XC System
Software Installation Guide for more information on configuring and reconfiguring roles in
HP XC.
Use the shownodes command to ensure that each node configured as a resource management
node during the operation of the cluster_config utility also has access to the external
network:
