the service in the default OFF orientation, because few nodes run this service. Use the following
procedure:
1. Log in as the superuser on the head node.
2. Use the squeue command to ensure that no current LSF-HPC with SLURM jobs are running
and that the SLURM queues are idle.
3. Install the software on the golden client.
Note the names of the services that are created as a result.
4. Create global or node-specific configuration files (gconfig or nconfig) or both, if the
services will run only on some specialized nodes.
5. Place the gconfig files in /opt/hptc/etc/gconfig.d, the nconfig files in
/opt/hptc/etc/nconfig.d, and the configuration files in /opt/hptc/etc/cconfig.d,
using an appropriate priority ordering based on the prefix of the file name.
6. Update the /opt/hptc/systemimager/etc/chkconfig.map file by adding the new
service names, with the service orientation OFF for all run levels. The nconfig, the
configuration script, or both, enable the service only on those nodes on which they are
intended to run.
7. Execute all gconfig scripts and update the golden image:
# /opt/hptc/config/sbin/cluster_config
8. Determine the name of the node that provides the imageserver service with the shownode
command:
# shownode servers imageserver
The node name returned is used as the argument to the --server option in the next step.
9. Distribute the golden image update to all nodes by using the information in “Propagating
the Golden Image to All Nodes” (page 149).
