12. Follow along on the screen while the cluster_config utility configures the system.
NOTE: To avoid duplicating command output here, cluster_config output is shown
in Section 6.5 (page 105).
Continue to the next step in this procedure when the cluster_config processing is
complete.
13. Look at the backup copy of the slurm.conf file, which is located in the /hptc_cluster/
slurm/etc/slurm.conf.bak file. If you previously customized this file, you must merge
those customizations into the new version of the /hptc_cluster/slurm/etc/
slurm.conf file. Otherwise, omit this step.
14. Compare the final LSF configuration with the saved version to ensure that only the
appropriate changes relevant to the upgrade have occurred. Also ensure (or restore, if
required) the elim scripts.
HP recommends that you use another terminal window to install the elim scripts at the
point when the cluster_config utility displays the following prompt:
All user specified configuration is complete.
The Golden Image will be created next.
[P]roceed, [Q]uit:
Thus, changes to the /opt/hptc/lsf/top/7.0/ directory will be included in the golden
image. This is the directory where elim scripts reside.
Any changes to the LSF configuration files in the /hptc_cluster/lsf/conf/ directory
can occur after cluster_config has finished because this directory is not part of the
golden image.
If the LSF version has changed, binary paths (including the $LSF_SERVERDIR directory,
where elim scripts reside) have also changed.
15. Re-enter the monitoring line card entries in the /etc/dhcpd.conf file if the system is using
a Myrinet interconnect. See Section D.2 (page 200) for more information about adding entries
to this file.
If the system is using an InfiniBand, QsNet
II
, or Gigabit Ethernet interconnect, omit this
step.
16. Restart the power service:
