Troubleshoot IBM Spectrum LSF Suite for Workgroups installation

Troubleshoot typical IBM Spectrum LSF Suite for Workgroups installation scenarios.

If the start Elastic Search task fails, it might be that the previous uninstallation task did not completely clean the environment. In that case, run the following commands. 
systemctl stop elasticsearch-for-lsf.service
systemctl disable elasticsearch-for-lsf.service
rm -rf /etc/systemd/system/elasticsearch-for-lsf.service
systemctl daemon-reload
systemctl reset-failed

If the Elastic Search startup fails, it could be that the host name has two IP addresses assigned to it. To counteract this, follow the steps provided:

If multiple IP addresses are mapped to the same host, each IP address should map to a unique host name.

  1. Modify /etc/hosts to ensure a different IP address maps to a different host name:
    IP Address Host Name Alias
    127.0.0.1 localhost  
    9.21.53.77 ib22b07.eng.platformlab.ibm.com ib22b07
    9.21.53.77 ib22b07.eng.platformlab.ibm.com ib22b07

    is changed to:

    IP Address Host Name Alias
    127.0.0.1 localhost  
    9.21.53.77 ib22b07.eng.platformlab.ibm.com ib22b07
    9.21.53.77 ib22b07_1.eng.platformlab.ibm.com ib22b07_1
  2. Restart network service: 
    service network restart
  3. Make sure only the required IP address is mapped to the host name ib22b07
    hostname -i
9.21.53.77
  4. Rerun the suite installation. The Elastic Search daemon should start up correctly.
