Determining the cluster configuration

There are different update procedures depending on whether the management host is installed locally and whether there is a shared configuration between hosts. Determine the configuration of your cluster to determine the specific update procedure to use.

About this task

The following steps determine whether your cluster is using a shared directory, installed locally with one management host, or installed locally with a shared configuration directory.

Procedure

  1. Log in to the LSF management host.
    Tip: Run the lsid command to see the name of the LSF management host to confirm that you are logged in to the proper host.
  2. Use the rpm -qi command to determine if the lsf-master RPM package is installed locally on the management host. 
    rpm -qi lsf-master
    • If the rpm -qi command shows that the lsf-master package is not installed, LSF is running from a shared file system. For more information, see Updating IBM Spectrum LSF Suite for Workgroups on a shared file system.
    • If the rpm -qi command shows that the lsf-master package is installed, LSF is installed locally on the management host. Determine whether your cluster is using a single-host POC installation.
  3. If LSF is installed locally on the management host, check the configuration on the deployment host to determine if the cluster is using a shared configuration.
    1. Log in to the deployment host.
    2. View the /opt/ibm/lsf_installer/playbook/lsf-config.yml file.
    3. Note the values of the HA_shared_dir and NFS_install_dir parameters to determine if the cluster is using a shared configuration.

What to do next

After determining your cluster configuration, update your cluster using the applicable procedure.
