Install options

The cluster wizard prompts for general information on how to setup the cluster.

In the Target hosts section:
  • The ESS I/O servers must not be a part of the Ambari cluster.
  • Ambari requires a list of fully qualified domain names (FQDNs) of the nodes in the cluster.
  • Verify that the list of the host names used in the Ambari Target Hosts section are the data network addresses that IBM Spectrum® Scale uses for the cluster setup. Otherwise, during the installation of the IBM Spectrum Scale service, the installation fails and gives an Incorrect hostname error.
  • Ensure that the hostname does not have mixed case. Otherwise, failures might occur when starting services. It is recommended to use all lower case.

For this deployment, the ssh user is set to root.

If you plan to use a non-root user id, see Restricting root access.
