How to Discover Red Hat Cluster Suite Topology

This section describes how to discover the topology managed by Red Hat Cluster Suite.

ClosedPrerequisites
  • Ensure that there is shell connectivity to cluster nodes.
  • Set up SSH protocol credentials.
ClosedRun the Discovery

Note Red Hat Cluster Suite Discovery can be performed in shallow or deep mode. To perform a shallow discovery, carry out steps 1-3 below. To perform a deep discovery, carry out all of the steps below.

To perform Red Hat Cluster Suite Discovery, execute the following jobs in the listed order:

  1. Range IPs by ICMP (discovers the target IPs)
  2. Host Connection by Shell (discovers the target host and shell connectivity to it)

  3. Host Applications by Shell (discovers Red Hat cluster software)

    Note If you want to perform only a shallow discovery, stop here and do not continue to the next step.

  4. Red Hat Cluster by Shell (discovers Red Hat cluster resources)
