## Configuration Management 

The Configuration Management module handles requests of the create, delete, or change types, which are needed to manipulate KSYS objects ( IBM.VMR  resources). Such requests come either directly from the ksysmgr  commands that are entered by the user, or indirectly from other modules that are running their specific jobs. All initial elementary steps, such as when you first define the KSYS cluster, add HMCs and hosts, and then create a host group, are typical configuration steps. Any reverse elementary steps, such as when you delete host groups, hosts, and HMCs, are also typical configuration actions. 

## Discovery and verification 

After host group creation, you must run a discovery operation for the host group, as shown in Example 2-55. 

ksysmgr discover host_group <hg_name> [verify=<yes|no>] 

During this initial discovery of a host group, the KSYS subsystem deploys a special monitoring setup for the involved VMs and hosts. It creates an SSP cluster that is based on the input that is specified in the preliminary configuration steps. The real SSP cluster (Example 2-7 on page 50) of a host group is represented in the KSYS configuration by an associated IBM.VMR_SSP  resource (Example 2-56).
