The following list provides prerequisites required for agentless configuration:

• You must install the Control Host Add-on on one or more managed hosts and/or the Management Server.

  Veritas Operations Manager lets you discover a host through the Control Host. The Control Host helps you manage discovery data from agentless hosts and can discover HBAs, andles on the host, multipathing, Linux LVM, and file systems (including ZFS). Agentless discovery does not support the discovery of databases and applications.

• A UNIX Control Host cannot be used to agentlessly discover Windows hosts. If you plan to agentlessly discover Windows hosts, you will need to plan your Control Host deployment accordingly.

• You must install the Veritas Operations Manager Storage Insight Add-on for Deep Array Discovery and Mapping and configure arrays for deep discovery.

  The Veritas Operations Manager Storage Insight Add-on for Deep Array Discovery and Mapping must be deployed to enable correlation of OSHandles on the agentless hosts to array LUNs.

  If you make any configuration changes, for example creating new LUNs and making them visible to the host, on storage arrays, then the agentless discovery that occurs after a subsequent SI deep array discovery will reflect the changes on the agentless hosts. After making changes to the array, one SI deep discovery needs to occur and only then a subsequent agentless discovery will pick up the changes on the host.
