Exadata Database Machine Discovery Fails: The selected compute node is not an existing host target (Doc ID 1439314.1)

Last updated on JANUARY 30, 2014

Applies to:

Enterprise Manager for Exadata - Version 12.1.0.1.0 and later
Information in this document applies to any platform.

Symptoms

Unable to add Exadata targets (Compute Nodes, Storage cells, IB switches, PDUs etc)  into Cloud Control 12c

While discovering an Exadata Database Machine target, Step 2 of 7 fails to advance to the next step and displays the following error message:


Error
The selected compute node is not an existing host target managed by Enterprise Manager.  Please add the compute node as managed target before you continue.



The screen displaying the Database Machine Discovery components will list the compute nodes using the public domain names, rather than the management domain names.

For example:

exa01.public.domain.com

instead of

exadb01.management.domain.net


Changes

Configured the Exadata Machine with different domains for Public and Management networks.
