Discovery of an X3-2 Exadata Database Machine target in EM Cloud Control 126.96.36.199.1 fails to find Compute Nodes and errors with:
"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 agent is installed using a custom (additional) hostname for management network, in this case this interface is used for RMAN backups.
Example: axdb0101c-mi.acme.com << This is where the agent was installed
Hostname: axdb0101c.acme.com << This is what the "hostname" command returns on the compute node itself
IB switches ibnetdiscover show: axdb0101c-adm.acme.com << This is the ADMIN hostname
Installed the agent on a dedicated hostname that is used for Management traffic (RMAN and DataGuard)
