A Network Profile is a collection of network settings that are used to provision database server VMs in NDB. A Network Profile can include one or more VLANs, IP ranges, and DNS servers. To make new VLANs available when provisioning an Oracle cluster database, you need to update the Network Profile to include the new VLANs. You can do this by editing the existing Network Profile or creating a new one with the new VLANs. You do not need to create or update the VLANs in Prism Element, as NDB can discover the VLANs configured in AHV1. References:
