So, you already have Management Network VMkernel Port. Now, for the portgroup OS-Internal and OS-Data, which in documentation is referred as ONTAP-Internal and ONTAP-External, the steps you need to follow for a standard vSwitch are:
- Assign separate NICs for these portgroups or share the same set of NICs that the management network is on.
- Set the MTU speeds on them to 9000
- Set the load-balancing policy as per the best practice guide for standard vSwitch
- You need IPs for cluster management, individual ONTAP node IPs. I believe that you might put them in separate VLAN.
- Therefore, these port groups need to be VLAN tagged with the VLAN number. The ONTAP-External is on a routable VLAN. The ONTAP-Internal to be on a non-routable VLAN; but, even if you put the same VLAN as external or leave it blank, it should work.
I'm not sure whether you are creating a single-node or multi-node cluster. For a single-node you don't need an ONTAP-Internal portgroup; just the external.
Also, what type of license are you using? Standard or premium and disk-types - hybrid or SSD. Note; OTS reserves the CPU/memory that is required based on the license type. So ensure you have enough capacity from a compute perspective, since I see that you have other VMs too on the same server.
If you doing it through the GUI, the steps are simple as you navigate post these port group creation.
