NetApp ONTAP 9.1: OnCommand System Manager On-Box Guided Cluster Setup

I was never a fan of ‘System Setup’ (the GUI way of setting up pre-9.1 clusters), so when I heard that ONTAP 9.1 has an On-Box Cluster Setup, I wanted to try it out, so here we go!

Note i: With the VSIM you can’t use Guided Setup to create anything other than a single node cluster, if you try for a 2 node cluster it will complain that “HA is not configured”, but it would let you part do the first node in the cluster, and then you’d need to add the second VSIM node using CLI. With real world systems you won’t encounter this.

Note ii: Another problem I found with using Guided Cluster Setup against a VSIM, is that it gets stuck at ‘Step 2: Network’. The error is fairly vague, I’m pretty sure it’s due to the absence of service-processor on the VSIM. Again, with real world systems you won’t encounter this. The moral of the story “don’t use Guided Cluster Setup to setup a VSIM.”

Here we have 1 x ONTAP 9.1 simulator. The basic setup is similar to here - Build Recipe for 8.3.2 - up to and including step 1.8 (node setup).

Guided Cluster Setup

1) Point your web browser at https://NODE_MGMT_IP

And the below is what you should see. A very cool feature is that you can download/upload a template (in CSV format - see the Appendix for more).

2) Click the ‘Guided Setup’ button.

2.1) Cluster

- Input Cluster name
- Input Node name
- Tick the single node cluster box
- Input admin password
- Click Submit

Note: The Cluster Base License is now optional in 9.1’s setup (mandatory to add Feature Licenses).

2.2) Network

- Input network details as required (see image below)
- Click Submit

... and this is where we get stuck with the VSIM. Still, hopefully this post wasn’t a total fail and you can see the potential (check out the Appendix for the CSV details!)

Image: Error in the input fields. Verify the field values before proceeding.

Appendix: Cluster Setup Template

The Cluster Setup Template functionality will be very useful. The CSV/XLSX can be downloaded from ‘Guided Cluster Setup’. I’m not going to copy and paste the CSV template here, just detail the fields to give an idea of what it could be used for (up to 8 node cluster setup!)
