RTFI-ing NetApp HCI Nodes (1.6P1 Update)

Thought I’d do an update to my November 2018 post ‘Creating Bootable USB Sticks to RTFI* NetApp HCI Nodes’, since I had to create some new USB Sticks for HCI 1.6P1.

Download HCI 1.6P1 from:

solidfire-rtfi-sodium-patch3-11.3.1.5.iso
solidfire-compute-sodium-patch3-11.3.0.14235.iso

Creating the bootable USB sticks is very simple:

1) Use Rufus 3.3 for the Storage Node image

Default settings in Rufus 3.3 is fine (except I select cluster size = 8192 bytes, but don’t think it really makes a difference).

Note: On my PC with new USB keys it took 3 minutes.

2) Use Rufus 2.6 for the Compute Node image

Default settings in Rufus 2.6 is fine.
Important to use the DD image mode (not ISO mode as per the Storage Node image.)

Note: On my PC with new USB keys it took 20 minutes.
Note: We do the Storage Node images first using rufus 3.3, since it downloads the correct version of ISOLINUX for rufus 2.6 to use later (rufus 2.6 cannot download the correct version.)
