Steve,

Step 1 is separate and should be done first. Step 3 happens automatically upon rebooting under 6.3.1R1 (or any other OnTap version). The annoyance is doing a hard down, a system 'halt' for the firmware so that you are at the ? prompt. The system then reboots to your current version, then you do the OnTap upgrade. Depending on the number of disks, this could take up to 20 minutes for a fully loaded (we have 12 disk shelves with 36 gb drives) F840.

Hope this helps.

I'm going to upgrade to 6.3.1 R1. This is my first upgrade so I have a few questions.

As I see it there are three steps.

1. Upgrade System Firmware 2. Upgrade ONTAP 3. Upgrade Disk Firmware

Is that the order I should do it in and should I do it all at the same time or spread them out say one per week?
