We have currently a FAS2220 Ontap 8.1 working perfectly. We plan to upgrade from a single controller to a HA Pair. We kept 3 HDD in order to assign it to the new controller.
I was wondering if there is any procedure ?
Thank you very much.

If you still have 3 free disks it's no problem (It's probably best to use RAID 4 + Spare in that case, and remember that the "current" controller still needs at least one spare!)
However, you need a downtime/reboot for this procedure
just do this:

Thank you very much for your reply.
I'm just concerne about the point 5.
I found this documentation "Adding a second controller module to create an HA pair" (https://library.netapp.com/ecm/ecm_download_file/ECMM1280363)
I'm just worried about the point when the system ask to initialize all disks. As the first head is already in production I don't want to lose my data.
Do you have any Advice ?

It will initialize 3 disks from assigned to it. It will never automatically assign any disk during installation. So removing disk ownership is not enough - you have to also assign those disks to new controller.

I'm not sure that that is true when you initialize disks using the boot menu. I searched also in the documents, but can't find step where you need to assign disk ownership to the new controller.

We are in the same situation here. We have a fas2220 and planning to upgrade to a HA pair. including adding a extra diskshelf
I was wondering how the initialize all disk went...
