Hi,
NetApp actually has a great document on this topic but I have a few questions and want to see if the community has any input or if anyone has actually done this before.
The document (https://now.netapp.com/NOW/knowledge/docs/hardware/filer/215-03653_A0.pdf) in summary explains:
1. Making sure you have 3 unowned disks for ONTAP
2. Setting up the existing controller as a netboot server
3. Physically installing and connecting the new controller
4. Assign an IP, netboot, and install ONTAP on the new controller
5. Install the OS on the new controller and add licenses
6. Run setup on the existing controller to add partner IP
7. Reboot bother controllers and enable failover
8. Clone the config to the new controller
This all makes sense except:
1. The document says the system auto-assigns 2 disks to the new controller. I have 4 spare disks on one shelf which I plan on removing ownership of 3 (one spare) of them for ONTAP. Does it matter what shelf ONTAP is installed on? Will the system auto-assign the unowned disks?
2. Will all my existing aggrs, vols, and data be ok?
3. What about reassigning disks now that there is a second controller?
Thanks in advance,
Ryan
