NetApp FAS Zero disk procedure

We recently had a need to zero out and reinstall a NetApp FAS 8080 in order to move it from test to production.  Below are the steps to zero out the disks in the array.

Steps:

1. SSH to each nodes service-processor
2. Halt each node.
   1. system node halt -node Node1 -inhibit-takeover true
   2. system node halt -node Node2
3. At the Loader prompt for each node boot ONTAP (You might want to do these one at a time so you don’t miss the CTRL-C for the Boot Menu)
   1. LOADER A> boot_ontap
   2. LOADERB> boot_ontap
4. Press Ctrl + C when you see the message below to enter the Boot Menu and select option 4 to wipe the configuration and zero disks (Do this on each node)

*******************************

(1) Normal Boot.
(2) Boot without /etc/rc.
(3) Change password.
(4) Clean configuration and initialize all disks.
(5) Maintenance mode boot.
(6) Update flash from backup config.
(7) Install new software first.
(8) Reboot node. Selection (1-8)? 4

5. Enter y to the questions that follow:

Zero disks, reset config and install a new file system?: y

This will erase all the data on the disks, are you sure?: y

The node will reboot and start initializing the disks.  Once the disks are zeroed the system should reboot to the cluster setup.
