We have a FAS8200 that came with ONTAP 9.3 (yes, it sat for a while before being configured). Ran the setup wizard but did not set it up as a 2 node cluster for failover and wanted to re-run as if it were new. We booted the top controller, selecting CTRL-C for the boot menu and then selected Option 4:
(4) Clean configuration and initialize all disks.
Once that finished, the system will try and boot but multiple HD errors scroll across the screen stating that this system cannot access the drives. We tried again, selection option 4a in an attempt to rebuild the system LUN but it states "must have at least 3 drives" and indicates 0 drives available.
*Important: before selecting option 4, the initial setup wizard ran fine and completed. We then ran the same wizard on the bottom controller which also ran successfully. But now only the bottom of the two controllers seem to work correctly.
What can we do to get this top controller back? The end intention is to use these as a 2 node pair (HA). We also plan on updating the software to ONTAP 9.7. But that does not seem possible with the first controller in this state?
