There's a serial port on the rear of each controller. default user is "root". password will be whatever will be what ever was set. you can also reset this via the boot menu.
You can "factory default" it by booting and running option 4 on both nodes (second ctrl c for the boot menu) . HOWEVER. all license keys, config and data will be lost and are non-transferable and NetApp cannot provide them, so make sure you have them before you do that.
1. What for do i need license keys, its hardware what was paid?! I'm more into QNAP Systems and known to "push back button".
All FAS type systems are enterprise grade. The licenses enable the various features and protocols on the system and not transferable. They allow various features and protocols to be allowed to function on the controllers.
2. Is there no configuring option over the LAN-Port with a default IP ?
Yes, if you know the IPs/username/password. Otherwise, serial via CLI.
3. My last question is, what if i cant get the serial key again. Can i use it still as raid5 storage in a network? Dont really need more than that. I just want to use it for home usage.
You technically can, depends what the system is licensed for. To add, you would just never be able to wipe it or upgrade/patch it. (FYI it's not RAID 5, it's RAID-DP)
Thanks for your input, it's really useful to me. I would have never figured out all that stuff.
So i guess you would suggest to try to get the license key before to go any further,or?
Can you tell me how its about the maximum storage size? I know many vendors say up to X TB Harddisk but they also run with bigger ones without any problems (my QNAP Enterprise is running with 8x10TB and should only run with 2tb (vendor specs).
Is NetApp more strictly with this ? 2TB HDD means 2TBB HDD or could it be possible it runs with bigger ones "without warranty"?
If you say 2TB is 2TB, the FAS is going to trash 😞
