Converting AFF (A300) to FAS8200

Hello, I am trying to convert an AFF (A300) HA pair of controllers into a FAS8200. We got these nodes really cheap as an add-on to a much larger purchase and want to use it in your lab with SSD, SATA and SAS drives. I tried going into Loader and doing 'set-defaults', but noticed the 'bootarg.init.flash_optimized false' was still set so I tried running the command below and got an access denied message... 


LOADER-A> setenv bootarg.init.flash_optimized false
Cannot set variable
*** command status = Access denied(-69)


Please help, how can I perform this conversion? Thanks!


Re: Converting AFF (A300) to FAS8200

As far as I know, personality change was allowed only for old FAS/AFF 80X0 systems.

And not possible with newer FAS/AFF generations.

Re: Converting AFF (A300) to FAS8200

I actually think it was never possible to convert any AFF into a "regular" FAS system - they are factory locked to support SSD drives only.

From a commercial point of view, a FAS system (e.g. 8200) with SSD shelves costs more than its AFF equivalent (A300 in this case) with the same SSD shelves.

Re: Converting AFF (A300) to FAS8200

It was possible in BIOS <=9.3 and ONTAP <=8.3.2 to change it, using the LOADER, which then writes the setting to the boot media, but it is now a WORM variable - it can be set, but not unset. 


It's not impossible to change it, but not inside the box of what we provide as "ONTAP" - it's not supported or publically documented. If it's a mis-ship or a mis-quote, please contact your account team and support for procedure to fix. And if they need help - they're welcome to contact me.

Hey @AlexDawson. Thanks for the clarification.

Where have you found that information?

Re: Converting AFF (A300) to FAS8200

There is an internal KB article on the restriction, and I've had to go through through our process with one of my customers in the past.

Re: Converting AFF (A300) to FAS8200

So I was basically right when I said you could do it ONLY with 80X0 because as @AlexDawson mentioned, it is possible only with ONTAP 8.3.2 and lower (BIOS 9.3 and lower) to change the flash optimized option in the LOADER.

And only AFF80X0 systems support  ONTAP 8.3 (See HWU) because AFF was introduced with ONTAP 8.3 for AFF80X0.


And the smallest versions for A300/FAS8200 are BIOS 11 and ONTAP 9.1 (See HWU). Therefore, you cannot change the flash optimized option in those models if you bought the system not in pieces but rather as a storage system. 


But you can change the flash optimized option with ANY ONTAP/BIOS version for any AFF in the LOADER, in case if you bought your controller as a separate FRU (for example if you purchased X3172A separately; it is the main board for A300/FAS8200), and as Alex mentioned, you can do it only ONCE.

Re: Converting AFF (A300) to FAS8200

Thanks all for your input...


When we purchased these nodes, they did not have a purpose. I think NetApp at the time was really trying to push the AFF line (A300, etc) so they were almost giving them away (as they did for us). We had a really large purchase at the time, and with how fast we are growing our NetApp infrastructure, figured we could use them somewhere. Well, that somewhere is our lab so we can have supported gear there finally. As of now, we only have an old unsupported FAS6220. Since we want a hybrid system with both spinning disk and flash, we were hoping to just be able to remove the all flash personalities and make it a FAS8200 system since it's the same hardware. So, to answer your question @AlexDawson, no this wasn't a mis-ship/mis-config, it is a repurpose after the fact... So, what steps would I need to do to convert it (if it's even possible)? This system will only ever be a FAS8200, never going back to A300. Back-revving it to 8.3x is not an option since it's unsupported per HWU. Also, if doing this renders the A300's unsupported then that kind of defeats the purpose as well, so it would have to be a supported operation. 


Our sales team has said this is unsupported, but are waiting confirmation. 

Re: Converting AFF (A300) to FAS8200

@craig_schuer Since you already have the access denied message, most probably your controllers already were part of a system.

In this case, there is nothing you or NetApp can do.

Re: Converting AFF (A300) to FAS8200

Hi Craig,


I've reached out to Eddie Hu (I believe your account rep?) with details.


I think if you're after it for a supported system you plan to run long term, it probably isn't something supportable. The cases I've seen (and there's only been a handful) have needed to convert to enable a migration or something similar, and are then set back to AFF.


The AFF personality enables additional efficiencies both on disk and in terms of processing, as well as our parts management systems may eventually complain about shipping spinning disks to an AFF contract. There's the additional issue of AFF sales being something we report to the market (but maybe by capacity only, not number of controllers..) and to market analytics companies, so changing the number of AFF systems sold might create upstream headaches.
