Convert DS4243 to FAS2240-4 single controller

[Kavin]

I used FAS2240-2 controller into the DS4243 shelf, but it show 

========================================

PANIC : The FASXXXX:code(1) is not a supported platform

version: 8.1.4P7: Fri Nov 21 02:12:14 PST 2014
conf : x86_64
cpuid = 0
Uptime: 1s

=========================================

somebody know how can it work?

You need to open case with NetApp support. It may be solved by SP firmware update, but it sounds like you may need replacement.

Thanks for your relpy,

DataONTAP is 8.1.4P7

SP is 2.2.1

BIOS is 8.2

It is compatible

I found the problem!!
Must used the DS4243 shelf after 2012-11,
P/N:430-00025
or 
P/N:430-00061

Can't used DS4243 shelf before 2012-11,

like P/N:430-00048

Is there any way to make this work with a 430-00048? What are the differences with the ones manufactured after 2012-11?

Or perhaps you are implying that FAS2240-4 are built off DS4246 and not DS4243?

But then it would accept 6Gbps drives, but hardware universe shows that it only handles 3Gbps drives.

If not, then it should be possible to modify the DS4243 to accept a 2240-4 controller.

Or could it be that the shelf id wasn't set to zero?

For the benefit of anyone who finds this topic - the difference between the two models is that the newer one has a re-designed midplane PCB which allows greater airflow to the devices in the IOM/PCM slot to handle the slightly increased cooling required for the embedded controllers vs SAS expanders.

There is no way to force it to run in the older enclosures - with access to the developer resources, I have tried. ONTAP checks the part number at boot and refuses to boot in the older one.

The older ones have "Copyright 2008" visible on the midplane when the left-most column of drives is removed, and they were used for both DS4243 and DS4246 shelves.

Yes, all very complex, but this is why we don't support converting a shelf to a controller, only the other way around.
