We're running DOT 7-mode (v8.0.2) and just experienced a failover on our filer2. I've run the following commands from the sp on that filer and attached the output:
I did notice in the system logs this error preceded the failover:
PANIC: nested machine check exception detected on CPU 2, no coredump will be generated.
If someone could provide me with some insight into this error and how serious it is I would appreciate it, we would like to giveback but are unsure if that is wise.
Solved! SEE THE SOLUTION

I ran the err message through the Data ONTAP Panic Message Analyzer on mysupport.netapp.com.
Response: 'The panic message could not be safely matched to a single bug.'
8.0.2 Is an older release - you might want to consider doing an upgrade soon.
Given no signs of hardware failure, you're probably OK to do the giveback...
I hope this response has been helpful to you.

What the others said, please do an uprade sooner rather than later. 8.0.2 is rather old and since it's an unpatched release contains a few annoying bugs... your NetApp partner should be able to tell you more about it and help you upgrade your system.
The hardware in question isn't, by chance, a FAS3140? We had similar problems with a few 3140's once which were only fixed by upgrading everything to a more recent version (OnTap, BIOS, disk/shelf firmware, etc.)

Thanks for the feedback, we did a giveback a few days ago, so far so good.
We're in the process of migrating to a new cDOT 8.3P1 cluster.
