Hello Expert Toasters:

We have Filer F820 with 42 disks, OS is Netapp release 6.1R1. It was running good for last two years ( my finger cross here.) Now suddenly I got the error below from the logs.

MCA: fatal Processor error. in process raid_xor_server on release NetApp Release 6.1R1

Netapp fix this with replacing System board and its RAM.

My question to you all: What is "raid_xor_server mean in this error" means?

I am more concern on disks array then Systems Board or RAM.

Anyone has this problems before any would like to share. I would appreciated.

Thanks,

C-
