3par V-class arrays, code 37 reset and data corruption

Last week one of the nodes in our 3par v800 reset with a Code 37, and a few seconds before the node reset Oracle started to complain about corrupt blocks. In digging into this issue, it seems that there is a known hardware problem on the V-Class arrays. The issue stems from the PCI-E interface chipset on the system board and fibre channel cards.

We were told that we were the only customer to see data corruption with a Code 37 reset, but your mileage may vary. If you've had similar problems, I'd love to hear about it.

The following output from showeeprom shows a bad and good board:

I'm told that boards with revision D2 contain the fixes for the issue:
