Can you point me to a list of codes?  Is this message something that I
should be concerned about?  I haven't seen this message before, however, I
changed all the disks in the array and replaced the controller (The mptsas
wouldn't support 3tb disks).  The chassis is external and the card has 2
external minisas connectors.  About the only thing that didn't change was
the chassis and the computer.

That would be the 2 minisas controller then.  The disks on this controller
is 8x 3tb in raid6 with 128k chunk.

Thanks for your response.
