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. > > I'd also like to know which card mpt2sas0 is.

The disks on this controller is 8x 3tb in raid6 with 128k chunk. Thanks for your response. -- Microsoft has beaten Volkswagen's world record. Volkswagen only created 22 million bugs.
