I am not sure if this is a kernel issue, an MD issue, or something else. It is happening across several different HBAs (LSI and Intel) on the same unit. We could try updating to 3.6.8. Is there a known issue with RAID shutdown or device shutdown in that kernel that does this? The 3.2.x series didn't do this. Nor did the 3.5.x series. Thanks! Joe
