I have 2 mpt2sas controllers. I'm running a md check on the 2 arrays that I have (one per card). I'm seeing this in my kernel log (last 4 lines): 2013-12-10 19:52:10 kame kernel:[1558186.193904] mpt2sas0: log_info(0x31080000): originator(PL), code(0x08), sub_code(0x0000) 2013-12-10 19:52:35 kame kernel:[1558211.606908] mpt2sas0: log_info(0x31080000): originator(PL), code(0x08), sub_code(0x0000) 2013-12-10 19:53:02 kame kernel:[1558237.954502] mpt2sas0: log_info(0x31080000): originator(PL), code(0x08), sub_code(0x0000) 2013-12-10 19:53:50 kame kernel:[1558286.227318] mpt2sas0: log_info(0x31080000): originator(PL), code(0x08), sub_code(0x0000) Can someone tell me if there is a problem here? I'd also like to know which card mpt2sas0 is. Is it the one that has the lower numbered pci bus? I was unable to figure that out from /sys/bus/pci/drivers/mpt2sas.

Although drives on 03:00.0 appear to be running slower than the ones on 04:00.0 according to /proc/mdstat. No drives are actually in use other than the check that is running. -- Microsoft has beaten Volkswagen's world record. Volkswagen only created 22 million bugs.
