Help with mpt2sas kernel message

Kernel: vanilla 3.7.2.

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)

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.

The contents are:
lrwxrwxrwx 1 root root 0 Dec 10 19:49 0000:03:00.0 -> ../../../../devices/pci0000:00/0000:00:05.0/0000:03:00.0/
lrwxrwxrwx 1 root root 0 Dec 10 19:49 0000:04:00.0 -> ../../../../devices/pci0000:00/0000:00:07.0/0000:04:00.0/

lspci for those:
03:00.0 Serial Attached SCSI controller: LSI Logic / Symbios Logic SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] (rev 03)
04:00.0 Serial Attached SCSI controller: LSI Logic / Symbios Logic SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] (rev 02)

I am able to figure out which drives are on which of these controllers from
/sys/block

So far, I'm not seeing any data errors. 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.
