Have you checked your SAS cabling? Also, lsiutil is for lsi1068 (3G) SAS chips. I've got a SuperMicro SC847 attached to a pair of lsi sas2008-based boards. The chassis is internally arranged as a pair of backplanes, each with two LSI SAS2x36, chained to appear as a single connector from the back of the chassis (i.e. one connector per SAS channel bundle for two fully redundant paths to the drives). Initially I was having trouble with excessive link errors which resulted in poor performance, lots of errors and generally lots of problems, but I found this was caused by a faulty SAS cable between the host and the chassis. Ever since playing around with cabling a bit it's been ticking reliably like a Swiss clock.
