As a follow-up, I tried a SuperMicro enclosure (SC847E26-RJBOD1). I have 3
sets of 15 drives. I got the same results when I loaded the second set of
drives (15 to 30).
Then, I tried changing the LSI 9200's BIOS setting for max INT 13 drives from
24 (the default) to 15. From then on, the SuperMicro enclosure worked fine,
even with all 45 drives, and no kernel hangs.
I suspect that the BIOS setting would have worked with >1 MD1000 enclosure, but
I never tested the MD1000s, after I had the SuperMicro enclosure running.
I'm not sure if the kernal hang with max int13=24 was a hardware problem, or a
Solaris bug.
