More googling, and then something I wouldn't have thought of: smartctl doesn't work on this HBA against /dev/sd*. HOWEVER, it's happy as a clam against /dev/sgx, and there's my RAID, /dev/sg0 and /dev/sg1 (which lshw also was able to show me), but now, at least, I can run smartctl tests on the drives, and hopefully one will say, "Bad! Bad!". mark _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx https://lists.centos.org/mailman/listinfo/centos
