Alexis and I connected both a Adaptec 9410 and a LSI 1064E SAS initiator to an expander. Both machines saw the disks attached to the expander, and both could send I/Os to the disks. So far, so good. We then connected a SATA disk to the expander. libsas BUGd up in sas_ex_discover_end_dev (sas_expander.c:636): BUG_ON(sas_port_add(phy->port) != 0); mptsas didn't seem to do anything with the SATA device at all, though when we disconnected the SATA disk it recognized that a SATA device went away. We'll have a look at the libsas problem in a jiffy. --D
