Hello all, [disclaimer: what follows is probably a really stupid idea after all.] We would like to use a LSI SAS 1068E board with Sil3726 SATA port replicators. This obviously "fails" in that only 1 disk out of the 5 connected is actually visible. I found, if SATA drivers are to support a port multiplier, they inhert from sata_pmp_port_ops. Is an analog infrastructure available for the sas-based HBAs to support SATA port multipliers? (BTW is such a setup actually supported form a protocol point of view?) I'm not a regular kernel hacker, so I cannot really help you in getting quality sata mpm support (if possible after all) into the sas drivers. What I can definitely offer is my time and will to test the driver modifications you would send me.
