Some sata drives just don't handle the sas-sata emulation combined with sas expanders.
Not only that, but I've found that the Seagate ST3500413AS (500 GB SATA 6Gb/s) won't work on my Intel SASUC8I HBA (basically an LSI SAS3081E-R, which uses the mpt driver). It'll work just fine on an AHCI port, but apparently the HBA can't successfully autonegotiate the 3 Gb speed.
No jumper is available to force 3 Gb operation. If I place a jumper on the typical Seagate speed limiter location, I get 1.5 Gb operation (but that's actually undocumented for this specific drive family - the documentation claims jumpers are unnecessary). I haven't tried the 1.5 Gb mode with the HBA, though.
Would a 6 Gb SAS HBA work with 6 Gb SATA drives? _______________________________________________ OpenIndiana-discuss mailing list OpenIndiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss
