Which LSI SAS controller are you using?

Yes you are right.

Also if this is a 3Gb SAS system, there is many fixes in the LSI drivers from the LSI web site. Most of the fixes are related to handling SATA devices on the SAS bus. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
