With the 5x00 adapters you need to reboot and handhold the BIOS. The sample I have has bad firmware, and doesn't do this right, but they've just posted a firmware upgrade that is meant to resolve this, as well as adding support for RAID10 (mirrored stripes - go-faster stuff). The 6x00 adapters are meant to resolve all this; I'll have one next week and will be adding support ASAP. Note that you can't do *any* of this with ccd or Vinum (apart from the online rebuild), and you can't get a reliable boot volume without a BIOS-level solution. I'd love to see Vinum understand the Promise config information, for example. -- ... every activity meets with opposition, everyone who acts has his rivals and unfortunately opponents also.
