I've heard that an onboard SATA controller and a PCI card SATA controller will cause drives to show up differently - for example: da0, da1, for the motherboard controller and ada0, ada1, for the PCI card (or something like that). The problem with this as I understand it is that you cannot add devices from the different controllers to the same zvol - example: I couldn't make a RAIDZ from ada0, ada1, and da0.
I currently have an M1015 HBA and HP SAS Expander, but I've realized I don't need all those ports, and dealing with a full-height card is becoming a pain. That being said, my question is simply - if I get another M1015 HBA and have both on the same system, will the devices show as 'being on the same bus'? Meaning that they're all 'daX' - and I can add them across the two M1015 cards.
Reasoning is the zvols will be in 3 drive RAIDZ zvols, and it doesn't go into 8 (ports on the M1015) evenly.
Thanks
