Thanks Joshua, read here: http://h20564.www2.hpe.com/hpsc/doc/public/display?docId=mmr_kc-0100329 "FIX:HPE will not have a HP Dynamic Smart Array driver developed for the Oracle Solaris Operating Systems. Meaning Oracle Solaris Operating System will not support the OEM'd LSI controllers in RAID mode, but they will be supported with RAID mode disabled (HBA mode). When users disable RAID mode for HP Dynamic SmartArray B320i/B120i the controller name will be H220i (DLs) or H210i (blades)." Looks like I can disable raid mode on the Dynamic Smart Array and let it work as an LSI controller? What about the P420? Do you think I can have jbod mode on it?

It features 2 hba controllers: 1- HP Dynamic Smart Array B120i RAID controller (with 4 disks, I will use 2 as a mirrored boot) 2- Smart Array P420 (some TB of disks) I want to completely bypass hardware array raid and use jbod or similar. I found documents around saying that I can just configure each disk as a single array in the controller, obtaining the same effect. I don't think this is a good idea. While it is technically possible to create a non-redundant logical volume on each physical disk, this is _not_ the same as having a proper JBOD/target-mode HBA. In particular, the RAID controller will not expose proper fault or hot-plug information back to the operating system. If you have a disk failure or other problem, it's not clear that you'll be able to pull out the failed disk and plug a new one in and have it work, at least without rebooting and possibly reconfiguring the RAID controller. I'm also not sure that we have a driver for the "Dynamic Smart Array", which I believe is a different series of parts to the regular "Smart Array" controllers like the P420. My strong recommendation is to install a real JBOD-mode HBA -- something like an LSI IT-mode card supported by "mpt_sas" would probably be best. If you're not going to do that, I would probably let the RAID controller manage redundancy on the disks, e.g. using by creating a single RAID-6 logical volume, and create a single-vdev ZFS pool (i.e. no redundancy at the ZFS layer).
