    I had a similar problem with the LSI controller. I've every single disk exported as a JBOD device.

  2. Are you trying to use a filesystem solution like ZFS, which prefers RAW disks? If so, the better long-term approach is to use a dedicated SAS controller (HBA) instead of a RAID controller. I tend to prefer LSI's offerings.
