I just setup a new box with a single, dual-port SAS controller, a JBOD chassis with two expanders, and all dual-port SAS drives, but I'm not seeing any multipath devices showing up in the UI. Instead, what I'm seeing is a semi-random scattering of daxx devices with numbers ranging between 1 and 90 (there are 45 drives). I'm assuming that the ones that are missing are the second ports on each drive. When the machine boots I see all 90 of the devices fly by so they're all detected but the multipath devices don't seem to be initialized correctly.

From a hardware perspective, this is all wired correctly and should be working. Thoughts?

Ok, I flashed the LSI SAS adapters from FW 7 to 12 and now multipath is working... Mostly. One out of 45 disks didn't end up in a multipath device.
