We recently inherited several Proliant HP-SL270s Gen 8 with P420 raid controller. Loading 16.04 with kernel 4.4.0-31 I cannot see the logical disk, I disabled Intel Vt-d (same as IOMMU) and this did not fix. There was a similar bug that expired where disabling IOMMU allowed the disks to be seen on a ProLiant BL465c Gen8

Ubuntu 14.04 can see the logical disk on the installer, would really like to load 16.04. FYI Red Hat 7 can see the disks also.
