History: Back in the day, we didn't have an initramfs to allow us to load disk drivers as modules. All disk drivers had to be built-in. In CentOS 7.3, the mpt2sas and mpt3sas driver code was reorganized to allow for a common code base. But along with that, those drivers would only now build as modules. We created a patch which involved taking a snapshot of mpt driver code, and massaged it all into building as built-in drivers. Problem: That old code snapshot along with the fact that those two drivers initialize without their associated hardware being present (they are built-in), seems to cause interference with some other LSI raid controllers, namely Harpoon in AVAGO MR9460-8i via a Huawei enclosure. Solution: Simply revert to building those two mptsas drivers as modules, the way CentOS intended. They will reside on initramfs and be loaded automatically if the appropriate hardware is present. With these drivers now out of the way, the problematic raid controller works fine, driven by the megaraid_sas driver.
