VMWare ESXi emulates an mptsas HBA, but exposes all drives as direct-attached SAS drives. This it not how the driver originally envisioned things; SAS drives were supposed to be connected via an expander, and only SATA drives would be direct attached. As such any hotplug event for direct-attach SAS drives was silently ignored, and the guest failed to detect new drives from within a VMWare ESXi environment.
