 This support may be enabled by setting the desired role of the core via
 the LSI Logic firmware utility that establishes what roles the card
 can take on - no separate compilation is required.
+.Sh WARNINGS
+Most controllers supported by the 
+.Nm
+driver suffer from limitations on supported disk size (mostly <2TB).
+While *most* controllers will truncate usable disk size, others might
+behave unexpetedly and can cause severe data loss.
+Refer to the datasheet of your chipset and firmware version for information
+about supported disk size and limitations.
