SCSA HBA Entry Point Summary

SCSA defines a number of HBA driver entry points. These entry points are listed in the following table. The entry points are called by the system when a target driver instance connected to the HBA driver is configured. The entry points are also called when the target driver makes a SCSA request. See Entry Points for SCSA HBA Drivers for more information.
