The Solaris 7 DDI/DKI does not support detaching an HBA driver, although target driver children of an HBA can detach. For best results, the HBA driver should fail a detach request. It's better to fail the detach than to include code that cannot be tested.
Example 14-3 provides an example of the xx_detach() function.
