If you want to unload your hba driver, you should make sure your hba device has no child in the device tree via "prtconf -D"
And if there are some sd instance under your hba, you can try "rem_drv sd" to unload the sd driver firstly, and then unload your hba driver. But before you unload sd driver, please make sure your boot system is not a SCSI disk, that means it is not drived by sd driver.
