General HBA and CNA problems
NOTE
If you remove the adapter driver (which requires a system reboot because the adapter was
modified), and then reinstall the driver, installation will fail because the operating system cannot
update the driver while a system reboot is pending. However, if you reboot the system after removing
the driver, the operating system will not come up because the driver accessing the operating system
was removed.
