Driver Installation Fails And System Cannot Be Booted; Cannot Remove Linux Driver With Uninstaller Application Or; Scripts; Removing Ethernet (Network) Drivers Causes Error - Dell Brocade Adapters Troubleshooting Manual

Driver installation fails and system cannot be booted

Installation of a new Windows 2008 driver package fails in systems where an adapter is used for
booting over SAN and the operating system becomes unbootable.
Possible Cause: Existing driver package that was accessing the remote boot LUN was removed and
system was rebooted.
Action: Install the new adapter driver without uninstalling the existing driver. This is the
recommended procedure for updating adapter drivers.
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.
Cannot remove Linux driver with uninstaller application or scripts
When removing the Linux driver package using the Brocade Software Uninstaller application or
script command (brocade_install_rhel.sh -u), the network (bna) or storage (bfa) driver will not
uninstall, and a message such as the following will display:
Uninstalling the Brocade driver <version> RPM's
Unloading bna driver ...
ERROR: Module BNA could not be unloaded; Uninstall terminated!
Possible Cause: An application such as HCM may be running and accessing the bna or bfa driver
module. Execute the rmmod bna or rmmod bfa command and verify that the following displays:
ERROR: Module bna is in use
or
ERROR: Module bfa is in use
Action: Run the fuser -v /dev/bfa and fuser -v user/dev/bna commands to list the PIDs and names
of processes accessing the bfa or bna modules. Kill the processes accessing these modules and
then retry driver removal.
