Uninstalling a previously-installed driver
CAUTION:
Upgrading an IO Accelerator from Version 1.2.x to Version 2.x is a one-way
process. New firmware is required that is not compatible with 1.2.x systems. Be sure all data
is backed up before continuing with the upgrade.
Before installing a new driver, uninstall the previous version.
1.
Go to the Start menu.
2.
Open the Control Panel.
3.
Select Add or Remove Programs.
4.
Select the package or program.
NOTE:
Uninstall IO Manager and HP StorageWorks IO Accelerator software.
5.
Select Remove.
6.
Reboot the server, and then log in as a user with Administrative privileges.
If previous (downrev) drivers (such as driver files fiodrive.sys) exist on the system (typically located
in C:\Windows\System32\drivers) after you have uninstalled the software, then upon reboot,
Windows recognizes those drivers for the IO Accelerator. This situation causes issues with the installation
of Version 2.2.
After the software is uninstalled and the system is rebooted, Windows operating systems display a New
Hardware Found message and normally do not find a driver for the new device.
If a driver is found, go to Control Panel > Device Manager and search for HP IO Accelerator. View the
driver details and check the revision of the driver. If the HP IO Accelerator appears in the Device
Manager and the driver revision is not 2.x or later, manually uninstall the driver for each IO Accelerator
in the system, and then reboot the system.
If no driver is available, the HP IO Accelerator appears in the Device Manager as a mass storage
controller. The system must be in this state before you install the 2.x software.
