IMPORTANT: All commands require administrator privileges. To run the commands, log in as root or use sudo.

IMPORTANT: If you came to this section from the Software Installation section, return to that section after you uninstall previous versions of the driver and utilities.

Unloading the IO Accelerator driver

Unload the IO Accelerator driver:

$ modprobe –r iomemory_vsl

Uninstalling the IO Accelerator driver RPM package

Versions 1.2.x

Remove prior versions of the IO Accelerator software:

$ rpm -e iodrive-driver

Versions 2.x.x

With version 2.x.x of the IO Accelerator, you must specify the kernel version of the package that you are uninstalling.

Find the installed driver packages:

$ rpm -qa grep -i iomemory

Sample output:

iomemory-vsl-2.6.18-194.el5-2.2.2.82-1.0

For example, to uninstall the IO Accelerator (specifying the kernel version of the driver you wish to uninstall):

$ rpm -e iomemory-vsl-2.6.18-194.el5-2.2.0.82-1.0

Uninstalling the IO Accelerator Utilities, IO Accelerator Management Tool 2.x, and other support packages

Uninstall the support RPM packages (adding or removing package names as needed):

$ rpm -e fio-util fio-snmp-agentx fio-common fio-firmware iomanager-gui iomanager-jre libfio libfio-doc libfusionjni fio-sysvinit fio-smis fio-snmp-mib libfio-dev

To uninstall the support DEB packages, (adding or removing package names as needed):

$ dpkg -r fio-util fio-snmp-agentx fio-common fio-firmware iomanager-gui iomanager-jre libfio libfio-doc libfusionjni fio-sysvinit fio-smis fio-snmp-mib libfio-dev

Disabling auto attach

When the IO Accelerator driver is installed, it is configured to automatically attach any devices when the driver is loaded. When necessary, disable the auto_attach feature.
