2. Ensure that there are no filesystems or RAID volumes using the IO Accelerator, and then unload
the driver modules with this command:
modprobe -r fio-driver fio-port
This command may fail if you have not unmounted any filesystems or RAID volumes that are using
the IO Accelerator devices.
3. Run the following commands to uninstall the driver in this order:
rpm -e iodrive-snmp
rpm -e iodrive-jni
rpm -e iodrive-firmware
rpm -e iodrive-util
rpm -e iodrive-driver
4. Remove the IO Accelerator files left in the /usr/src/redhat/RPMS/x86_64/ directory on
RHEL, or the /usr/src/packages/RPMS/x86_64 directory on SLES
To install the new driver, see
NOTE:
There are new instruction within each new release. Make sure you read the release notes and the
install instructions to ensure no loss of data.

Unmanaged Shutdown Issues

Unmanaged shutdowns due to power loss or other circumstances will force the IO Accelerator to
perform a consistency check during the reboot. This may take several minutes or more to complete
and is shown by a progress percentage during Windows startup.
Although data written to the IO Accelerator will not be lost due to unmanaged shutdowns, important
data structures may not have been properly committed to the drive. This consistency check repairs
these data structures.

Exploring IO Accelerator Linux Driver Loading

In newer Linux distributions, users can rely on the udev device manager to automatically find and
load drivers for their installed hardware at boot time. For older Linux distributions without this
functionality, users must rely on a boot time init script to load needed drivers. HP provides an init
script in /etc/init.d/iodrive to load the IO Accelerator driver in RHEL4 and SLES10 distributions.

Controlling driver loading

Using the init scripts

On systems that use scripts to load drivers, users can enable or disable an init script with the standard
init script utility: chkconfig. By default, the IO Accelerator init script loads the driver at boot time.
You can disable this loading of the IO Accelerator driver with the following command:
