HP B- Accelerators Linux manual Loading the IO Accelerator driver, Fio-attach /dev/fct

fio-attach /dev/fct*

10.Using the following command, check the status of all devices: fio-status-a

Your IO Accelerator devices are now successfully upgraded for this version of the HP IO Accelerator. You can now install any IO Accelerator Gen2 devices.

Loading the IO Accelerator driver

1.Load the driver:

$ modprobe iomemory-vsl

The driver automatically loads at system boot. The IO Accelerator is now available to the operating system as /dev/fiox, where x is a letter.

For this command to work on SLES 10 systems, you must edit the /etc/init.d/iomemory-vslfile init info and change udev to boot.udev. The file should look like the following:

### BEGIN INIT INFO

#Provides: iomemory-vsl

#Required-Start: boot.udev

On SLES systems you must allow unsupported modules for this command to work:

oSLES 11 Update 2: Modify the /etc/modprobe.d/iomemory-vsl.conffile, and then uncomment the appropriate line:

#To allow the ioMemory VSL driver to load on SLES11, uncomment below

allow_unsupported_modules 1

oSLES 10 SP4: Modify the /etc/sysconfig/hardware/config file so the LOAD_UNSUPPORTED_MODULES_AUTOMATICALLY sysconfig variable is set to yes:

LOAD_UNSUPPORTED_MODULES_AUTOMATICALLY=yes

2.Confirm that the IO Accelerator device is attached: fio-status

The output lists each drive and status (attached or unattached).

NOTE: If the IO Accelerator device does not automatically attach, then check the /etc/modprobe.d files to see if the auto_attach option is turned off (set to 0).

Controlling IO Accelerator driver loading

Control driver loading through the init script or through the udev command.

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, though udev can be disabled and the init script used in nearly all cases. For older Linux distributions without this functionality, users must rely on a boot-time init script to load needed drivers. HP Support can provide an init script in /etc/init.d/iomemory-vslto load the VSL driver in older RHEL4 releases and SLES10 distributions.

Using the init script

On systems where udev loading of the driver does not work or is disabled, the init script might be enabled to load the driver at boot. On some distributions, it might be enabled by default.
