Using the IO Accelerator as swap with ESX
HP does not recommend using the IO Accelerator as swap space when using the ESX host.
However, the IO Accelerator can be used as swap for virtual machines. To use the IO Accelerator as
swap for a virtual machine:
1. Go to VMware vSphere Client > Configuration > Virtual Machine Swapfile Location.
2. Indicate the appropriate Datastore location as the virtual machine swapfile location.
Disabling the driver using ESX
By default, the driver automatically loads when the operating system starts. VMware ESX does not allow a
driver to be unloaded, so you must disable driver auto-load for diagnostic or troubleshooting purposes.
To disable driver auto-load, run these commands:
$ esxcfg-module -d iomemory-vsl
$ esxcfg-boot -b
This prevents the IO Accelerator driver from loading so the device will not be available to users. However,
all other services and applications are still available.
Enabling the driver using ESX
To enable the IO Accelerator driver after maintenance run the following commands, and then restart the
system:
$ esxcfg-module -e iomemory-vsl
$ esxcfg-boot -b
Uninstalling the driver utilities using ESX
To uninstall the driver utilities, run the following command:
$ rpm –e fio-util
