VMWare ESX environments 64
8. Find the files with those UIDs in /vmfs/devices/disks/. Select the files with appended partition
numbers. In this case:
/vmfs/devices/disks/mpx.vmhba2:C0:T0:L0:1
/vmfs/devices/disks/mpx.vmhba3:C0:T1:L0:1
9. Enter the following command to pass that file to vmkfstools and create a vmfs format:
vmkfstools -C vmfs3 -b 4M FILE -S LABEL
where FILE is the file from above and LABEL is a handy label such as fio1.
HP recommends that you produce VMDK files in the COS with vmkfstools rather than through the
GUI, since this gives you more options.
vmkfstools -c SIZE -d eagerzeroedthick /vmfs/volumes/LABEL/NAME.vmdk
where SIZE is the volume size (for example, 400G), LABEL is the label you supplied to
vmkfstools to create the VMFS format, and NAME is the name used to refer to this VMDK.
10. In vSphereCenter or vCenterServer, right-click the ESX system in the window on the left, and
then select Rescan for datastores.
Upgrading the firmware using ESX
Once the IO Accelerator driver is loaded, ensure that the firmware is updated. To do this, run the fio-
status command-line utility from a supported environment.
If the output shows that the device is running in minimal mode, download the latest firmware from the HP
website (
http://www.hp.com/go/support ), then use the fio-update-iodrive utility from a supported
environment to upgrade the firmware.
NOTE: If your driver version is earlier than 1.2.4, you must upgrade to Version 1.2.4 before
upgrading to Version 2.x.
Working with IO Accelerator devices and PCI pass-
through
Each IO Accelerator device can either be used as a VMFS datastore in ESX or passed through to a virtual
machine. In VMware documentation, this is often referred to as VMDirectPathIO.
NOTE: When passing through an IO Accelerator device to a virtual machine, use driver
Version 2.1.0 or later.
Using IO Accelerator Duos with PCI pass-through
IO Accelerator Duos have two memory modules per device. The driver does not support splitting the
modules between two functions or virtual machines. The following scenarios are supported:
• Both IO Accelerator modules are used as a VMFS datastore in ESX.
• Both IO Accelerator modules are passed through to the same virtual machine.
