Windows Server environments 19
• Installs and loads the IO Accelerator Windows® driver. (When complete, you will need to reboot the
system.)
• Installs support for SNMP (if installed, and if Microsoft® SNMP is installed and the SNMP service is
running).
When the installation program creates the IO Accelerator folder on the drive, it also creates these sub-folders:
• \Driver—Installs manually using Device Manager.
• Firmware—Contains the latest IO Accelerator firmware.
• SMI-S—Currently not used; reserved for future SMI-S use.
• SNMP—Contains the SNMP components.
• Utils—Contains the IO Accelerator command line utilities.
To continue installation, go to "Upgrading the device firmware using Windows (on page 23 )."
Upgrading device firmware from VSL 1.x.x or 2.x.x to
3.x.x
CAUTION: You cannot downgrade an HP IO Accelerator device firmware to an earlier version
after you have upgraded the device.
CAUTION: Upgrading IO Accelerator devices that were previously configured for VSL 1.x.x or
2.x.x to work with VSL 3.x.x requires a low-level media format of the device. No user data is
maintained during the media format process. Be sure to backup all data on your IO Accelerator
device as instructed before upgrading the firmware.
Version 3.1.x of the HP IO Accelerator VSL supports new features, including the latest generation of IO
Accelerator architecture and improved Flashback protection. These features require the latest version of the
firmware. Every IO Accelerator device in a system running 3.1.x or later must be upgraded to the latest
version of the firmware.
For example, if you have a system running 2.3.1 HP IO Accelerator VSL with IO Accelerator devices
previously installed, and you want to install new IO Accelerator Gen2 devices (that require the latest version
of the firmware), then you will need to upgrade all of the existing devices to the latest firmware version.
Upgrade path
Depending on the current version of your HP IO Accelerator device, to preserve the internal structure of the
device, you might have to perform multiple upgrades. The following path is the minimum upgrade path that
you must follow. Upgrade the HP IO Accelerator VSL software on the system, and upgrade the firmware to
the compatible version in the following order:
1.2.4 > 1.2.7 > 2.1.0 > 2.2.3 > 3.1.x
For VSL upgrade information for the HP IO Accelerator, see the HP IO Accelerator Release Notes on the HP
website ( http://www8.hp.com/us/en/support-drivers.html ). General upgrade instructions, including the
firmware update instructions, are available in the HP IO Accelerator User Guide for each operating system.
