Upgrade notes
Firmware version
This version of the IO Accelerator driver is compatible with firmware archive version 107004.
When this archive file is used, newer IO Accelerator devices, such as the IO Accelerator Gen2 device, are
updated to firmware version 107004. Previous devices, such as the IO Accelerator Gen1 device, are
updated to firmware version 107006 or 107007 (HP IO Accelerator for BladeSystem c-Class).
Upgrading devices for IO Accelerator VSL 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 must upgrade all of the existing devices to the latest firmware version.
Upgrade path
IMPORTANT: When running multiple firmware upgrades in sequence (such as going from 1.2.7
to 2.1.0 to 2.3.1), after each subsequent firmware upgrade you must reboot the system, load the
IO Accelerator driver (if it does not automatically load with your operating system), and attach
each device.
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 > 2.2.3 > 3.1.x
For example, if your device is using the firmware for IO Accelerator VSL version 1.2.7, upgrade to 2.2.3
(both IO Accelerator VSL and compatible firmware) and then continue on the path. 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) for each version. General upgrade instructions,
including the firmware update instructions, are available in the HP IO Accelerator User Guide for each
operating system.
