Upgrading devices for IO Accelerator VSL 2.3.10
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 > 2.2.0 > 2.3.10
For example, if your device is using the firmware for IO Accelerator VSL version 1.2.7, upgrade to 2.2.0
(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.
IMPORTANT: When running multiple firmware upgrades in sequence (such as going from 1.2.7
to 2.2.0 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.
Do not downgrade device firmware
New IO Accelerator devices are shipped with recent firmware versions, often the minimum version required
for the device.
CAUTION: Do not downgrade the IO Accelerator device to an earlier version of the firmware.
Earlier versions of the firmware might not be compatible with the device, and downgrading the
firmware might result in data loss. If you must downgrade your firmware, contact HP Customer
Support (http://www.hp.com/support) for compatibility information and to discuss your use
case.
If you are installing new IO Accelerator devices in a system using older devices and firmware, upgrade the
older devices to the latest firmware and driver as a best practice.
