HP IO Accelerator Driver 3.1.1 Release Notes

Upgrade notes 11
Overformatting not supported
The –o overformat option is not supported in the 3.x.x VSL software. All upgraded HP IO Accelerator
devices are formatted to the maximum advertised capacity, regardless of whether the device was
overformatted prior to the upgrade.
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.
