Utilities 31
CAUTION:
• During a firmware upgrade, it is critical to maintain steady power or risk failure of
the IO Accelerator device. Connecting a qualified UPS is recommended prior to
performing a firmware upgrade.
• It is critical to load the driver after each firmware upgrade step when scheduling
sequential, multiple firmware upgrades (example: 1.2.7 to 2.1.0 to 2.3.1). If the
driver is not loaded, the on-drive format will not be changed and there will be
data loss.
• Data loss may occur if the IO Accelerator device firmware is downgraded.
Contact HP Support (
http://www.hp.com/support ) for recommendations.
• The default to upgrade all IO Accelerator devices does not use the -d or -s
option. The firmware is located in the file.
Confirm that all devices need the firmware upgrade. The -p (Pretend) option, can
be run to view the possible results of the update.
• Ensure that all IO Accelerator devices are detached before updating the
firmware.
• Upgrade Path
There is a specific upgrade path to follow when upgrading an IO Accelerator
device. Consult the Release Notes for this IO Accelerator release before
