HP IO Accelerator Driver and Management Software 2.2.0 Release Notes

Errata 17
Windows-specific issues
The following issues apply only to systems running Windows® operating systems.
Windows operating systems find an old driver in the
Windows\system32\driver directory
If all previous versions of the IO Accelerator software and driver have not been uninstalled, Windows
operating systems might find an older driver in Windows\system32\driver directory. If this has
happened:
• The New hardware installed message does not display after removing the previous version
and rebooting.
• When you open the Control Panel, no driver revision is displayed for the IO Accelerator. The IO
Accelerator displays as a Mass Controller device.
To fix this issue:
1. Open to the Control Panel and remove the driver.
2. Reboot the system.
Conversion to GPT or Dynamic disk terminates Logical Disk
Manager Administrative Service
This issue appears when:
• Converting a Basic partition to GPT
• Converting a Basic partition to Dynamic Volume
• Switching between GPT and Dynamic Volume or vice versa
When an issue occurs, the following message appears: The Logical Disk Manager
Administrative Service terminated unexpectedly. Restart the Virtual Disk
service.
This issue occurs only with Windows Server® 2003 and Windows® XP x64.
If the IO Accelerators are used in GPT or Dynamic mode, the following process must be performed during
the initial setup. This process also recovers drives that have had a failed conversion attempt.
CAUTION: This procedure destroys any existing data on your drives. If you already have data
on a drive, be sure to back it up before proceeding.
For IO Accelerators used in GPT or Dynamic mode:
1. For each IO Accelerator in the system to be converted, use the HP IO Accelerator Management Tool
to
a. Detach the drive.
b. Perform a low-level format.
For more information, see the User Guide that came with your IO Accelerator.
2. Restart the computer.
