HP IO Accelerator Driver and Management Software Version 3.2.3 Release Notes

Errata 21
If you use a set of utilities that does not match the IO Accelerator VSL software, you might see an error in the
command line or logs such as unhandled ioctl or Error: This version of <utility> is not
compatible with the running driver. To solve this issue, reinstall the utilities using the package with
the correct version number.
Utility failed while running fio-bugreport
The fio-bugreport utility uses other utilities to create the report. Depending on the operating system,
some of these additional utilities might not be available and the fio-bugreport displays an error that a
fio utility failed or was not found.
The fio-bugreport utility is designed to continue even if a component fails. The report is still created.
Do not run fio-status during driver load
Run the fio-status utility after the driver has loaded and not during driver load. Running the
fio-status utility while the driver is loading might result in the following message:
Missing MIDS. Coming up in minimal mode.
If you receive this message while running the fio-status utility during driver loading, unload and reload
the driver, and then run the fio-status utility after the driver has loaded.
fio-status might not display failed devices
When an IO Accelerator device fails, occasionally, it does not appear in the fio-status report. If your
device has failed, contact HP support (http://www.hp.com/go/assistance).
Windows-specific issues
fio-trim-config returns Unknown status
The fio-trim-config utility returns Unknown status on Windows Server 2008 R2, Windows 7, and
Windows Server 2012. Windows Server 2008 R2, Windows 7, and Windows Server 2012 have native
TRIM support and therefore do not use this utility. While you should only use this utility with Windows Server
2003, you will not harm the system by running it on newer versions of Windows, and you can safely ignore
the Unknown status if you do run it on a later version.
Specific partitions required for devices with capacities greater
than 2 TB
Devices with capacities greater than 2 TB, such as the 3.0 TB MLC ioDrive2 device, require the following
partition types:
• Single device: GPT (GUID Partition Table)
• Multiple devices (for a RAID configuration): Dynamic Disk
These devices also require sector sizes greater than 512 B (HP recommends 4 KB sectors). When you format
these devices using fio-format, the default sector size is 4 KB.
