HP IO Accelerator Driver and Management Software Version 3.2.3 Release Notes

devices, see the HP IO Accelerator Hardware Installation Guide.
Proper time on startup
If the IO Accelerator device does not boot up with the proper time set on the system, then the software might
delay starting, because the driver self-tunes to the difference between the reflected age data and actual age
of data.
If the time is set backward on a running system, this setting might result in decreased card performance for
the lesser of one day or the amount the time is set backward.
Proper time is within a few minutes of actual time.
Firmware update might fail with a TDO mismatch error
An IO Accelerator device firmware upgrade might fail with the following error:
ERROR: TDO mismatch
This error generally occurs when upgrading multiple devices at the same time.
To resolve this issue, update the devices again, but perform the update one device at a time. For IO
Accelerator Duo devices, upgrade each IO Accelerator device (on the duo product) individually.
Do not reboot the system until the devices have been successfully updated.
Device capacity might change after upgrade
If you upgrade a device that was previously formatted using a much earlier version of IO Accelerator VSL
software, then the device capacity might change. The capacity difference might be minimal (for example,
160.94 GB becomes 160 GB), but it can be an issue if the device was part of an application or database
that expects the same capacity.
To solve this issue, use the -o (overformat) option with fio-format. For example:
fio-format -o 160940M /dev/fct1
Management-specific issues
Do not run multiple fio-format commands in parallel
HP does not recommend running multiple instances of fio-format commands at the same time. If you run
multiple commands in parallel, one or more of the commands might fail, which can cause the device to fail.
To avoid this issue, either run multiple commands in sequence or, if you are formatting all devices to the same
settings, specify multiple devices within one command.
Be sure the utilities match the IO Accelerator VSL software version
When you install this version of the IO Accelerator VSL software, be sure that you install the utilities that go
with this version. Each set of utilities is designed to work with a specific version of the IO Accelerator VSL
software.
