HP IO Accelerator Driver and Management Software Version 2.3.10 Release Notes

Errata 11
Errata
Errata overview
This section describes issues you might encounter when using the 2.3.10 IO Accelerator driver release.
General issues
The following issues might occur regardless of which operating system you use.
Incorrect reserves indicated in fio-status
When an IO Accelerator device is in write-reduced mode (due to diminished reserves), the fio-status
utility may erroneously report 100% health reserves.
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.
Periodic latency bump
A latency bump every 30 seconds might be observed under some workloads, or a higher than expected
average latency might be observed. This issue occurs because of normal maintenance.
Under Linux, this bump can be safely changed to happen every minute instead of every 30 seconds. To set
a one minute interval, enter the following command every time you load the driver:
$ echo 60000 > /proc/fusion/fio/fiox/data/groomer/groom-oldest-lebinterval
where x is the letter of the device you are modifying.
This issue will be resolved in a future release.
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.
