HP IO Accelerator Driver and Management Software 2.2.0 Release Notes
Errata 14
Reported power usage from fio-status might be incorrect for IO
Accelerator Monos
The value reported by the fio-status utility for PCIe Bus power is incorrect for IO Accelerator
Monos (IO Accelerators without a separate carrier adapter) and must not be used for any health
monitoring. The IO Accelerator Mono cannot draw more power than what is provided by the base PCIe
specification for the minimum slot. Therefore, tracking this value accurately is unnecessary. The device
and driver operate normally in all other aspects. Only the reporting function is affected. Other IO
Accelerator models that support power usage monitoring are not affected.
Sample errant fio-status output: PCIE Bus power:
PCIE Bus power: avg 6.86W, max -16.89W
fio-status -a displays incorrectly for the
On the HP IO Accelerator for BladeSystem c-Class, fio-status –a displays the following information:

The Powerloss protection: not available message is used to guarantee data in process is
written to the NAND flash in the case of a catastrophic power loss. Most power loss scenarios are met by
the c-Class enclosure power loss protection and the blade server design provisions.
PCIe slot available power and sufficient power available fields do not apply for the IO Accelerator for
BladeSystem c-Class. Sufficient power is provided to the IO Accelerator.
LED indicators do not operate properly
The LED lights might not light up according to expected behavior. After the driver is loaded, the amber
and green LED lights might remain constantly lit and fail to blink to indicate device activity.
This behavior is only experienced on newer IO Accelerator devices that have a part number that begins
with FS1-003-XXX-XX. Older IO Accelerator devices that are not affected by this behavior have a part
number that begins with FS1-001-XXX-XX.
