HP IO Accelerator Driver 3.1.1 Release Notes

Errata 14
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.
Compiler Cache causes driver src.rpm rebuild failures on some
distributions
If the ccache package is installed, rebuilding the IO Accelerator driver src.rpm might fail with an error
similar to the following:
CC [M]
/root/fio/iomemory-vls-<version>/root/usr/src/iomemory-vsl/driver_init.o
/root/fio/iomemory-vls-<version>/root/usr/src/iomemory-vsl/driver_init.c:116
:
error: initializer element is not constant
[...]
To enable the driver to rebuild, remove the ccache package or disable ccache.
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).
Management SDK requires a specified path
To build off of the Management SDK for this release, you must specify the -L/usr/lib/fio linker path in
your makefiles.
