HP IO Accelerator Driver and Management Software Version 2.3.10 Release Notes

Errata 12
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).
Linux-specific issues
The following issues apply only to systems running Linux operating systems.
kdump crashkernel requires additional memory for the IO
Accelerator
With the IO Accelerator driver installed, kdump might fail to generate a complete dump due to a lack of
reserved memory. To ensure that you have enough memory, increase the memory allocated to the
crashkernel.
The amount of memory required varies, depending on your kernel version and the formatted sector sizes
(more RAM is required for 512B sector sizes than for 4K sectors). You can format the device sector size, using
the fio-format command. As a best practice, increase the crashkernel reserve by approximately 50
to 250 MB of RAM, depending on your configuration.
SMI-s provider registration issues when upgrading
When upgrading an existing installation of the SMI-s provider in Linux, the changes to the class schema may
not be properly detected by the provider registration scripts when using the sblim-cmpi libraries. The
provider functions normally and exposes the correct data, but the schema not updating correctly may make
it appear that the data is incorrect.
Software not installed post kernel update
When the IO Accelerator is installed for a specific kernel version and the kernel version is changed for any
reason, the VSL must be reinstalled to work with the new kernel version. RHEL5 has some processes that
minimize the need to reinstall the software after a kernel upgrade.
Rare error on driver unload using kernels older than 2.6.24
A bug in Linux kernels prior to 2.6.24 can cause a general protection fault or other kernel error when the IO
Accelerator driver is unloaded. This bug also affects non-HP drivers. The bug has been resolved in newer
kernels.
Because this is a bug in the Linux kernel, HP cannot resolve this issue for older kernels.
