Upgrade path
Depending on the current version of your HP IO Accelerator device, to preserve the internal structure of the
device, you might have to perform multiple upgrades. The following path is the minimum upgrade path that
you must follow. Upgrade the HP IO Accelerator VSL software on the system, and upgrade the firmware to
the compatible version in the following order:
1.2.4 > 1.2.7 > 2.1.0 > 2.2.3 > 3.2.x
For VSL upgrade information for the HP IO Accelerator, see the HP IO Accelerator Release Notes on the HP
website ( http://www8.hp.com/us/en/support-drivers.html ). General upgrade instructions, including the
firmware update instructions, are available in the HP IO Accelerator User Guide for each operating system.
Overformatting not supported
The –o overformat option is not supported in the 3.x.x VSL software. All upgraded HP IO Accelerator
devices are formatted to the maximum advertised capacity, regardless of whether the device was
overformatted prior to the upgrade.
Upgrading procedure
Be sure to follow the upgrade path and make sure that all previously installed IO Accelerator devices are
updated with the appropriate 3.2.3-compatible firmware.
If you plan to use IO Accelerator Gen1 devices and IO Accelerator Gen2 devices in the same host, perform
this upgrade on all existing IO Accelerator Gen1 devices before installing the new IO Accelerator Gen2
devices.
1. Prepare each existing IO Accelerator device for upgrade:
a. Backup user data on each IO Accelerator device.
CAUTION: Upgrading IO Accelerator devices that were previously configured for VSL 1.x.x or
2.x.x to work with VSL 3.x.x requires a low-level media format of the device. No user data is
maintained during the media format process. Be sure to backup all data on your IO Accelerator
device as instructed before upgrading the firmware.
Do not back up the data onto another IO Accelerator device on the same system. The backup must
be to a local disk or to an externally attached volume.
b. Run the fio-bugreport command-line utility and save the output. This output captures the device
information for each device in the system. This device information will be useful in troubleshooting
any upgrade issues. For example:
fio-bugreport
c. Detach the IO Accelerator devices. For example:
fio-detach /dev/fct*
For more information, see "fio-detach (on page
42 )."
2. Unload the current IO Accelerator driver. For example:
$ modprobe -r iomemory-vsl
3. Uninstall the 2.x HP IO Accelerator VSL software.
a. To uninstall the software, specify the kernel version of the package you are uninstalling. Run the
following command to find the installed packages:
$ rpm -qa | grep -i iomemory
