Upgrading devices for IO Accelerator VSL 2.x.x to 3.x.x

This version of IO Accelerator VSL software supports new features, including the latest generation of IO Accelerator architecture and improved Flashback protection. These features require the latest version of the IO Accelerator firmware. Every device in a system running 2.x or later must be upgraded to the latest version of the firmware.

For example, if you have a system running 2.x.x IO Accelerator VSL software with devices previously installed and you want to install new devices that require the latest version of the firmware, then you must upgrade all of the existing devices to the latest firmware version.

CAUTION: You cannot revert device firmware to an earlier version after you have upgraded the device without voiding your warranty. If you experience problems with your upgrade, contact HP Customer Support.

CAUTION: Upgrading devices (previously configured for VSL 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 process. Be sure to back up all data as instructed.

Multiple upgrade passes for some versions

Depending on the current firmware version of your devices, you may need to upgrade your device's firmware multiple times to preserve internal structures. See the IO Accelerator VSL software for the upgrade path.

Upgrade 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. Back up 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.
