Hello Terence,

what is the array controller's firmware release? There is an issue with certain controllers and firmware versions, that report a low battery charge and as result disable the accelerator.

Regards, klaus

The latest firmware revision for SmartArray 6i / 640x cards is a critical update, with the following fixes:

Version 2.48A (Contains Major Bug Fixes)
Fixes
Fixed an interrupt handling issue that can cause server reboot when using Microsoft Remote Installation Services (RIS).
Updated the battery charging firmware to reduce the frequency and duration of battery charging cycles. This helps prevent overcharging the battery, which can contribute to premature battery failures. This also reduces the time required for a battery recharge cycle to complete.
Updated the battery firmware to improve the sensing and reporting of battery health. This helps prevent battery status messages from alternating or indicating false status.
Updated the battery firmware to reduce the chances of deep discharging the battery. This helps to maintain the capacity of the battery in the event data was trapped in the cache over the specified backup duration.
Updated the battery firmware to keep the charge capacity during a controller firmware update. This helps prevent the inconvenience of battery back write cache becoming temporarily disabled due to a required recharge following a battery firmware update.

We have seen a large number of battery failures here, but none since this firmware update was applied. Here's the link for the 6400 firmware (if you don't use Version Control): http://h18000.www1.hp.com/support/files/server/us/download/23526.html
