db1089 had a controller issue (T166933) and during the startup it said:
Slot 1 Port 1 : Smart Array P840 Controller - (4096 MB, V3.56) 1 Logical Drive(s) - Operation Failed - 1719-Slot 1 Drive Array - A controller failure event occurred prior to this power-up. (Previous lock up code = 0x13) Action: Install the latest controller firmware. If the problem persists, replace the controller. Important information available or errors detected Press 'ESC+1' to continue, or 'ESC+2' for more information
It will be good to upgrade its firmware to the latest, so if it crashes again we can at least say to HP that the firmware was upgraded after the first crash.
