WARNING! To reduce the risk of personal injury or damage to the equipment, consult the safety
information and user documentation provided with the server and p1224 controller before attempting
the installation.
Identifying a RAID controller failure
All HP StoreOnce Backup systems boot from a p1224 RAID controller that is also connected to
some or all of the customer data storage disks. If a catastrophic failure of the boot RAID controller
occurs, the system will not boot. This may only be diagnosed from the server POST messages where
the controller may report an error or a lockup code. In these cases contact HP Support and provide
information about the reported error code.
Other forms of non-catastrophic RAID controller failure, or failure of the second RAID controller on
the StoreOnce 4700 Backup, will be reported in the Event Log and Hardware Problem Report on
the StoreOnce GUI.
NOTE: If RAID fails and the HP StoreOnce Backup System is still functioning, you can also get
information, including license keys, by generating a Support ticket.
Replacing the HP p1224 controller
IMPORTANT: When replacing the p1224 controller be sure to always replace the card into the
same slot from which it was removed. Make sure the card is connected to the SuperCapacitor
module and to the internal and external SAS data storage.
1. Power off the HP StoreOnce Backup system and, observing the safety and antistatic procedures
documented in the HP ProLiant Servers user guides, remove the cover from the HP StoreOnce
Backup system, as described in the appropriate HP ProLiant Maintenance and Service Guide.
2. Locate the p1224 controller card and detach the cables connecting it to the SuperCapacitor,
and the internal and external SAS storage. (The StoreOnce 4700 Backup has two RAID cards;
be sure to identify which slot contains the failed card.)
3. Unclip the blue retaining latch on the PCIe card (1 and 2) and remove the PCIe card (3).
