Identifying a RAID controller failure

All HPE 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 HPE Support and provide information
about the reported error code.
For other forms of non-catastrophic RAID controller failure, or failure of the second RAID
controller on the StoreOnce 4700 Backup, look at the Event Log and Hardware Page on the
StoreOnce GUI.
If RAID fails and the HPE StoreOnce Backup System is still functioning, you can also get
information, including license keys, by generating a Support ticket.

Replacing the HP p1224 controller

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.
CAUTION:
information and user documentation provided with the server and p1224 controller before replacing
the p1224 controller.
1. Power off the HPE StoreOnce Backup system and, observing the safety and antistatic
procedures documented in the HPE ProLiant Servers user guides. Remove the cover from
the HPE StoreOnce Backup system, as described in the appropriate HPE 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. As shown in the following figure, unclip the blue retaining latch on the PCIe card (1 and 2)
and remove the PCIe card (3).
