Figure 5: Removing a p1228 card
5. Move the cache module from the failed p1228 card to the new card in case there is any data that has not
been written to disk.
6. Install the new p1228 card (1) and check that it is seated properly. Close the blue PCIe card retaining
latch (2).

7. Make sure the card is connected to the SuperCapacitor module and to the external SAS data storage.
8. Replace the PCI-E Riser in the server.
9. Replace the cover, as described in the HPE ProLiant Maintenance and Service guide, and power on the
server.
10. Once rebooted, the StoreOnce System will identify the new RAID controller and will remap the existing
disk storage volumes and enclosures to the controller. It will take 5 to 10 minutes for the process to
complete. During this time the product will be online but several warning events will be generated and the
GUI Event Log will show errors being reported and cleared.
11. Use the StoreOnce GUI or StoreOnce CLI to check that the firmware on the new component is correct
and upgrade, if necessary.
NOTE:
Take note of the output at command completion. It will advise if you need a system reboot or a cold
reboot to successfully install the new firmware revision.
RAID cache module and SuperCapacitor failures
About the RAID cache module and SuperCapacitor
There is one SuperCapacitor and cache module for each RAID Controller card in PCIe slot 2 and PCIe slot 3.
(This means the server node has two modules.) The RAID cache module is slotted onto the RAID card; the
SuperCapacitor is located in the center of the unit, clipped to the floor of the chassis behind the disk cage.
These items ensure cache contents are maintained after a loss of power. The LEDs on the cache module
flash when the SuperCapacitor is disconnected and POST error messages provide more information.
