Replacing The Raid Components; P1224 Raid Controller - HP StoreOnce 3100 Maintenance And Service Manual

NOTE:
If RAID fails and the HPE StoreOnce System is still functioning, you can also get information, including
license keys, by generating a Support ticket.

Replacing the RAID components

When replacing the p1224 controller or SAS expander card, be sure to replace the card into the same slot
from which it was removed. Make sure that the card is connected to the SuperCapacitor module and to the
internal SAS data storage. On an HPE StoreOnce 5100 System, if the system has been expanded, also
connect the card to the external SAS storage.
CAUTION:
To reduce the risk of personal injury or damage to the equipment, consult the safety information and
user documentation provided with the server and RAID component before replacing it.
