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 RAID controllers before attempting the installation.

Part numbers

The P410i card is integral to the motherboard, which is the standard motherboard.

The required part for the P812 card is: HP Smart Array P812/1024 MB with FBWC Controller: 487204-B21

The required part for the P411 card is: HP Smart Array P411/512 MB with BBWC Controller: 462832-B21

Identifying a RAID contoller failure

RAID card failures are reported in the Log and in email alerts, if you have set them up. For example: cache module failure.

You can identify which card has failed by looking at the Storage-RAID pages of the Web Management Interface. The P410i card is identified as “internal”; the P812 or P411 cards are identified by their slot number in the Controllers section. Any issues with logical units on this page also indicate a problem.

If the HP SAS expander card is at fault, disks will not be visible on the Storage-Shelves tab

NOTE: If RAID fails and the HP D2D Backup System is still functioning, you can also get information, including license keys, by generating a Support ticket (from the Administration-Support web page).

Before replacing a RAID controller — a note about licenses

The Smart Array Advanced Pack (SAAP) is required to enable RAID 6 support. You must reinstate the SAAP license, if you replace the motherboard/P410i on the HP D2D4324 or HP D2D4312 products or if you replace one of the P411 cards on an HP D2D4312 product. (You do not need to reinstate the license, if you replace one of the P812 cards on an HP D2D4324 product.)

If you do not reinstate the license, the system will experience one of the following symptoms :

•Very slow product performance (Running as RAID 5 access to the disks, if the arrays had not failed themselves)

•Refusal to create the storage (if the storage arrays have failed and need to be rebuilt from scratch)

NOTE: It is not necessary to reinstate the license with the P812 card.
