5 The HP SmartArray P410i and P41 1 RAID controllers and
HP SAS expander card (HP D2D4312)

Overview

The HP D2D4312 has three RAID controllers.
The P410i RAID controller is integral to the DL370G6 motherboard and is used to control the
12 hard disk drives internal to the HP D2D4312 via the HP SAS Expander card in slot 1.
The two P41 1 cards are used to connect the external storage shelves to the D2D 4312 and
are located in PCI-e slots 5 and 6.
Each P410i and P41 1 RAID controller is fitted with 512 MB RAM and one 512 MB FBWC
(Flash Backed Write Cache).
NOTE: If you replace a motherboard with integral P410i card, or a P41 1 card, you must add
the RAID 6 license for the card, as described in the relevant sections below.

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 P41 1 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
