Step 8: Set Dual Disk Configuration - NEC Express5800/320Fd-LR User Manual

Step 8: Set Dual Disk Configuration

At this point, CPU/IO module 1 - Slot 1 and CPU/IO module 0 - Slot 1 have been duplex.
Except when a disk has been added or RAID has been reconfigured, check if the duplication has
succeeded and perform "Step 9: Connect and Configure Options".
NEC Express5800/ft series secures data integrity by setting dual disk configuration using
"Software-RAID." The section describes procedures to configure disks.
IMPORTANT:
Execute Disk settings and configure dual disk when a new hard disk drive is added.
Disk Configuration
RAID must be configured for all the internal disks in NEC Express5800/ft series. For NEC
Express5800/ft series, RAID 1 is configured by software.
RAID is configured by hard disk drives pairing the slot 1 of CPU/IO module 0 and the slot 1 of
CPU/IO module 1, the slot 2 of CPU/IO module 0 and the slot 2 of CPU/IO module 1, and the slot 3
of CPU/IO module 0 and the slot 3 of CPU/IO module 1.
