Step 8: Set Dual Disk Configuration; Setting Dual Disk Configuration By Rdr (Rapid Disk Resync) Function - NEC N8800-103F User Manual

Step 8: Set Dual Disk Configuration

NEC Express5800/ft series secures data by setting dual disk configuration using "RDR (Rapid Disk
Resync) function." Be sure to make dual disk settings by referring to the procedure.
IMPORTANT:
•
Set dual disk configuration by the RDR (Rapid Disk Resync) function. If you want to use
other disk management tool (e.g. VERITAS Storage Foundation), install it after "Step 14:
Make Settings for Failure Management." If you perform this operation with a tool other
than the RDR (Rapid Disk Resync), a mirror synchronization gap may occur when the
system is rebooted.
•
CPU/IO module has a processor function part and IO function part, and monitors and
manages each part. The IO function part is referred to as PCI module in this section.
Setting Dual Disk Configuration by RDR (Rapid Disk Resync)
function
This device sets dual configuration for each disk by the RDR function of the ft control software.
By setting RDR, as the following figure and table show, dual configuration is set between the disks
of the corresponding slots, and these disks are recognized as one virtual disk by Windows (such as
Disk Management and Device Manager).
