Mirroring Dynamic Disks with RDR
This procedure turns dynamic disks into basic disks before mirroring them with RDR.
To use RDR to mirror dynamic disks themselves, see Chapter 3 in the
Express5800/320Ma: Software Installation and Configuration Guide.
Mirroring a dynamic disk with RDR involves two steps:
•
Converting
the disk to basic
•
Upgrading
the disk to RDR

!
Converting a dynamic disk to a basic disk removes all
data from the disk. So that you can recover the data, back
it up to backup media before you convert the disk to a
basic disk.
1. Right-click My Computer, and click Manage.
2. Expand Computer Management and Storage.
3. Click Disk Management.
4. Right-click the icon of the target disk in the lower portion of the Disk Management
details pane.
5. Select Convert to Basic Disk.
6. If necessary, recover the information from backup media.
To upgrade the basic disks to RDR, see
“Notes on Using RDR to Mirror Disks in
Internal Storage” on page 4-5
.
Setting the Active RDR Disk (Plex)
The Set As Active RDR Plex command makes the physical disk on which this
command is issued the "active" disk. The active disk is the disk:
•
From which data is read
•
From which a partner disk is resynchronized
