Using RDR for Fault Tolerance

4-4 Express5800/320Ma: System Administrator’s Guide

ftSMC reports the capacity of physical disks and virtual disks in the Capacity property

in two different locations:

• The physical disk Capacity property appears in the ftSMC details pane under I/O

Enclosure - 10, Storage Enclosure - 40, Slot - n, Disk - n.

• The virtual disk Capacity property appears in the ftSMC details pane under

Logical Disk Information, RDR Virtual Disk - n. The virtual disk value is slightly

lower than the physical disk value because the virtual disk value is reduced by the

space reserved for metadata.

NOTE

Automatic virtual disk expansion does not work on

dynamic virtual disks; that is, RDR virtual disks that have

been converted to dynamic disks by Windows Disk

Management

Managing RDR Disks

Managing RDR-configured disks can include any of the following tasks:

• Using RDR to mirror disks in internal storage

• Enabling write caching and read-load balancing

• Setting the active RDR disk (plex)

• Deleting RDR configuration on a physical disk

• Removing a physical disk from and RDR virtual disk

• Deporting a physical disk from an RDR virtual disk

• Creating a Spare Bootable RDR Disk

• Breaking a Physical Disk from an RDR Virtual Disk

• Converting disks from dynamic to basic

• Setting or clearing the mean-time between failure (MTBF) threshold

• Resynchronizing a physical disk from the RDR virtual disk

• Setting the MTBF faultcount limit

• Making a backup of a boot disk

• Booting with a backup disk
