Managing Rdr Disks - NEC Express5800/320Ma Administrator's Manual

Using RDR for Fault Tolerance
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.

Managing RDR-configured disks can include any of the following tasks:
•
Using RDR to mirror disks in internal storage
•
Enabling write caching
•

•
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
