Using RDR for Fault Tolerance

Removing a Physical Disk from an RDR Virtual Disk

!
Executing the Remove a Physical Disk from RDR Virtual Disk command on a
partnered (duplex) RDR virtual disk (comprising two physical disks):
•
Erases all of the data on the disk, including all Windows Disk Management , and
all RDR metadata.
•
Returns the physical disk to a basic, non-RDR-configured, blank disk.
The system does not warn you when you issue this command because the target disk
has a surviving partner physical disk that still contains all of the data. For that reason,
the system does not need to restart.
If you execute the Remove a Physical Disk from RDR Virtual Disk command on an
unpartnered (simplex) RDR virtual disk (comprising one physical disk), the system
prompts you to remove all partition and volume data on the disk before the command
can continue. The prompt alerts you that this operation may result in the loss of all data
on this virtual disk since there is only one physical disk.
You cannot remove:
•
The only unmirrored boot disk
•
The only unmirrored disk containing a paging file
•
An unmirrored disk containing data
•
A resynchronizing disk
To remove a physical disk from an RDR virtual disk
1. In ftSMC, right-click the target disk.
2. Select Remove Physical Disk from RDR Virtual Disk.
