Breaking a Physical Disk from an RDR Virtual Disk

The following procedure isolates an RDR virtual disk plex for backup, backs up the
volumes, and then resynchronizes the broken plex with its original partner, adding it
back to the RDR virtual disk.
You cannot perform this procedure on:
•
dynamic disks
•
simplex RDR virtual disks
•
RDR virtual disks while they are resynchronizing
•
RDR virtual disks if their verify interval is set to 0; that is, if RDR verify is disabled.

that is the mirror of the system disk.
C A U T I O N
If the original boot disk is still in a system into which you
insert a spare (deported) boot disk, the original boot disk
loses its RDR configuration and is no longer an
RDR-enabled disk.
