Virtual Disk Copy
Virtual Disk Copy generates a full copy of data from the source virtual disk to
the target virtual disk in a storage array. You can use Virtual Disk Copy to back
up data, copy data from disk groups that use smaller-capacity physical disks to
disk groups using greater-capacity physical disks, or restore Snapshot Virtual
Disk data to the source virtual disk.
To create a Virtual Disk Copy of a Microsoft Cluster shared disk:
1 Create a Snapshot Virtual Disk using the cluster shared disk as a source
disk.
2 Do not map that Snapshot Virtual Disk to any cluster node. Then, use
the newly created Snapshot Virtual Disk as the source disk for the
Virtual Disk Copy.
NOTE:
shared disk directly, the operation fails and the following error is displayed:
The operation cannot complete because the selected
virtual disk is not a source virtual disk
candidate.
If the cluster shared disk fails and you want to restore it from the target virtual
disk, use Failover Cluster Manager to change the status of the cluster group
containing the failed disk to offline. Use one of the following methods:
• Use Virtual Disk Copy to transfer the data from the target virtual disk to
the cluster shared disk.
• Unassign the cluster shared disk from the host group and map the target
virtual disk to the host group.
Remote Replication
Remote Replication is a storage array premium feature that provides online,
real-time replication of data between storage arrays. When this feature is
activated, a dedicated port (port 3) on each RAID controller is reserved
exclusively for Remote Replication traffic. No other data traffic is allowed on
that port until the Remote Replication feature is deactivated. A dedicated
zone on each Fibre Channel switch is also required. For cabling examples,
configurations, host bus adapter (HBA) installation and zoning, see
Configuring Fibre Channel with the Dell MD3600f Series Storage Array at
