Creating a Virtual Disk Copy
When the Virtual Disk Copy premium feature is enabled on a storage array managed by the vCenter Plug-in,
the Virtual Disk Copy tab appears next to the Mappings tab. This tab allows the management of virtual disk
copies on the selected storage array. See Figure 35.
Figure 35. Virtual Disk Copy Management
From this tab, all virtual disk copy operations are displayed along with the current status of all virtual disk
copies. From the Commands area, the following options are available: Create Virtual Disk Copy, Recopy, Stop,
Change Virtual Disk Copy Parameters, Remove Copy, and Refresh. To create a new virtual disk copy, click
Create Virtual Disk Copy in the Commands area, which launches the Virtual Disk Copy wizard. From this
wizard, select the source virtual disk to use for the virtual disk copy.
NOTE: While the virtual disk copy is being established, the source virtual disk is read-only to the host to
which the virtual disk copy is presented. When the Snapshot premium feature is enabled, the vCenter
Plug-in uses the feature to create a snapshot of the source virtual disk before the virtual disk copy is
initiated and the virtual disk copy operation uses the snapshot virtual disk to establish the virtual disk
copy with. This allows for continued read-write operations to the source virtual disk from the host during
the establish period.
