Initializing thin virtual disk with same physical capacity

CAUTION: Initializing a thin virtual disk erases all data from the virtual disk.

You can create thin virtual disks only from disk pools, not from disk groups.
By initializing a thin virtual disk with the same physical capacity, the original repository is maintained but the contents of the thin virtual disk are deleted.

In the AMW, select the Storage & Copy Services tab.
Select the thin virtual disk that you want to initialize.
The thin virtual disks are listed under the Disk Pools node.
Select Storage > Virtual Disk > Advanced > Initialize.
The Initialize Thin Virtual Disk window is displayed.
Select Keep existing repository, and click Finish.
The Confirm Initialization of Thin Virtual Disk window is displayed.
Read the warning and confirm if you want to initialize the thin virtual disk.
Type yes, and click OK.
The thin virtual disk initializes.
