Configuration: Premium Feature—Virtual Disk Copy 171
Virtual Disk Read/Write Permissions
After the virtual disk copy is complete, the target virtual disk automatically
becomes read-only to the hosts. The target virtual disk rejects read and write
requests while the virtual disk copy operation has a status of Pending or In
Progress or if the operation fails before completing the copy. Keep the target
virtual disk Read-Only enabled if you want to preserve the data on the target
virtual disk for reasons such as the following:
• If you are using the target virtual disk for backup purposes.
• If you are using the data on the target virtual disk to copy back to the
source virtual disk of a disabled or failed snapshot virtual disk.
If you decide not to preserve the data on the target virtual disk after the
virtual disk copy is complete, change the write protection setting for the
target virtual disk to Read/Write.
