• If hosts are mapped to the source virtual disk, the data that is copied to the target virtual disk when you perform the re-copy operation might have changed since the previous virtual disk copy was created. • Select only one virtual disk copy in the Copy Manager dialog. CAUTION: Possible loss of data-The re-copying operation overwrites existing data on the target virtual disk. CAUTION: Possible loss of data access-While a virtual disk copy has a status of In Progress or Pending, source virtual disks are available for read I/O activity only. Write requests are allowed after the virtual disk copy has completed. To recopy the virtual disk: 1. Stop all I/O to the source virtual disk and the target virtual disk. 2. Unmount any file systems on the source virtual disk and the target virtual disk. 3. In the AMW, select Copy Services → Virtual Disk Copy → Manage Copies. The Copy Manager window is displayed. 4. Select the copy pair in the table. 5. Select Copy → Re-Copy. The Re-Copy window is displayed. 6. Set the copy priority. There are five copy priority rates available: lowest, low, medium, high, and highest. If the copy priority is set at the lowest rate, I/O activity is prioritized, and the virtual disk copy takes longer. If the copy priority is set to the highest priority rate, the virtual disk copy is prioritized, but I/O activity for the storage array might be affected. Removing Copy Pairs You can remove one or more virtual disk copies by using the Remove Copy Pairs option. Any virtual disk copy-related information for the source virtual disk and the target virtual disk is removed from the Virtual Disk Properties dialog and the Storage Array Profile dialogs. When you remove a virtual disk copy from the storage array, the Read-Only attribute for the target virtual disk is also removed. After the virtual disk copy is removed from the Copy Manager, you can either select the target virtual disk as a source virtual disk or the target virtual disk for a new virtual disk copy. If you remove a virtual disk copy, the source virtual disk and the target virtual disk no longer appear in the Copy Manager. Keep these guidelines in mind when you remove copy pairs: • Removing copy pairs does not delete the data on the source virtual disk or target virtual disk. • If the virtual disk copy has a status of In Progress, you must stop the virtual disk copy before you can remove the copy pair. To remove copy pairs: 1. In the AMW, select Copy Services → Virtual Disk Copy → Manage Copies. The Copy Manager window is displayed. 2. In the table, select one or more copy pairs. 3. Select Copy → Remove Copy Pairs. The Remove Copy Pairs dialog is displayed. 4. Click Yes. 117
