Splitting a VDisk copy

You can create a separate virtual disk (VDisk) by splitting a synchronized VDisk copy. You can select a copy to split off from the VDisk and set its attributes.

1. Click Work with Virtual Disks > Virtual Disks. The Viewing Virtual Disk panel is displayed.
2. Select a VDisk that contains copies and select Split a VDisk Copy from the task list and click Go. The Split a Copy from VDisk panel displays.
3. Select the VDisk copy that is displayed in the table to create a new VDisk.
4. Enter a name for the new VDisk.
5. Select the Force Split option to force the split to proceed even though the copy you are trying to split is not synchronized.
   Note: If you select this option, the split copy might not be point-in-time consistent.
6. Select the I/O group for the new VDisk that you are creating from the VDisk copy. By default, the VDisk is created in the same I/O group as the VDisk that the copy is split from.
7. Select the preferred node for the new VDisk that you are creating from the VDisk copy. When you let the system choose the preferred node, the system performs workload balancing by managing the I/O traffic for the VDisks across multiple nodes.
8. Select the cache mode for the new VDisk that you are creating from the VDisk copy.
9. Optional: Enter a unit device identifier for the new VDisks in the Unit Device Identifier field. This field is used only by hosts that are using the OpenVMS operating system. For other operating systems, setting a unit device identifier is not required.
10. Click OK.
