If you want information about all virtual disks, use the allVirtualDisks parameter. You can also request information about a specific target virtual disk. The following example is the script file version of the command: show virtualDiskCopy source ["Jaba_Hut"]; Changing Virtual Disk Copy Settings The set virtualDiskCopy command enables you to change the property settings for a virtual disk copy pair. Using this command, you can change the following items: • Copy priority • Read/write permission for the target virtual disk Copy priority has five relative settings, which range from highest to lowest. The highest priority supports the virtual disk copy, but I/O activity might be affected. The lowest priority supports I/O activity, but the virtual disk copy takes longer. You can change the copy priority at three different times in the operation: • Before the virtual disk copy begins • While the virtual disk copy has a status of In Progress • After the virtual disk copy has completed re-creating a virtual disk copy using the recopy virtualDiskCopy command When you create a virtual disk copy pair and after the original virtual disk copy has completed, the target virtual disk is automatically defined as readonly to the hosts.
