Using the Virtual Disk Copy Feature 85The following example is the script file version of the command:set virtualDiskcopy target ["Obi_1"] copyPriority=highest targetreadonlyenabled=false;Recopying a Virtual DiskCAUTION: The recopy virtualDiskCopy command overwrites existing data on thetarget virtual disk and makes the target virtual disk read-only to hosts. The recopyvirtualDiskCopy command fails all snapshot virtual disks associated with thetarget virtual disk, if any exist.Using the recopy virtualDiskCopy command, you can create a new virtualdisk copy for a previously defined copy pair that has a status of Stopped,Failed, or Completed. Use the recopy virtualDiskCopy command to createbackups of the target virtual disk, then copy the backup to tape for off-sitestorage. When using the recopy virtualDiskCopy command to make abackup, you cannot write to source while the recopy is running. The recopymight take a long time.When you run the recopy virtualDiskCopy command, the data on the sourcevirtual disk is copied in its entirety to the target virtual disk.Reset the copy priority for the recopy operation by using the recopyvirtualDiskCopy command. The higher priorities allocate storage arrayresources to the virtual disk copy at the expense of storage array performance.Preparing Host Servers to Recopy a Virtual DiskCAUTION: Before you create a new copy of a source virtual disk, stop any dataaccess (I/O) activity or suspend data transfer to the source virtual disk (and, ifapplicable, the target disk) to ensure that you capture an accurate point-in-timeimage of the source virtual disk. Close all applications, including WindowsInternet Explorer, to make sure all I/O activity has stopped.NOTE: Removing the drive letter of the associated virtual disk(s) in Windows orunmounting the virtual drive in Linux helps to guarantee a stable copy of the drivefor the virtual disk copy.Before creating a new virtual disk copy for an existing copy pair, both theserver and the associated virtual disk you are recopying have to be in theproper state. To ensure that the host server is properly prepared to create avirtual disk recopy, you can either use an application to carry out this task, oryou can perform the following steps:
