3 Remove the drive letter(s) of the source and (if mounted) virtual disk in Windows or unmount the virtual drive(s) in Linux to help guarantee a stable copy of the drive for the virtual disk. If this is not done, the copy operation reports that it has completed successfully, but the copied data is not updated properly. 4 Follow any additional instructions for your operating system. Failure to follow these additional instructions can create unusable virtual disk copies. NOTE: If your operating system requires additional instructions, you can find those instructions in your operating system documentation. After your server has been prepared, see "Copying the Virtual Disk" on page 81 to copy the virtual disk. Copying the Virtual Disk After first preparing the host server(s) as specified in the preceding procedure, use the following examples to make a virtual disk copy. The following syntax is the general form of the command: create virtualDiskCopy source="sourceName" target= "targetName" [copyPriority=(highest | high | medium | low | lowest) targetReadOnlyEnabled=(TRUE | FALSE)] NOTE: Use one or both of the optional parameters as needed to help define your configuration. It is not necessary to use any optional parameters. Once the virtual disk copy has started, the source virtual disk is read only to all I/O activity. Any write attempts to the source virtual disk fails until the operation completes. Once the virtual disk copy operation is completed register the target virtual disk with the operating system to be used by performing the following steps: • Enable write permission on the target virtual disk by either removing the Virtual Disk Copy Pair or explicitly setting write permission. - In Windows, assign a drive letter to the virtual disk. - In Linux, mount the virtual disk. See step 1 to step 4 in "Preparing Host Servers to Create a Virtual Disk Copy" on page 80. Using the Virtual Disk Copy Feature 81
