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 will be read only to all I/O activity. Any write attempts to the source virtual disk will fail until the operation completes. Once the virtual disk copy operation is completed register the target virtual disk with the OS 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. Refer to steps 1 through 4 in the preceding section, "Preparing Host Servers to Create a Virtual Disk Copy" on page 80. The create virtualDiskCopy command might look like the following example: client>smcli 123.45.67.89 -c "create virtualDiskcopy source=\"Jaba_Hut\" target= \"Obi_1\" copyPriority=medium targetreadonlyenabled=true" The command in this example copies the data from the source virtual disk named Jaba_Hut to the target virtual disk named Obi_1. Setting the copy priority to medium provides a compromise between the following storage array operations: • The speed with which the data is copied from the source virtual disk to the target virtual disk • The amount of processing resource required for data transfers to other virtual disks in the storage array Using the Virtual Disk Copy Feature 81
