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 Setting the targetReadOnlyEnabled parameter to TRUE means that write requests cannot be made to the target virtual disk. This setting also ensures that the data on the target virtual disk remains unaltered. Refer to steps 1 through 4 in the preceding section, "Preparing Host Servers to Create a Virtual Disk Copy" on page 80. The following example is the script file version of the command: create virtualDiskcopy source="Jaba_Hut" target= "Obi_1" copyPriority=medium targetreadonlyenabled= true; After the virtual disk copy operation is completed, the target virtual disk automatically becomes read-only to the hosts. Any write requests to the target virtual disk are rejected, unless you disable the read-only attribute. Use the set virtualDiskCopy command to disable the read-only attribute. Viewing Virtual Disk Copy Properties Using the show virtualDiskCopy command, you can view information about one or more selected source virtual disks or target virtual disks.
