to the target virtual disk after the virtual disk copy is created. Maintain the read-only status when the following conditions apply: • You are using the target virtual disk for backup purposes • You are copying data from one disk group to a larger disk group for greater accessibility • You are planning to use the data on the target virtual disk to copy back to the source virtual disk in case of a disabled or failed snapshot virtual disk At other times you might want to write additional data to the target virtual disk. You can use the set virtualDiskCopy command to reset the read/write permission for the target virtual disk. NOTE: If you enabled host writes to the target virtual disk, read and write requests are rejected while the virtual disk copy has a status of In Progress, Pending, or Failed. The following syntax is the general form of the command: set virtualDiskCopy target [targetName] [source [sourceName]] copyPriority=(highest | high | medium | low | lowest) targetReadOnlyEnabled=(TRUE | FALSE) NOTE: Use one or both of the parameters as needed to help define your configuration. It is not necessary to use either parameter. The following example shows how to change parameters using the set virtualDiskCopy command: client>smcli 123.45.67.89 -c "set virtualDiskcopy target [\"Obi_1\"] copyPriority=highest targetreadonlyenabled=false;" The following example is the script file version of the command: set virtualDiskcopy target ["Obi_1"] copyPriority= highest targetreadonlyenabled=false; Recopying a Virtual Disk NOTICE: The recopy virtualDiskCopy command overwrites existing data on the target virtual disk and makes the target virtual disk read-only to hosts. The recopy virtualDiskCopy command fails all snapshot virtual disks associated with the target virtual disk, if any exist. 84 Using the Virtual Disk Copy Feature
