Create Virtual Disk Copy
Description
This command creates a virtual disk copy and starts the virtual disk copy operation.
CAUTION: Before you create a new copy of a source virtual disk, stop any data access (I/O) activity or suspend
data transfer to the source virtual disk and (if applicable, the target disk) to ensure that you capture an accurate
point-in-time image of the source virtual disk. Close all applications, including Windows Internet Explorer, to make
sure all I/O activity has stopped.
NOTE: See Preparing Host Servers To Create A Virtual Disk Copy.
NOTE: Removing the drive letter of the associated virtual disk(s) in Windows or unmounting the virtual drive in
Linux helps to guarantee a stable copy of the drive for the virtual copy.
NOTE: You can have a maximum of eight virtual disk copies in progress at one time. If you try to create more than
eight virtual disk copies at one time, the RAID controller modules return a status of Pending until one of the virtual
disk copies that is in progress finishes and returns a status of Complete.
This command creates virtual disk copies in two ways:
• Virtual disk copy without snapshot (legacy)
• Virtual disk copy with snapshot (legacy)
If you use virtual disk copy without snapshot (legacy), you cannot write to the source virtual disk
until the copy operation is complete. If you want to be able to write to the source virtual disk before the copy operation is
complete, use virtual disk copy with snapshot (legacy). You can select virtual disk copy
with snapshot (legacy) through the optional parameters in the command syntax.
Syntax
create virtualDiskCopy source=”sourceName”
target=”targetName”
[copyPriority=(highest | high | medium | low | lowest)
targetReadOnlyEnabled=(TRUE | FALSE)]
copyType=(offline | online)
