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)
