Recopy Virtual Disk Copy

Description

This command reinitiates a virtual disk copy operation by using an existing virtual disk copy pair.

  • NOTE: See Preparing Host Servers To Recopy A Virtual Disk.
  • 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: 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.

Syntax

recopy virtualDiskCopy target [
                                 targetName] 
                                 [source [
                                 sourceName]]
                                 [copyPriority=(highest | high | medium | low | lowest) 
                                 targetReadOnlyEnabled=(TRUE | FALSE)]
                                 copyType=(online | offline)

Parameters

Parameter Description
target Name of the target virtual disk for which to reinitiate a virtual disk copy operation. You must put brackets ([ ]) around the target virtual disk name. If the target virtual disk name has special characters, you must also put quotation marks (" ") around the target virtual disk name.
source Name of the source virtual disk for which to reinitiate a virtual disk copy operation. You must put brackets ([ ]) around the source virtual disk name. If the source virtual disk name has special characters, you must also put quotation marks (" ") around the source virtual disk name.
copyPriority Specifies the priority that the virtual disk copy has relative to host I/O activity. Valid entries are highest, high, medium, low, or lowest.
  • NOTE: CopyPriority defines the amount of system resources used to copy the data between the source and target virtual disks of a virtual disk copy pair. If you select the highest priority level, the virtual disk copy uses the most system resources to perform virtual disk copy, which decreases performance for host data transfers.
targetReadOnlyEnabled Specifies whether the target virtual disk is write enabled or read only. To be able to write to the target virtual disk, set this parameter to FALSE. To prevent writing to the target virtual disk, set this parameter to TRUE.
copyType Creates a virtual disk copy with or a snapshot which enables you to continue to write to the source virtual disk while creating the virtual disk copy. To reinitiate a virtual disk copy with a snapshot, set this parameter to online. To reinitiate a virtual disk copy without a snapshot, set this parameter to offline.
