Configuration: Premium Feature—Virtual Disk Copy

To stop a virtual disk copy, complete the following steps:

1 In the AMW, select Virtual Disk Copy Copy Manager.

The 

Copy Manager window is displayed.

2 Select the copy pair in the table.
3 Select Copy Stop.
4 Click Yes.

You can recopy a virtual disk when you have stopped a virtual disk copy and 

you want to start it again or when a virtual disk copy has failed.
The Recopy option overwrites existing data on the target virtual disk and 

makes the target virtual disk read-only to hosts. This option fails all snapshot 

virtual disks associated with the target virtual disk, if any exist.

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.

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 disk copy.

Before creating a new virtual disk copy for an existing copy pair, both the host 

server and the associated virtual disk you are recopying have to be in the 

proper state. Perform the following steps to prepare your host server and 

virtual disk:

1 Stop all I/O activity to the source and target virtual disk. 
2 Using your Windows system, flush the cache to both the source and the 

target virtual disk (if mounted). At the host prompt, type 
SMrepassist -f <filename-identifier> 
and press <Enter>. For more information, see "SMrepassist Utility" on
