Stopping a Virtual Disk Copy
You can stop a virtual disk copy operation that has an In Progress status, a
Pending status, or a Failed status. Stopping a virtual disk copy that has a
Failed status clears the Needs Attention status displayed for the storage array.
Keep these guidelines in mind when you stop a virtual disk copy:
• To use this option, select only one copy pair in the Copy Manager.
• When the virtual disk copy is stopped, all of the mapped hosts have write
access to the source virtual disk. If data is written to the source virtual disk,
the data on the target virtual disk no longer matches the data on the
source virtual disk.
To stop a virtual disk copy, complete the following steps:
1
In the AMW, select
Virtual Disk
Copy Manager
.
The
Copy Manager
window is displayed.
2
Select the copy pair in the table.

Recopying a Virtual Disk
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.
