Configuration: Premium Feature—Virtual Disk Copy 177
Copying the Virtual Disk
You can create a virtual disk copy by using the Create Copy Wizard.
CAUTION: Possible loss of data access – A virtual disk copy overwrites data on
the target virtual disk.
A virtual disk copy automatically makes the target virtual disk read-only to
hosts. You may want to keep this attribute enabled to preserve the data on the
target virtual disk.
CAUTION: If you decide not to preserve the data on the target virtual disk after the
virtual disk copy has completed, disable the Read-Only attribute for the target
virtual disk. For more information on enabling and disabling the Read-Only
attribute for the target virtual disk, see "Virtual Disk Read/Write Permissions" on
page 172.
To prevent write-protected error messages from being displayed, do not try to
access a source virtual disk that is participating in a virtual disk copy while the
virtual disk copy has a status of In Progress. Also, ensure that the Read-Only
attribute for the target virtual disk is disabled after the virtual disk copy has
completed to prevent error messages from being displayed.
To copy the virtual disk:
1
Stop all I/O activity to the source virtual disk and the target virtual disk.
2
Unmount any file systems on the source virtual disk and the target virtual disk.
3
In the AMW, select the

NOTE: An online virtual disk copy overwrites data on the target virtual disk and
automatically makes the target virtual disk read-only to hosts. After the online
virtual disk copy completes, use Copy Manager to disable the Read-Only
attribute for the target virtual disk. If you have used the target virtual disk in a
virtual disk copy before, make sure that you no longer need that data or have
backed it up in an accessible location.
