Copying The Virtual Disk - Dell PowerVault MD3200 Owner's Manual

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 166.
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, make sure 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 Logical tab and select the source virtual disk.
