Dell PowerVault MD3220 - Copy Manager; Copying the Virtual Disk

Configuration: Premium Feature—Virtual Disk Copy 159
Copy Manager
After you create a virtual disk copy by using the Create Copy Wizard, you can
monitor the virtual disk copy through the Copy Manager. From the Copy
Manager, a virtual disk copy may be re-copied, stopped, or removed. You can
also modify the attributes, such as the copy priority and the target virtual disk
Read-Only attribute. You can view the status of a virtual disk copy in the
Copy Manager. Also, if you need to determine which virtual disks are involved
in a virtual disk copy, you can use the Copy Manager or the storage array
profile.
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 might 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. See “Virtual Disk Read/Write Permissions” on page 1-1 for more
information on enabling and disabling the Read-Only attribute for the target virtual
disk.
To prevent write-protected error messages from appearing, 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 appearing.
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.
4 Select Virtual Disk  Copy  Create .
The
Create Copy Wizard - Introduction window is displayed.
