Configuration: Premium Feature—Virtual Disk Copy 175
Failed RAID Controller Module
You must manually change RAID controller module ownership to the
alternate RAID controller module to allow the virtual disk copy to complete
under all of these conditions:
• A virtual disk copy has a status of In Progress.
• The preferred RAID controller module of the source virtual disk fails.
• The ownership transfer does not occur automatically in the failover.
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.
