Dell MD3200 Preferred RAID Controller Module Ownership, Failed RAID Controller Module, 170

Preferred RAID Controller Module Ownership

During a virtual disk copy, the same RAID controller module must own both the source virtual disk and the target virtual disk. If both virtual disks do not have the same preferred RAID controller module when the virtual disk copy starts, the ownership of the target virtual disk is automatically transferred to the preferred RAID controller module of the source virtual disk. When the virtual disk copy is completed or is stopped, ownership of the target virtual disk is restored to its preferred RAID controller module. If ownership of the source virtual disk is changed during the virtual disk copy, ownership of the target virtual disk is also changed.

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.
