Assign a custom volume to a protection group

 

With DPM, you can assign a custom volume to store replicas and recovery points. This can maximize performance in DPM if you choose to keep certain volumes on separate LUNs (Logical Unit Numbers) to enable parallel replication onto these volumes.

After you have created and assigned a custom volume, DPM does not increase the size of this volume as it fills—the administrator must use Disk Management to perform this task. Custom volumes can be assigned only when you create a new protection group or when you add a new member to a protection group.

You cannot create a custom volume from DPM. You must create the volume by using Disk Management.
