Removing a virtual disk from a Dell DAS array is not actually deleting any data. Rather, this action deletes the virtual disk to host/host group mapping tying the right to use the space to the host/host group. You can again assign this to the same host or to another host that can see the disk as you see fit.

1. Log into the Dell Modular Disk Storage Manager utility and click on the Mappings tab. Select the virtual disk in question and select Remove Mapping. You will be prompted with a warning screen. If you want to proceed with the removal click on Yes. Otherwise click on No to not remove the mapping.
   
   
   
2. You can verify that the mapping is no longer there by reviewing the right pane once the action is completed. Alternatively, you can go to the logical drives and confirm the actual virtual disk is still defined but is not associated to anything.
