Dell PowerProtect DD Management Center (DDMC) 7.9 Installation and Administration Guide

Deleting Tenant Units and unassigning provisioned storage

You can delete Tenant Units, and if a Tenant Unit has provisioned storage, you can unassign that storage to be reassigned later to another Tenant Unit, or you can destroy all data. Be careful when performing this task – it cannot be undone.

1. Select Administration > Multitenancy.
2. Select a Tenant Unit in the tree, and select Delete Tenant Unit (red X) above the tree.
3. In the Delete Tenant Unit dialog, if the Tenant Unit has provisioned storage, you have two options:
   • Unassign all storage, which retains all MTrees and Storage Units that are associated with the Tenant Unit, so they can be reassigned later to another Tenant Unit.
   • Destroy all storage, which deletes all MTrees and Storage Units that are associated with the Tenant Unit.
4. Select YES to delete the Tenant Unit.
5. Observe that the Tenant Unit has been deleted from the tree.
   What to do if delete Tenant Unit fails

   When you try to delete a Tenant Unit, the operation may fail for various reasons.

   First, go to the Health > Jobs page, select the failed job, and observe the reason for the failure, which may include:

   • The file system of the system on which the Tenant Unit resides is turned off.
   • The DD system on which the Tenant Unit resides is not reachable or is powered off.
   • The DD Boost feature of the system on which the Tenant Unit resides is disabled or is not licensed.

   You can manually fix these problems using both the DD System Manager and the DDMC command line interfaces (you must fix them in both places, as they are system-related). Then, you can try to delete the Tenant Unit again using DDMC.
