Clean up Active Directory and DNS records
If you want to redeploy a Dell Hybrid Cloud System for Microsoft stamp with the same customer prex, you must remove stale objects left
over from the previous deployment from your Active Directory and DNS databases.
1 On a domain member server or workstation with Active Directory management tools installed, open Active Directory Users and
Computers.
2 Remove the organizational unit (OU) and all child objects created by the Dell Hybrid Cloud System for Microsoft deployment. The
object location depends on the OU path and customer prex that was provided during initial deployment.
3 Open DNS Manager or another DNS management tool, and remove all A-records with a name that starts with your Dell Hybrid Cloud
System for Microsoft customer prex.
Clean up artifacts created by Azure Site Recovery
If you are using Azure Site Recovery to protect your Dell Hybrid Cloud System for Microsoft deployment, after a factory reset, the VMM
server and any Infrastructure as a Service (IaaS) VMs that were created during failover are preserved in Azure.
Unless you want to recover the VHDs for the VMs and use those VHDs to recreate the VMs, you can clean up the Azure artifacts by
deleting the current ASR settings on the VMM server and any IaaS VMs that were created during failover.
You might also want to delete the vault and the associated Azure storage account from the previous deployment. If you use a new
customer prex, during re-deployment, a new recovery services vault and a new storage account are created in Azure using the new prex
and the new deployment GUID.
IMPORTANT
: It is impossible to recover any server or service after you delete it from Azure. When you delete a storage account,
all content and resources for that account are permanently deleted. Before you perform these procedures, make sure you move
any VMs, VHDs, or other resources that you want available later to another private, hosted, or public cloud. If you plan to use the
VHDs recovered from the previous VMs to recreate new VMs, move those VHDs to a storage location outside the VMM cloud
before you perform these procedures.
If you want to clean up the Azure artifacts from the previous Dell Hybrid Cloud System for Microsoft deployment, perform the applicable
steps:
• Delete the VMM server
• Delete the IaaS VMs created during failover if needed
• Delete the old vault (optional)
• Delete the storage account for the old deployment (optional).
NOTE
: In these procedures, < Prex > indicates the customer prex that was used for the stamp.
