Appendix B: Performing a factory reset
This section describes how to reset a deployed Dell Hybrid Cloud System for Microsoft stamp so that it can be redeployed.
Before you redeploy, you must reset backup servers, storage servers, and compute nodes to factory defaults and prepare for a fresh
deployment.
CAUTION: Performing these steps results in loss of all workload VMs running in your private cloud. Before you reset the stamp,
please make sure all important tenant VMs have been moved to another private, hosted, or public cloud. Do not move
management VMs. They are redeployed from initial state.
