You can expand a workload domain by adding VxRail clusters using the SDDC Manager and VxRail Manager UIs, or using the Workflow Optimization script.
When you use the product UIs, you complete some of the steps in the
SDDC Manager UI and some of the steps in the VxRail Manager UI:
- After imaging the workload domain nodes, perform the VxRail first run (VxRail Manager UI)
- Add the VxRail cluster to the workload domain (SDDC Manager UI)
Alternatively, you can use the Workflow Optimzation script to perform all of the steps to expand a workload domain in one place. See Add a VxRail Cluster Using the Workflow Optimization Script.
