HWNLM0031W Since multiple Storage Resource Groups were provided as input to the plan, the newly created volumes will not be added to any Storage Resource Groups.
Explanation
Newly created volumes will automatically be added to a Storage Resource Group only if a single Storage Resource Group is provided as input to the plan.
Action
If you want newly created volumes to automatically be placed into the Storage Resource Group, then use only one Storage Resource Group as input to the SAN Planner.
