Add grid nodes to existing site or add new site
You can follow this procedure to add grid nodes to existing sites or to add a new site, but you cannot perform both types of expansion at the same time.
You have the Root access or Maintenance permission.
All existing nodes in the grid are up and running across all sites.
Any previous expansion, upgrade, decommissioning, or recovery procedures are complete.
You are prevented from starting an expansion while another expansion, upgrade, recovery, or active decommission procedure is in progress. However, if necessary, you can pause a decommission procedure to start an expansion.
