These steps must be performed to replace nodes and storage.
- Physically add the new node and storage to an existing system containing the node and storage being replaced.
- Run PUT’s Configure Teradata Vantage operation to create new AMPs/PEs on the new node with new pdisks assigned to the new storage.
- Run PUT’s Move AMPs/PEs operation to swap definitions between the old and new AMPs and PEs, copy the pdisk contents from the old AMPs to the new AMPs, and switch the AMP/PE definitions in the vconfig.txt and vconfig.gdo files.
- Run the PUT Configure Teradata Vantage operation to delete the old node (and any AMPs/PEs assigned to it) from the configuration.
- Physically remove the old node and storage.
