Stage 2. Relocate and retire node1

12/15/2020 Contributors netapp-barbe

During Stage 2, you relocate the node1 aggregates and LIFs to node2, record node1 information, and then retire node1. This process is largely automated; the operation pauses to allow you to check its status. You must manually resume the operation.

Steps
  1. Relocate non-root aggregates and NAS data LIFs owned by node1 to node2

  2. Retire node1

  3. Prepare for netboot
