Stage 1. Prepare for upgrade

12/15/2020 Contributors netapp-barbe

During Stage 1, you must prepare the nodes for the upgrade and run a series of prechecks. You might need to rekey disks for Storage Encryption. You must also prepare to netboot the new controllers.

Steps
  1. Prepare the nodes for upgrade

  2. Get an IP address of an external key management server for storage encryption
