BootDelete

Trigger this action to delete the secondary installation. Do not delete the secondary installation unless directed by IBM® Support.

  "BootDelete": {
  }
}

A firmware upgrade with the ApplyPatch action retains current configuration data to restore the appliance to a known, stable state if necessary. The previous firmware image and associated configuration data is referred to as the secondary installation.
