There must be dual path to each IOM to support In-Band ACP Starting with AFF A700, AFF A300, AFF A200 and FAS9000, FAS8200, and FAS2600 series storage systems, OOB ACP is not supported. Replace IOM3 modules with IOM6 modules, and/or use IOM12 modules to provide In-Band ACP support for all storage (recommended by NetApp). Migrate to In-Band ACP, but without any ACP support for IOM3 modules.
