The SCSI controller for disks (or most of the other cards) has never been an IOP. The IOP (Input/Output Processor) is the processor which controls a number of slots on the bus and could be either an embedded processor like the MFIOP or a separate card in a PCI slot. The MFIOP would do some practical work like controlling the CD-ROM or a QIC tape drive, but generally, the IOPs manage overhead for the cards which do the actual work. The cards like Ethernet, disk controllers, etc. would be IOAs (Input/Output Adapters). I remember the announcement that they would be dispensing with IOPs as they move towards an Infiniband fabric bus architecture. I think that it was mentioned in Bill Z's iSeries Nation chat, although not referenced on the presentation materials. Not sure though.
