Chapter 10. Configuration flow  261 Draft Document for Review December 5, 2019 4:33 pm 8456ch_Configflow.fm GLYPH<SM590000> The following options are available for fibre channel ports: – Configure a port to be FICON or FCP. – Distribute host connections of each type (FICON and FCP) evenly across the I/O  enclosures.  – Ensure that each host is connected to at least two different host adapters (HAs) in two  different I/O enclosures for redundancy and availability. – It is recommended to allow hosts to access all host adapter ports of the system. Note:  Avoid intermixing host I/O with Copy Services I/O on the same ports, for  performance reasons.
