For both controller modules, all ports can be set to FC, all ports can be set to iSCSI, or the first two ports in each
controller module can be set to FC and the second two ports can be set to iSCSI.
set host-port-mode command will immediately change the host port configuration, stop I/O, restart both controllers, and log event 236. After the controllers have restarted, you can use the set host-parameters command to configure the individual ports.
Regarding mappings, you need to unmap all your existing volume mappings before performing Host port mode change activity. You shouldn't have same volume presented through FC and iSCSI both protocols. After host port configuration completed then you can represent volumes again with designated ports either FC or iSCSI but not combination of both for same volume.
